## Verdict

Joomla has two real strengths worth acknowledging before any comparison: a native permissions
system that ranks among the best in open source (unlimited hierarchical groups, with
inheritance and a four-level permission cascade) and multilingual support in core since 2011,
no plugins required. Its engineering isn't idle either: five releases in 2026, two branches
maintained in parallel, and cryptographically signed updates.

The problem for a university evaluating in 2026 sits on a different layer. Joomla has no
multisite in core and has gone fifteen years without resolving it: the official design
document states there is "no formal consensus" since 2011, the formal request was closed
unimplemented in 2018, and in March 2026 a core maintainer replied that "the work has stalled
again due to its complexity." The best practice the official documentation itself recommends
is one installation and one database per site: the opposite model to a governed ecosystem.

There's no SSO, SAML, or Shibboleth in core, and all the federated authentication a university
needs depends on a single external commercial vendor.

And the figure that sums it all up: 52.3% of the world's Joomla installations run Joomla 3,
unsupported since August 2023 and with no patching path available, not even paid, since
February 2025. That stops being a risk hypothesis the moment you look at the W3Techs census.


*Genuinely good native permissions and multilingual support. No multisite, no SSO, and more than half its installed base unpatched since 2023.*

## Feature-by-feature comparison

| | Griddo | Joomla | Advantage |
|---|---|---|---|
| Managing multiple websites (multisite) and large ecosystems | Native from the core, with global and local data, design inheritance, and centralized brand governance: one client manages 60 sites in 8 languages from a single instance. IE University runs 43 sites and more than 60,000 pages today, and Universidad Europea operates five instances with a single team of 16 people. No documented scale ceiling. | No multisite in core, and the gap has gone unresolved for fifteen years: the official design document states there is 'no formal consensus on which approach to take,' capturing discussions from 2011 and 2012, the formal request (issue #22254, 2018) was closed unimplemented, and in March 2026 a core maintainer replied to the new RFC that 'the work has stalled again due to its complexity.' It sits on the Joomla 7 roadmap with status 'Looking for Volunteers.' The best practice the official documentation recommends is giving each site its own domain, installation, and database. The third-party market trying to fill the gap is five extensions in the entire official directory, only two of which are real, maintained multisite tools: the one with the largest user base hasn't been updated since December 2023 and doesn't declare Joomla 6 compatibility, and the only live one states outright that it cannot run 'hundreds or thousands of sites' and shares content all-or-nothing by table type, with no granularity by faculty or section. | Griddo |
| Granular permissions and editorial governance | RBAC with six built-in roles (Super Admin, Administrator, Viewer, Webmaster, Editor, SEO Validator), permissions by content type, at page level, and with API token scope. Full audit trail of every edit, publication, and SEO change, attributed to user, site, and date. Comillas runs one instance with 60 people from 31 departments, faculties, institutes, and chairs at once. | Genuinely one of its greatest strengths, and the feature its users praise most intensely: unlimited hierarchical user groups with inheritance, viewing access levels, and a four-level permission cascade (global configuration, component, category, item). A webmaster on G2 (March 2026) describes it as 'still unmatched for managing content access.' The limits: it governs visibility and permissions, not personalization or segmentation; the native editorial workflow only covers articles, with no conditional routing; and there's a documented architectural tension between permission granularity and scale, because the permission tree is stored as a nested set and every write gets more expensive. | — |
| Multilingual | Native in core: translations, hreflang, and local SEO from day one, no plugins. Automatic AI translation built into the editor. | Also native in core since 2011, no extensions: its second real strength, and a clear advantage over WordPress, which needs WPML or Polylang. 66 accredited language packs. Three verified nuances: the model is document-level (one article per language linked by association, no field-level translation), there was no language fallback chain until Joomla 6.2, and coverage has regressed (Joomla 3 had 84 accredited packs, Joomla 6 has 66), so migrating can mean losing the existing language pack. The project's translation team is a single person. | — |
