From Directus to KeystoneJS
Last verified:
Key pain points
Directus looks fantastic in demos, but things get rocky once you actually try to use it at scale. The Professional cloud plan is $99/month and caps you at 5 users, 75,000 database entries, and 250,000 API requests — grow past any of those limits and you're straight into custom Enterprise territory. The v12 move to the Monospace Sustainable Core License (MSCL) has also rattled the community; smaller orgs get a free Innovation Grant, but larger teams are navigating a licensing landscape that changed significantly from what they signed up for.
On the dev side, updates can introduce breaking changes, the documentation doesn't always keep pace, and the extension ecosystem is pretty thin. Localization is technically supported but fiddly and easy to misconfigure, and large datasets make the UI noticeably sluggish. And if you want anything deeply custom, you're suddenly living in Vue.js land, which is not where most teams want to spend their weekends.

Breaking update changes
Directus explicitly does not follow semver — any release may include breaking changes. The v10 to v11 upgrade hit schema changes and dropped fields, and the v11 UI scale change (px to rem) broke extensions hardcoding pixel values. Plan your upgrade windows carefully.

Limited extension ecosystem
The plugin ecosystem is still pretty bare. Anything even mildly niche ends up becoming a "let's just custom build it" moment, which defeats the purpose of picking a CMS with extensions. The marketplace launched in beta in early 2024 and is still maturing.

Complex localization setup
Yes, it supports multilingual content, but setting it up feels like assembling IKEA furniture blindfolded. It works, but expect extra config, extra steps, and extra patience.

Version history still tier-gated
Global draft versions now ship automatically with every versioned item — no manual setup required as of March 2026 — which is a genuine improvement. Full version history, rollbacks, and controlled releases are still locked behind higher-tier plans, though, so if predictable publishing workflows are a must, check your tier carefully before committing.

Vue.js knowledge requirement
Custom interfaces and deeper tweaks need Vue.js, so if your team only speaks React, prepare for a small identity crisis (or a hiring plan).

Large dataset performance issues
Heavy tables and deeply relational data can slow down queries and the UI — community reports show 25K-row datasets where raw SQL runs in milliseconds but the Directus API takes 20+ seconds, largely due to internal query overhead and no auto-indexes on foreign keys.
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.
