Challenges with KeystoneJS

Key pain points

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.

Deployment complexity

Self-hosting is the only option, and the docs don't hold your hand. Getting Keystone into production requires real infrastructure knowledge, and the large Docker image sizes make it worse.

Small community and ecosystem

Compared to Strapi or even Payload, the community is much smaller. Fewer plugins, fewer tutorials, and slower support when things go wrong.

No built-in content workflows

There are no turnkey drafts, scheduled publishing, or approval chains. Keystone provides field primitives that can be assembled into publishing workflows, but you need to wire them up yourself.

Admin UI feels dated

The admin panel is functional but lacks the polish and UX of modern CMS interfaces. Non-technical editors often find it confusing and need more training.

No visual editing or live preview

There's no way for editors to see content in context before publishing. You'd need to build your own preview infrastructure, which is a significant engineering effort.

Scaling requires significant effort

Running Keystone under high traffic means managing session stores, reverse proxies, and server resources yourself. It doesn't scale as smoothly as cloud-native CMS alternatives.

Benefits of Sanity

Key advantages

You know where our bias' lies. We think Sanity is literally the best headless content management out there. The schema is code-based, so it can be easily versioned, scaled, and extended without a heap of third-party hoops to jump. Providing you build it with a solid foundation, which we always recommend Turbo Start Sanity, it's going to be the most valuable hub for content you can imagine.

It's got a very unique tooling called the Live Content API, which in simple terms means

when you press publish, its live.

No issues with caching, and a single API usage that scales perfectly with multichannel content delivery.

It also offers one of the best editorial experiences in the industry with Presentation and customizable content structures. We're obviously huge fans of it, and we've pivoted our business with it when we realised how ahead it is.

Multiplayer - multiple users editing the same blocks at the same time

Real time collaboration

You write, your teammate tags in, adds citations, and updates the same doc without stepping on each other. It’s the fastest way to ship content without the “who has edit access?” chaos.
