We are the ButterCMS to Agility CMS migration experts

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.

Agility CMS is one of the few headless CMS platforms that genuinely tries to bridge the gap between developer freedom and editor autonomy. The standout feature is built-in page management, something most headless CMS tools completely ignore. Editors can create and manage pages, control the sitemap, handle SEO fields, and arrange modular components on pages without needing a developer to wire everything up. That alone saves us a ton of back-and-forth on client projects.

The Next.js integration is solid and well-maintained. The SDK handles page routing, preview mode, and image optimization out of the box, and getting a starter site running takes minutes rather than hours. The content modeling interface is intuitive enough that even non-technical clients can understand and extend models without hand-holding, which is rare in the headless space.

Support is genuinely excellent. The team is small enough that you get real humans who know the product inside out, not a ticket queue that disappears into the void. For agencies that need to move fast and hand projects off to client teams, that responsiveness matters. The API request limits are generous too, with high request allowances across all plans, so you're not constantly worrying about overage charges like you would with some competitors.

We also appreciate that Agility takes a pragmatic approach to headless. It doesn't try to be everything, but it does the core CMS job well and stays out of your way when you need to build custom functionality around it.
