# Prismic to KeystoneJS migration > How to migrate from Prismic to KeystoneJS, with a side-by-side comparison and FAQs. --- ## Source: Prismic - **Type:** headless - **Official site:** https://prismic.io - **Pricing:** https://prismic.io/pricing - **Last reviewed:** 2026-07-28 ## Key advantages Prismic is phenomenal for simplistic page-builder-style websites. Its simplistic drag-and-drop page builder, along with the newer code-based version, helps you generate like-for-like components and automates the developers' process. The built-in media optimisation tool is also great, so you can ensure that even if you're uploading 4mb images, they're going to be scaled down with minimal compression artefacts. ### Content scheduling capabilities Prismic makes it ridiculously easy to plan content ahead with built-in scheduling without any plugins or workarounds. Just pick a time, hit schedule, and your release goes live exactly when you want it. ### Intuitive visual editor The editor feels natural even for non-technical teams, with clean previews and simple fields. It keeps the writing flow distraction-free while still giving developers structure. ### Efficient slices feature Slices let you build repeatable, flexible components that marketers can rearrange without breaking layouts. It’s the closest thing to structured Lego-blocks for content teams. ### Rich media embedding Embedding images, videos, and rich assets takes seconds. You don't need to hack templates. Just paste, pick, and publish. ### Flexible component reuse Developers create once, marketing teams reuse forever. Slices and custom types make content scalable without adding complexity. ### Drama-free publishing Publishing is fast, predictable, and drama-free. If you want to do a small tweak or a full-page release, everything ships smoothly with minimal cognitive load. ## Key pain points We have a long history with Prismic, and at one point, we were agency partners, so count us as biased. However, if you're anything like us, we've had an absolutely terrible experience with Prismic. They've historically changed their API ad hoc, resulting in many broken websites, which is especially bad for an agency. They've dumped infrastructure on the community, resulting in expensive migration bills and client dissatisfaction and they've updated their system with no way to migrate other than to rebuild your entire website for literally years. If you're having a hell of a time, we can help you move away and do it without breakages. We've had to migrate quite a few folks and we have a standardised process that lets us migrate images, videos, text and content structure to the platform of your choice. ### Dependency on third-party hosting You don’t control the infrastructure, Prismic does. So you’re tied to their uptime, limits, and CDN behaviour. ### Limited native integrations Most serious integrations require extra tooling or custom code because Prismic’s built-in ecosystem is pretty thin. ### Steep learning curve Slices, custom types, and the editor workflow take time to understand, especially for teams new to component-driven CMS structures. ### Lack of built-in versioning There’s no full document history or global rollback, meaning mistakes are harder to recover from without workarounds. ### Escalating pricing model Costs jump fast as you add seats, locales, or repositories, making it expensive to scale a growing content team. ### Limited out-of-box features Beyond basic content creation, most advanced needs require custom development, external tools, or plugins. ## Target: 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. ## Frequently asked questions ### How much does Prismic cost? Prismic has a free plan for 1 user with limited API calls. The Starter plan is $10/month per repository for small teams. The Small plan is $25/month per repository for up to 7 users with more locales and API bandwidth. Medium is $150/month per repository. Large and Enterprise plans go higher. The pricing jumps are significant once you need multiple locales or repositories. We've had clients hit the ceiling on the Small plan faster than expected because of how Prismic counts API calls and custom types. ### What are the best Prismic alternatives? Sanity is the alternative we recommend most. It gives you better content modelling, real-time collaboration, and a query language (GROQ) that's far more flexible than Prismic's API. Contentful is another option with a bigger ecosystem, though pricing is steeper. If you liked Prismic's Slices concept, Sanity's block-based content approach works similarly but with more depth. We've migrated multiple former Prismic agency partners to Sanity, and the developer experience improvement is always the first thing they mention. ### Can I migrate from Prismic to another CMS? Yes. We've migrated quite a few Prismic projects, mostly to Sanity. We export your custom types, documents, and media through Prismic's API, then restructure everything for the target platform. Prismic's Slice-based content maps well to Sanity's portable text and block system. Typical migrations take 3-5 weeks. We keep your existing Prismic site live throughout, so there's no downtime. The biggest challenge is usually handling Prismic's media library, since images need to be moved to a new CDN. ### Is Prismic a good CMS for developers? It's decent for simple projects. The Slice Machine tooling is clever and the TypeScript support has improved. But Prismic's API has limitations that frustrate developers on bigger projects. You can't do complex queries, filtering is basic, and the content modelling is shallow compared to Sanity or Contentful. The bigger issue is Prismic's track record of breaking API changes and infrastructure shifts that have caused production outages. Developers who need reliability and deep customization are better served elsewhere. ### Why are teams leaving Prismic? The main reasons we hear are API instability, limited content modelling depth, and pricing that doesn't match the feature set. Prismic has a history of making breaking changes to their API and infrastructure without adequate migration paths. One major version change left agencies (including us, when we were partners) with broken client sites and expensive rebuild bills. Teams also outgrow the content modelling quickly. Once you need complex relationships between content types, Prismic's flat structure becomes a bottleneck.