| Real ease of use (per its own users) | Live Author Experience, WYSIWYP ('what you see is what you publish'), no code, with an error panel and SEO validation before publishing. Measured, auditable autonomy: 90.8% of productive activity and 96.9% of publications are carried out by the institutions themselves, across 42,414 actions from 137 distinct people in a single month. | Ease of Use on Capterra: 3.7 out of 5, its lowest subscore, below its overall rating (4.2) and Value for Money (4.3). On G2, 7.5 out of 10. The dominant complaint in the reviewed corpus, by a wide margin, is the learning curve (~18 distinct reviewers), followed by the dated back office (~9). TrustRadius's synthesis of recent reviews is explicit: 'beginners face a steep learning curve and drag-and-drop functionality remains poor.' The profile Joomla works for, a technical user with years of learning investment, is the opposite of a faculty's decentralized editor. | Griddo |
| Native functionality vs. dependence on extensions | Visual page editor, form builder with steps and conditional fields, embedded Design System, document manager with permanent URLs, image manager with automatic tagging, XML sitemaps, 301/302 redirect manager, semantic search and AI: all built in, on one platform and one invoice. | The core handles classic content management well, but doesn't ship a visual page builder, form builder, XML sitemap, real DAM, A/B testing, personalization, analytics, editorial calendar, or webhooks. For a university site, that means buying and maintaining 8 to 12 third-party extensions (editor, forms, page builder, SEO, sitemap, SSO, backup, multisite), each with its own lifecycle and its own patching schedule. The directory has 4,913 extensions, versus 56,421 Drupal modules and more than 72,000 WordPress plugins. | Griddo |
| Single sign-on (SSO) and academic federations | Native SAML 2.0, LDAP, Active Directory, and OAuth, with multi-factor authentication. | No SAML, Shibboleth, OAuth/OIDC, or Azure AD in core. All federated authentication depends on extensions from a single external commercial vendor (miniOrange, $149 to $449/year, with support for multiple identity providers, necessary for federations like SIR/RedIRIS, InCommon, or eduGAIN, reserved for the top-tier plan). For Shibboleth, Joomla's own documentation points to that vendor's guide. And the one piece of corporate identity the project maintains itself, the LDAP plugin, has accumulated open, unresolved issues since 2017, the latest reported against Joomla 5. | Griddo |
| Integrations (CRM and academic systems) | Native connectors with HubSpot, Salesforce, Dynamics 365 and Zoho, with real-time sync, plus Apollo for contact enrichment. Academic systems (SIS/LMS/ERP) via configurable webhooks and REST API. | No enterprise connector ecosystem: no documented integration with SAP or Microsoft Dynamics, the only Salesforce extension in the directory is one-way lead capture, and the reference Salesforce extension is unpublished from the directory over a broken link. For Moodle there is a genuinely good, maintained integration (Joomdle, GPL, free, updated in July 2026 and compatible with Joomla 6), better than quite a few commercial DXPs, and that's worth acknowledging. For Banner, Slate, PeopleSoft, or SITS we found no documented integration. | Griddo |
| Platform architecture and headless capability | Headless / MACH: microservices, API-first (REST, with a separate public and private API), cloud-native and serverless on AWS. Content stored as structured, described data, consumable by both humans and AI systems. | A server-side PHP monolith with plain PHP templates (no Twig-style templating engine), two-pass rendering via tag substitution, manual escaping, and jQuery 3.7 still a core dependency in 2026. The JSON:API exists and is functional, but the project itself acknowledges: 'Joomla was not originally designed as an API-first CMS... complex use cases may require custom development.' No official OpenAPI specification, no GraphQL, no native webhooks, and no official SDK in any language. Content is stored as plain HTML, not structured data. | Griddo |
| Artificial intelligence and GEO | AI Booster (DeepL translation, SEO/GEO metadata with OpenAI, image tagging with Amazon Rekognition) and conversational AI Search with cited answers, in production and on a single invoice. Automatic JSON-LD structured data for AEO and five GEO mechanisms (configurable robots.txt, llms.txt, a markdown mirror of every page, Link Headers, Markdown content negotiation, and OKF packages) generated from the content the university is already publishing. | Nothing in core. The AI Framework is a standalone Composer package born as a Google Summer of Code 2025 project, with 'In Planning' status on the roadmap. The MCP server, the project's most interesting piece, is an 'In Progress' proof of concept not in Joomla 6.1 and not announced for 6.2. A community AI proposal for Joomla 6 was tagged 'Feature:Backlog' with three participants. All real functionality lives in third-party extensions. | Griddo |
