# KeystoneJS to Joomla migration > How to migrate from KeystoneJS to Joomla, with a side-by-side comparison and FAQs. --- ## Source: KeystoneJS - **Type:** headless - **Official site:** https://keystonejs.com - **Last reviewed:** 2026-07-28 ## 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. ## Key pain points The biggest challenge with KeystoneJS is that it hands you all the responsibility that a managed CMS would normally handle. Deployment is entirely on you, and the documentation around production hosting, Docker configuration, and scaling is thin. We've seen teams struggle to go from a smooth local development experience to a reliable production setup, especially if they don't have dedicated DevOps support. The admin UI Docker image alone can balloon to over a gigabyte, which is a headache for containerised deployments. The community around Keystone is significantly smaller than competitors like Strapi or Payload. That means fewer tutorials, fewer plugins, and slower answers when you hit an edge case. The ecosystem of ready-made integrations is almost non-existent, so you'll be building most things from scratch. For an agency working on client projects with deadlines, that time cost adds up quickly. Content editors also tend to have a harder time with Keystone compared to more polished alternatives. The admin UI is functional but feels utilitarian, and non-technical users often need more onboarding than you'd expect. There's no visual editing, no preview infrastructure, and no real content workflow features like drafts, publishing schedules, or approval chains without building them yourself. If your client's content team needs a CMS they can pick up and run with, Keystone usually isn't the answer. ### Deployment complexity Self-hosting is the only option, and the docs don't hold your hand. Getting Keystone into production requires real infrastructure knowledge, and the large Docker image sizes make it worse. ### Small community and ecosystem Compared to Strapi or even Payload, the community is much smaller. Fewer plugins, fewer tutorials, and slower support when things go wrong. ### No built-in content workflows There are no turnkey drafts, scheduled publishing, or approval chains. Keystone provides field primitives that can be assembled into publishing workflows, but you need to wire them up yourself. ### Admin UI feels dated The admin panel is functional but lacks the polish and UX of modern CMS interfaces. Non-technical editors often find it confusing and need more training. ### No visual editing or live preview There's no way for editors to see content in context before publishing. You'd need to build your own preview infrastructure, which is a significant engineering effort. ### Scaling requires significant effort Running Keystone under high traffic means managing session stores, reverse proxies, and server resources yourself. It doesn't scale as smoothly as cloud-native CMS alternatives. ## Target: Joomla - **Type:** headless - **Official site:** https://www.joomla.org - **Last reviewed:** 2026-07-28 ## Key advantages Recommending Joomla in 2026 feels a bit like recommending Internet Explorer. But if you must use it, it does earn a few real points. The multilingual support is built in, so you run a five-language site without a pile of plugins. The access-control system is more detailed than most enterprise platforms, and the modular structure gives developers room to build complex, multi-section sites. If you have a big editorial team that needs genuinely granular permissions, Joomla holds up. If you are set on Joomla and we cannot talk you out of it, we will point you to an agency that still happily ships heavy old templates. Or sit down with us for half an hour, and we will at least make sure you do not regret the journey. ### Native multilingual support Joomla ships with multilingual features baked in, so you don’t need a plugin graveyard just to run a site in five languages. It handles translations cleanly and is one of the few CMS platforms that gets this right out of the box. ### Granular user permission system Its ACL system is its biggest bragging right. You can lock down roles, workflows, and access rules with a level of control that most CMS platforms still envy. ### Custom field capabilities Joomla gives you solid flexibility with custom fields, letting you shape structured content without hacking together a dozen extensions. It’s powerful enough for complex layouts and multi-section content. ### Active developer community The community isn’t massive, but the people who are there are dedicated, technical, and still shipping useful extensions and documentation. If you're deep in Joomla land, it’s a lifeline. ### Strong security foundation Kept patched, Joomla is stable and the core team takes security seriously, with regular updates. The catch is the "kept patched" part. The 2026 JCE editor exploit hit sites that fell behind, so the upkeep is on you. ### Modular architecture flexibility Its module-based layout system lets you build multi-section portals, dashboards, and content-heavy sites without bending the platform backward. If you know what you're doing, it’s flexible enough to scale. ## 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. ## Frequently asked questions ### 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. ### 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. ### 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.
