From ButterCMS to Contentful
Key pain points
Where ButterCMS starts to show cracks is when projects grow beyond its comfort zone. The content modeling is adequate for straightforward use cases, but it lacks the depth and flexibility of platforms like Sanity or Contentful. Components are only available for pages, not collections or blog posts, which creates frustrating inconsistencies when you're trying to build a cohesive content architecture. The 1,000 content field limit, even on expensive plans, can become a real ceiling for ambitious projects.
The platform's smaller ecosystem is a double-edged sword. While anyone who knows JavaScript can work with the API, you won't find the same depth of community resources, plugins, or third-party integrations that larger platforms offer. Media management is also noticeably behind, with no bulk upload capability and limited asset organisation tools. For agencies managing multiple client sites, these paper cuts add up quickly.
There have also been transparency concerns. In 2024, a DNS incident affected thousands of sites using ButterCMS, but their status page showed no downtime. That kind of communication gap is a red flag for any team relying on a third-party CMS in production. The pricing, while competitive on the surface, can feel steep for smaller teams once you move past the limited free tier, and the jump between plans isn't always proportional to what you get.

Limited content modeling flexibility
Components are only available for pages, not collections or blog posts. This creates awkward workarounds when you need consistent structured content across different content types.

Content field limits on all plans
Even the most expensive plans cap you at 1,000 content fields. For complex, multi-locale projects this ceiling arrives faster than you'd expect.

No bulk media upload
The media library only supports single-file uploads with limited organisation tools. Managing assets across a large site becomes tedious quickly.

Small ecosystem and community
Compared to Contentful or Sanity, the community is tiny. Fewer plugins, fewer tutorials, and fewer developers with direct experience means more problem-solving on your own.

Transparency concerns around incidents
In 2024, a DNS incident reportedly affected sites using ButterCMS, but limited public acknowledgement on their status page raised concerns about transparency. The details are difficult to verify independently.

Pricing jumps between tiers
The free tier is very limited, and paid plans start at $71 per month. For small projects or startups, the cost can be hard to justify when alternatives offer more generous free tiers.
Key advantages
With over 42.9% market share and more than 14,000 companies using it, Contentful is one of the most popular headless CMS choices among our customers. And why not?
It's built for structured freedom, which lets you create once and reuse forever from its huge repository. Meaning, no more copy-paste déjà vu or hunting through a maze of components. It's also one of the only CMS with first-party support for A/B testing and personalization. The plugin ecosystem is vast, and it keeps developers happy and content teams nimble with SEO, internationalisation, validation, and more.
And for the editors who like to see it as they build it, the live side-by-side preview makes every change visible in real time.

API-first design
Contentful was built for APIs from day one, which means your content plugs cleanly into apps, websites, and mobile.

Developer-friendly flexibility
Schemas, content models, and references can be tuned however you like. If your stack is anything beyond “cookie-cutter,” Contentful won’t get in your way.

User-friendly interface
Editors enjoy using it. Clean UI, quick search, structured fields, and no “where does this go again?” confusion.

Extensive integration capabilities
Plug in analytics, eCommerce, automation, and translation. Contentful plays nicely with almost anything. And if something isn’t supported yet, you can wire it up yourself without hacking the platform apart.

High scalability
From a tiny blog to a fire-hose of global traffic, Contentful easily scales. You can completely avoid surprise outages, or “please hold while the CMS catches up.”

Cloud-based architecture
You don't have to install, patch, or maintain anything. It’s fast, globally distributed, and always up to date. Your content team can ship from anywhere without a DevOps babysitter.