| Lifecycle, patching, and security exposure | Continuous updates and technical maintenance included in the subscription on every plan, with no additional migration project and no version end-of-life to manage. MACH architecture with static generation and CDN reduces the attack surface; WAF, encryption in transit and at rest, and a full audit trail of every action. | The security team is mature and transparent (numbered public advisories, a stated 24-hour SLA for acknowledgment and 21 days for resolution) and its record isn't overrepresented in compromised-site studies. The problem is the lifecycle and the extensions. The LTS scheme was dropped in 2014: today it's roughly 4 years per major version, forcing at least one migration within a 5-to-8-year university contract. And the outcome is measured: 52.3% of the world's Joomla installations run Joomla 3, unsupported since August 2023 and with no patching path available, not even paid, since the extended support program closed in February 2025; 62.6% of the installed base is on unsupported versions and only 8.6% on the fully supported one. On top of that, the real attack vector is third-party extensions: in 2026 there were three actively exploited CVSS 10.0 vulnerabilities, including the ecosystem's most widely installed WYSIWYG editor, with a CISA emergency patching directive. The project's own vulnerable extensions list warns bluntly: 'We do NOT promise to test or validate these reports.' | Griddo |
| Price and transparency | Four plans with public pricing from €1,500/month (Institute, 1 site) to €5,000/month (University, 9 sites). Additional sites in tiers from €150/month. Public implementation fee of €7,500, waived when contracting Griddo Cloud. Discounts for quarterly (3%), annual (6%), and biennial (10%) billing. | The core is free, under GPLv2-or-later, verified in the source code, and the official directory requires unencrypted GPL licensing for every extension, so none can revoke the right of use. It's Joomla's strongest point and it's not up for debate. What doesn't exist is a comparable platform figure: the cost is spread across hosting, 8 to 12 annual extension subscriptions, agency implementation with no standardized market rate, and a major migration roughly every 4 years. No total cost of ownership study for Joomla exists with a published methodology, either general or specific to higher education. | Griddo |
| Contractual accountability and public-procurement documentation | 99.99% uptime SLA guaranteed by contract on the Enterprise model, with defined response times and an assigned Customer Success Manager. 8/5 technical support with SLA and 24/7 monitoring on every plan. Data processing agreement (DPA) available. AWS Qualified Software Partner, having passed the Foundational Technical Review. | There's no counterparty to sign with. The project has no ISO 27001 or SOC 2 (and structurally can't, because Joomla is distributed software and the entity behind it runs no service), publishes no accessibility conformance statement (VPAT/ACR), and its current accessibility statement dates to December 2022 and describes Joomla 4, offers no SLA, and there's no identifiable data controller to sign a GDPR Article 28 DPA with. An integrator can supply these, but then what's certified is the integrator's own operation, whose scope doesn't cover the CMS lifecycle or the third-party extensions the site depends on. | Griddo |
| Deployment model (on-premises / cloud) | Cloud-native (MACH) by design, on AWS serverless and edge computing across more than 300 nodes. Two models: managed Griddo Cloud, or Enterprise, where the university contracts directly with AWS and chooses the region (Europe by default for European universities), retaining ownership of the infrastructure contract. No on-premises route. | Genuinely on-premises, with no restrictions: it's the default, best-supported model, self-hostable on any server or cloud meeting the requirements, with a perpetual license and no need for connectivity to any project infrastructure. That's more infrastructure freedom than Griddo offers. What doesn't exist is any official Joomla cloud: the free evaluation service is run by a third party with 500 MB and manual renewal every 30 days, and the free SaaS the project itself announced with a hosting partner isn't accepting new accounts and has an expired TLS certificate as of this comparison's date. There's also no official high-availability guide or maintained Helm chart. | — |
| Analyst recognition | No documented presence in independent analyst quadrants as of this comparison's date. | Absent from all of them: not in the 2024 Gartner Magic Quadrant for DXP (14 vendors) or 2025 (17), not in the 2025 IDC MarketScape for headless CMS (9), not in Gartner Peer Insights (neither Web Content Management, which returns a 404, nor DXP, where vendors with nine reviews do appear), not in G2's DXP category, and not in CMSWire's 2026 DXP guide. The absence isn't explained by size: inclusion criteria require an identifiable commercial vendor with license revenue, something a project with no commercial entity cannot meet. | — |

