Challenges with Joomla
Key pain points
Joomla sits in the same bracket as WordPress, except it is somehow even harder to explain to anyone under 40. If your C-suite still thinks “PHP developer” is a personality type, Joomla will make them feel right at home. You will also keep your hosting provider happy, because nothing about this platform is light or low-maintenance.
The dev experience feels stuck in a pre-Composer, pre-type-hints era. Major upgrades are the real horror story. Joomla 3 and 4 both went end of life in October 2025, and moving up a major version tends to break extensions and templates badly enough that you rebuild the site anyway. The community is smaller than WordPress's, the documentation is hit-and-miss, and the admin panel feels like a government portal that accidentally became a CMS. Performance on shared hosting is shaky and the editing workflow is clunky. If you really, truly still want Joomla, we will point you to another agency, or sit down with us for half an hour and we will talk you out of your biggest digital regret.
Steep learning curve
Joomla makes even simple tasks feel like you’re onboarding into a new corporate ERP system. If you’re not already fluent in its quirks, prepare to lose a weekend (or three).
Outdated coding standards
Still clinging to older PHP conventions, missing modern practices, and generally stuck in a time capsule. If you enjoy fighting your own tools, you’ll love it.
Complex migration process
Upgrading versions feels less like an update and more like a full-blown rebuild. Random extensions break, templates combust, and you’re left questioning your career choices.
Extension compatibility issues
Half the ecosystem works… depending on your version, your template, the time of day, and whether Mercury is in retrograde. Reliability is not its strong suit.
Limited template selection
Unless you’re aiming for “government website from 2011,” the design ecosystem doesn’t give you much to work with.
Interface complexity barriers
The admin panel still feels like an escape room puzzle. Everything is technically there, but actually finding or using it is another story.
Benefits of KeystoneJS
Key advantages
KeystoneJS is one of those tools that really clicks if your team thinks in code. It's a schema-driven, open-source headless CMS built on Node.js, and the developer experience is genuinely good. You define your content models in TypeScript, Keystone generates a GraphQL API and an admin UI for you, and you're off. There's very little magic or abstraction hiding what's happening under the hood, which we appreciate when building complex projects for clients.
The Prisma ORM integration is a real highlight. Automatic migration generation, type-safe database access, and support for PostgreSQL, MySQL, and SQLite mean you're not fighting your data layer. If you've ever had to wrangle a CMS into supporting a non-trivial relational content model, you'll understand why this matters. Keystone lets you express those relationships cleanly and query them with a proper GraphQL API.
The document field editor is also worth mentioning. It's one of the more thoughtful rich text implementations we've seen in a headless CMS. You can embed custom React components directly into the editor, which means content teams can work with your actual design system components rather than generic blocks. For teams that care about structured content, Keystone gives you real tools to enforce it.
Where Keystone really shines is in projects where the development team wants full ownership of the stack. There's no vendor lock-in, no proprietary query language, and no surprise pricing tiers. If you want a CMS that feels like a well-designed library rather than a platform, Keystone delivers on that promise.
Schema-as-code with full TypeScript support
Define your entire content model in TypeScript with strong type inference throughout. The schema drives everything from the database to the admin UI to the GraphQL API.
Automatic GraphQL API generation
Every content type you define automatically gets a full CRUD GraphQL API with filtering, pagination, and relationship resolution. No manual endpoint wiring needed.
Prisma-powered database layer
Built on Prisma ORM with automatic migration generation and type-safe queries. Supports PostgreSQL, MySQL, and SQLite out of the box.
Flexible document field editor
The rich text editor supports custom embedded components that map to your design system, giving content editors structured authoring without sacrificing flexibility.
Granular access control
Fine-grained, field-level access control defined in code. You can write custom logic for create, read, update, and delete operations per field or per list.
Fully open source with no vendor lock-in
MIT licensed with no paid tiers or proprietary features gated behind a subscription. You own the entire stack and can host it wherever you want.
Common questions
Joomla to KeystoneJS migration FAQs
Answers to the most common questions about Joomla to KeystoneJS migration
Is Joomla free?
Yes. Joomla is open-source software under the GPL, so there is no licence fee and you can download Joomla 6 and self-host it for nothing. The real cost is everything around it. You pay for hosting, for any commercial extensions and templates you bring in, and for the developer time that keeps it patched and upgraded. Treat the price tag as hosting plus extensions plus maintenance, not a SaaS subscription. On a busy site those running costs add up fast, which is the part most "Joomla is free" claims quietly skip.
Can I migrate from Joomla to Sanity?
Yes, and it tends to be cleaner than a Joomla version upgrade. Joomla stores everything in MySQL, so we script the content extraction, map your articles, categories, and custom fields into a Sanity content model, and rebuild the frontend in Next.js. For a typical site of 500 to 2,000 pages, budget 6 to 12 weeks. The extraction takes a few days. The rest goes on the new frontend, replacing whatever your extensions used to do, and mapping 301 redirects so you keep your search rankings. The payoff is no more PHP version juggling and no near-rebuild every time the platform bumps a major version.
What are Joomla's main limitations?
Three things bite. First, major upgrades are brutal. Joomla 3 and 4 both reached end of life in October 2025, so anyone still on them is running unpatched software, and moving up a major version often breaks extensions and templates badly enough to feel like a rebuild. Second, the extension and template ecosystem is small next to WordPress, and maintainers keep drifting away. Third, the developer experience is dated and the admin panel is hard to navigate, so editor productivity suffers. Security upkeep is on you too, as the JCE editor exploit doing the rounds in 2026 reminded plenty of sites.
Joomla vs WordPress vs headless, which should I pick?
For a content site you want to keep cheap and simple, WordPress wins on ecosystem size and the sheer number of developers who know it. Joomla's honest edges are native multilingual and its access-control system, so it makes sense if you genuinely need granular permissions across a big editorial team. But both are PHP monoliths that tie your content to your frontend. If you care about performance, want a modern build with React or Next.js, and plan to push content to a web app, a mobile app, and a few other places at once, go headless. We pair Sanity with Next.js for exactly that, and it is where most teams leaving Joomla end up.
What makes migrating from KeystoneJS difficult?
KeystoneJS stores data through Prisma, so the database layer is well-structured and easy to export. The harder part is replacing everything Keystone doesn't give you. Most Keystone projects have custom-built preview systems, publishing workflows, and access control logic that are tightly coupled to the Node.js backend. Rebuilding those features in a new CMS takes planning. We typically budget 4 to 8 weeks for a Keystone migration depending on how much custom infrastructure the team has built around it.
Why do teams move away from KeystoneJS?
Deployment complexity is the number one reason. Teams love Keystone during local development, then hit a wall getting it reliably into production. The Docker images can balloon past a gigabyte, the docs don't cover production hosting well, and there's no managed hosting option. The small community compounds this problem. When you hit an edge case, there are fewer people who've solved it before. Content editors also struggle with the admin UI, which lacks visual editing, live preview, and built-in publishing workflows that competing platforms ship by default.
How do we extract our content from KeystoneJS?
Since Keystone uses Prisma ORM, your content lives in standard PostgreSQL, MySQL, or SQLite tables with clean schemas. You can export directly from the database using SQL dumps or Prisma's query API. The content model is defined in your TypeScript codebase, so mapping fields to a new CMS is straightforward. We write automated scripts that handle the data transformation, including resolving relationships between lists and migrating file references. For a project with 20 to 50 Keystone lists, extraction and transformation usually takes 1 to 2 weeks.
