Challenges with Tina CMS
Key pain points
Tina's biggest limitation is that it's fundamentally tied to the React ecosystem. If you want visual editing, you need a React-based framework like Next.js. Basic content editing works with Astro, Hugo, SvelteKit, and others, but the flagship visual experience is React-only. There's been talk of Vue support for years, but nothing has materialised. This is a hard blocker for agencies like us that work across different tech stacks. The platform has also had a notable history: SSW acquired the project in May 2024, and a security breach in late 2024 involved compromised AWS keys via the CI/CD pipeline. These events, combined with the relatively small community, are worth weighing when evaluating Tina for long-term enterprise projects.
On the practical side, developers report frustrating instability in the dev environment. The admin interface can break without any changes to your codebase because it depends on externally loaded assets that update independently. Error handling is weak — forms fail to save silently, and the GraphQL layer doesn't surface errors cleanly. Self-hosting removes the TinaCloud dependency but comes with its own gaps: no search functionality, no Git LFS support, and reference fields can timeout on large collections.
The editing experience, while impressive in demos, can feel fragile in production. Multiple developers have reported losing work in the editor, and features like branch-based editing are locked behind paid tiers. For agencies managing multiple client projects, the React-only constraint and relatively small community (compared to Sanity, Strapi, or Contentful) mean fewer resources, fewer integrations, and more time spent solving problems yourself.
Visual editing limited to React
TinaCMS supports many frameworks including Astro, Hugo, Jekyll, SvelteKit, and Nuxt for basic content editing. However, the visual/inline editing experience, which is Tina's main selling point, only works with React-based frameworks like Next.js.
Unstable development environment
The dev server can break unpredictably because it loads external assets that change independently of your codebase. This makes local development feel unreliable and hard to debug.
Poor error handling and silent failures
Forms can fail to save without any visual indicator, and GraphQL errors aren't surfaced clearly. Losing work without warning is a real risk, especially for content editors.
Branch editing requires paid tier
Multi-branch support isn't available out of the box — it's locked behind the paid editorial workflow feature. You can't test content changes in deploy previews without paying up.
Self-hosting gaps
The self-hosted backend lacks search functionality, Git LFS support, and pagination on reference fields. Large collections can cause network timeouts.
Small ecosystem
Compared to established players like Sanity or Contentful, Tina has a smaller community and fewer plugins. Since the SSW acquisition in May 2024, the project has been actively maintained with regular releases, but the ecosystem is still catching up.
Benefits of Prismic
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.
Seamless publishing experience
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.
Common questions
Tina CMS to Prismic migration FAQs
Answers to the most common questions about Tina CMS to Prismic migration
How do we migrate content out of Tina CMS?
Tina stores content as markdown and MDX files in your Git repository, which makes extraction the easiest part of any CMS migration we do. Your content is already files on disk. The work is in transforming those markdown files into the structured format your new CMS expects. Rich text blocks, custom components embedded in MDX, and frontmatter fields all need mapping. For a blog or docs site with 100 to 500 pages, we typically complete the migration in 2 to 4 weeks.
Why are teams leaving Tina CMS?
Three issues come up repeatedly. First, the React-only constraint for visual editing blocks teams that want to use Astro, SvelteKit, or other frameworks. Second, the development environment is unstable. The admin interface loads external assets that update independently of your codebase, so it can break without you changing anything. Third, the 2024 security breach involving compromised AWS keys shook confidence in the platform's operational maturity. Teams with enterprise compliance requirements found that hard to overlook.
Is it worth self-hosting Tina instead of migrating away?
Self-hosting removes the TinaCloud dependency, but it introduces its own gaps. There's no search functionality, no Git LFS support, and reference fields timeout on large collections. If you're already frustrated with Tina's instability, self-hosting adds more operational burden rather than solving the root problems. We've found that teams considering self-hosted Tina are usually better served by migrating to a platform with proper managed hosting and a more mature editorial experience.
How much does Prismic cost?
Prismic has a free plan for 1 user with limited API calls. The Starter plan is $7/month per user for small teams. The Small plan is $150/month for up to 25 users with more locales and API bandwidth. Medium is $500/month. 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.
