Challenges with Prismic
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.
Benefits of ButterCMS
Key advantages
ButterCMS is one of those headless CMS platforms that genuinely nails the onboarding experience. We've seen content teams go from zero to confidently building pages and blog posts within a few hours, which is rare in the headless world. The dashboard is clean, the API explorer is thoughtfully designed, and the starter templates for popular frameworks mean developers aren't starting from scratch every time.
From an agency perspective, the standout quality is how little hand-holding editors need after launch. The interface is intuitive enough that marketers can create pages, manage blog content, and handle SEO metadata without constantly pinging the dev team. The built-in blog engine is a genuine differentiator. Most headless CMS platforms treat blogging as an afterthought, but ButterCMS was originally built around it, and it shows in the quality of the authoring experience.
The API performance is consistently fast, and the SDK support across languages like JavaScript, Python, Ruby, and PHP is solid. Their customer support team is also notably responsive and genuinely receptive to feature requests, which is something we don't often see from CMS vendors. For small-to-mid-sized projects where you need a reliable content API without overcomplicating things, ButterCMS delivers.
We'd particularly recommend it for teams that need a polished blog alongside structured page content, and who value simplicity over infinite extensibility. It's a CMS that knows what it is and does that thing well.
Exceptionally easy onboarding
Content teams can be productive within hours, not days. The dashboard is clean and the learning curve is one of the gentlest we've seen in headless CMS land.
Built-in blog engine
Unlike most headless platforms where you have to model blog content from scratch, ButterCMS ships with a purpose-built blog engine that includes categories, tags, authors, and SEO fields out of the box.
Fast and reliable content API
The read API is consistently quick with global CDN delivery. For content-heavy sites, the performance is solid and predictable.
No seat limits on any plan
Every plan includes unlimited users, which is genuinely unusual in this space. You won't get punished for growing your content team.
Responsive customer support
Their support team is quick to respond and genuinely open to feature requests. We've seen roadmap items added based on customer feedback, which builds real trust.
Strong SDK and framework coverage
Official SDKs for JavaScript, Python, Ruby, PHP, and more, plus starter projects for React, Next.js, Vue, Angular, and other frameworks that actually work out of the box.
Common questions
Prismic to ButterCMS migration FAQs
Answers to the most common questions about Prismic to ButterCMS migration
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.
How do we migrate content out of ButterCMS?
ButterCMS has a clean REST API, so pulling your content is straightforward. Blog posts, pages, and collections all export as JSON through their API endpoints. The main complexity is restructuring component-based page content for your target CMS, since ButterCMS components only work on pages and don't map 1:1 to other platforms. Media assets need to be downloaded from their CDN and re-uploaded. For a typical blog-heavy site with 200 to 500 posts, we complete the migration in 2 to 4 weeks.
Why do teams leave ButterCMS?
Content modeling flexibility is the top reason. Once projects grow past simple blogs and marketing pages, the 1,000 content field limit becomes a real ceiling. Components being restricted to pages (not collections or blog posts) forces awkward workarounds. Teams also feel the ecosystem gap, with fewer plugins, integrations, and community resources compared to larger platforms. The 2024 DNS incident that wasn't reflected on their status page raised trust concerns for teams running production sites.
What does ButterCMS cost compared to alternatives?
ButterCMS paid plans start at $71/month after a limited free tier. Every plan includes unlimited users, which is genuinely competitive. But the pricing jumps between tiers aren't proportional to what you get, and the content field limits apply even on expensive plans. By comparison, Sanity's free tier includes 3 users with 500K API requests, and you only pay more as your usage scales. For teams outgrowing ButterCMS, the cost of migration typically pays for itself within 6 months through better tooling and fewer workarounds.