## Pricing comparison

| | Griddo | Joomla |
|---|---|---|
| Entry price (tier with a fully functional site) | €1,500/month (Institute, 1 site, up to 3) | €0 license (open source core, GPLv2-or-later, perpetual), but no functional site out of the box: it requires implementation, hosting, and 8 to 12 third-party extensions to cover forms, a visual editor, SEO, sitemap, SSO, and backup. There's no equivalent entry tier that bundles platform, hosting, support, and maintenance in a single fee. |
| Initial implementation cost | €7,500, a single public fee, waived when contracting Griddo Cloud | No public figure. It depends entirely on the contracted agency's rate, and we found no verified market rate for Joomla agencies in Spain or Latin America. The only references we located are ranges published by interested agencies ($15-40/hour in Asia, $40-70 in Eastern Europe, $60-150 in Western Europe and the US), not an independent market survey. |
| Extension cart for an institutional site | €0 extra: visual editor, forms with steps and conditional logic, SEO, sitemaps, redirects, DAM, document manager, semantic search, and AI are included in the plan. | Between roughly $432 + €174 (single institutional site) and $1,535 + €319 (multisite portal with academic federation) in the first year, adding up a page builder, forms, SEO, analytics, security and backup, multi-IdP SSO/SAML, multisite, and commerce. In absolute terms these are low figures that don't move any university's budget: the real cost is maintaining 6 to 8 independent vendor relationships, with 6 to 8 renewal cycles, their own roadmaps, compatibility failure points on every major update, and distinct attack surfaces. |
| Software support and maintenance | Included in the subscription on every plan: continuous updates, full technical maintenance of the AWS infrastructure, 8/5 support with SLA, and 24/7 monitoring with incident response. | No commercial support from the project on any version. The only paid program that ever existed, extended support for Joomla 3 at €90/site, closed on February 17, 2025, and its own page states that 'no new updates will be released.' Since then there is no path, free or paid, to receive patches for the 52.3% of the installed base. Outsourced agency maintenance runs €348-1,548/year per site, per the published rates we located. |
| Hosting and infrastructure | Included: two models, Griddo Cloud managed by Griddo, or Enterprise with an AWS contract directly in the university's name and choice of region. | Not included, with no offering from the project itself. It's contracted on the open market: shared hosting from roughly $360-540/year per site at real renewal price (not promotional), or managed cloud from roughly $11/month per server. For a 30-to-60-site ecosystem, our composition of the project's official host's published rates puts infrastructure at $8,000-20,000/year, our own estimate, not a sourced figure. |
| Estimated 3-year total cost (mid-size university) | Calculable from public prices: from roughly €61,500 (Institute, 1 site, with implementation) to roughly €187,500 (University, 9 sites). No hidden variables. | No total cost of ownership study for Joomla exists with a published methodology, either general or specific to higher education, and the most complete 2026 higher-ed CMS guide we located, which does put a 3-year TCO on Drupal ($180,000-520,000) and WordPress multisite ($95,000-280,000), doesn't mention Joomla at all. |

## Who each platform is for

**Griddo is ideal if…**

- Universities with multiple faculties, campuses, or brands that need a governed ecosystem from a single platform, without multiplying installations, updates, and attack surfaces by N
- Institutions that already have dozens of Joomla installations scattered across faculties and departments and want to consolidate them under brand governance, instead of migrating the main site and leaving the rest unpatched
- Teams that need federated SSO, CRM connectors, semantic search, AI, and GEO out of the box, without evaluating, buying, and maintaining a third-party extension for every capability
- Institutions that must supply an SLA, an Article 28 DPA, and an identifiable contractual party in an RFP, something a project with no commercial entity cannot sign
- Non-technical communications teams that need real autonomy from day one, backed by usage evidence

