We are the KeystoneJS to ButterCMS migration experts

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.

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.