**Joomla is a fit if…**

- Institutions with a single institutional site, an internal technical team with real Joomla experience, and the priority of keeping license cost at zero
- Projects where the dominant requirement is a very granular permissions model over restricted-access content (member portals, intranets, tiered content), which is where Joomla's native ACL performs best
- Universities that need true on-premises deployment, in their own data center or an isolated environment, with the guarantee that the software will remain free and perpetually usable no matter what happens to any vendor
- Institutions for which digital sovereignty is a public-policy requirement, and who value Joomla's recognition as a Digital Public Good by the UN-backed alliance

## Frequently asked questions

### Can Joomla manage a university's ecosystem of sites?

Not with a single installation, and this is the single most important point in the whole comparison. Joomla has no multisite in core: the official design document states there is 'no formal consensus on which approach to take,' capturing discussions from 2011 and 2012; the formal request was closed unimplemented in 2018; and in March 2026 a core maintainer replied to the new RFC that 'the work has stalled again due to its complexity.' It sits on the Joomla 7 roadmap with status 'Looking for Volunteers.' The best practice the official documentation itself recommends is giving each site its own domain, installation, and database: for a university with forty sites, that's forty core updates, forty extension inventories, forty permission configurations, and forty attack surfaces, with no design inheritance and no central governance. The extensions trying to solve it are five in the entire official directory, and the only maintained one states outright that it cannot manage 'hundreds or thousands of sites.'

### How much does Joomla actually cost?

The core is genuinely free, no caveats: GPLv2-or-later, perpetual use, no limit on installations or traffic, and the official directory requires unencrypted GPL licensing for every extension, so none can revoke the right of use. That point isn't up for debate and it's Joomla's greatest strength. The real cost sits elsewhere: hosting (no offering from the project itself), 8 to 12 annual extension subscriptions to cover what the core doesn't ship (forms, visual editor, SEO, sitemap, SSO, backup, multisite), agency implementation with no standardized market rate, and a major migration every four years. Individual extension costs are low in absolute terms (between roughly $432 + €174 and $1,535 + €319 in the first year); what actually costs money is maintaining six or eight vendor relationships with independent roadmaps. And no total cost of ownership study for Joomla exists with a published methodology to compare against.

### Is Joomla secure for an institutional website, and what happens if we stay on an old version?

Joomla's security team is mature and transparent (numbered public advisories, a stated 24-hour SLA for acknowledgment and 21 days for resolution) and, contrary to what's often assumed, compromised-site data doesn't show it overrepresented relative to its market share. The real risk sits on two other layers. The first is the lifecycle, and it isn't hypothetical: 52.3% of the world's Joomla installations run Joomla 3, which lost project support in August 2023 and lost even paid extended support in February 2025. Since then there is no path, free or paid, to receive a patch. 62.6% of the installed base is on unsupported versions, and only 8.6% on the fully supported one. The project itself documents the cause: moving from Joomla 3 to 4 was a migration, not an update, and it depended on every extension being ported (the official catalog went from over 8,000 extensions to 4,913). Joomla improved the mechanism afterward, with automatic core updates in version 6 and a backward-compatibility plugin, but the improvement arrived after most of its user base had already fallen behind; and Joomla 5, with 20.6% of the installed base, loses bugfix support on October 13, 2026. The second layer is third-party extensions, which is where the real attack vector lives: in 2026 there were three actively exploited CVSS 10.0 vulnerabilities in Joomla extensions, including the ecosystem's most widely installed WYSIWYG editor, which CISA added to its Known Exploited Vulnerabilities catalog with an emergency patching directive for federal agencies, plus two rated 9.8 with confirmed exploitation by Singapore's cybersecurity agency, one of them in the most widely used commercial page builder. And core alone racked up 50 security advisories in 2026 through September versus 9 in all of 2025, roughly thirteen of them about API endpoint access control. The project's own vulnerable extensions list warns bluntly: 'We do NOT promise to test or validate these reports.'

### Can Joomla be installed on-premise?

Yes, with no caveats, and it's its default, best-supported model: free software you can self-host on any server or cloud meeting the technical requirements, with no need for connectivity to any project infrastructure, under a perpetual license. On that front it offers more infrastructure freedom than Griddo, which is cloud-native on AWS. What doesn't exist is any Joomla cloud: the free evaluation service is run by a third party with 500 MB and manual renewal every 30 days, and the free SaaS the project itself announced with a hosting partner isn't accepting new accounts and has an expired TLS certificate as of this comparison's date. There's also no official high-availability guide, no maintained Helm chart, and no declaratively exportable configuration: the question 'is it possible to update Joomla via a CI/CD pipeline?' has been open on its GitHub since September 2021. Griddo's Enterprise model isn't on-premises either, but it lets the university contract directly with AWS and choose the region, retaining ownership of the infrastructure contract.

### What feature do Joomla users value most?

Based on the thematic tally of real reviews across G2, Capterra, and TrustRadius, the most intense praise, the kind that reaches for superlatives, concentrates on two core capabilities: the permissions system and multilingual support. A webmaster on G2 sums it up: Joomla's ACL is 'still unmatched for managing content access... lets you build unlimited levels.' Both are free, both are in core, and both are defined by contrast with WordPress, which needs plugins for either. What's revealing is the contrast with the project's own messaging, which in its 2025 strategy declares itself 'AI-Ready': not a single review in the analyzed corpus mentions AI, personalization, or orchestration as a reason for value. It's the same pattern we've found in TYPO3, Drupal, and Ibexa: buyers reward strong execution on the basics, not novelty in the pitch.

### Does Joomla meet the accessibility requirements of a public university?

Today it can't prove it with a document, though it's investing seriously to get there. The serious part: in July 2026 a twenty-month program funded by the German Sovereign Tech Fund kicked off, with nine phases, twenty milestones, and independent auditing, aimed at WCAG 2.2, the European Accessibility Act, and Germany's BFSG. It's the most ambitious accessibility commitment of any volunteer-governed open source CMS, and it deserves credit. The current state: no VPAT or accessibility conformance report has been published, the current statement dates to December 2022 and describes Joomla 4, WCAG 2.2 AA conformance remains 'In Planning,' and the text itself admits that 'our own websites do not currently meet accessibility guidelines' and explicitly disclaims responsibility for the accessibility of third-party templates and extensions, which is where most of the HTML an end user sees actually lives. For an RFP requiring EN 301 549 under Spain's Royal Decree 1112/2018, or a VPAT-based ACR under US Section 508, the bidder can't supply the document being asked for, and the project's first independent audit results won't arrive before 2028 on its own timeline.

### If we migrate from Joomla to Griddo, what systems does it integrate with?

Griddo has native connectors with HubSpot, Salesforce, Dynamics 365, and Zoho, with real-time sync and contact enrichment via Apollo, plus GA4, GTM, Hotjar, Clarity, AB Tasty, Matomo, Mailchimp, and Cloudinary, out of the box with no module to maintain. And it ships native SAML 2.0, LDAP, Active Directory, and OAuth with multi-factor authentication, the entry requirement for any university. Joomla has no enterprise connector ecosystem: no documented integration with SAP or Dynamics, and the reference Salesforce extension is unpublished from the official directory. It also has no SAML, Shibboleth, or OAuth/OIDC in core (it does have passkeys and WebAuthn, genuinely good), so all federated authentication depends on extensions from a single external commercial vendor, with support for multiple identity providers reserved for its top-tier plan; for Shibboleth, Joomla's own documentation points to that vendor's guide. There's one exception worth acknowledging: for Moodle there's a genuinely good, free, maintained integration (Joomdle, updated in July 2026 and compatible with Joomla 6), better than quite a few commercial DXPs. For the rest of the academic stack (Banner, Slate, PeopleSoft, SITS, Workday Student) neither platform ships a packaged connector: Griddo solves it with configurable webhooks and a REST API, and on Joomla it's custom development against an API the project itself acknowledges is incomplete and has no official OpenAPI specification.
