SleekCMS vs Sanity
The code-first content platform
Two code-first content platforms with different philosophies: Sanity gives developers a content lake and a query language; SleekCMS gives them one fetch, file-based models, and a site that ships itself.
TL;DR
Choose Sanity if real-time collaboration and GROQ-powered querying over a large content lake are central to your work. Choose SleekCMS if you want the same code-first, structured-content workflow with the frontend problem already solved - and flat pricing instead of per-seat.
Side by side
Both platforms treat content as structured data and developers as first-class users. They part ways on querying, editing, and what happens after the API.

| Query language | JMESPath filters | GROQ |
| GraphQL API | ||
| Image pipeline built in | ||
| The website itself | ||
| Integrated site builder + free CDN hosting | ||

GROQ is powerful. One fetch is simple.
GROQ is genuinely one of Sanity's best ideas - a query language that reshapes content on the way out: filter, join, project, and transform in a single expression. If your application needs precisely-shaped payloads from a large content lake, GROQ earns its learning curve.
SleekCMS's answer is to not make you query at all. One fetch returns the whole content graph - pages, entries, images, config - with references already resolved. For marketing sites, blogs, and docs, that single request usually is the entire integration. (A JMESPath filter is there when you want to slice the payload.)
Which is better depends on what you're building. A complex application with content woven through it: GROQ is a real asset. A website that needs its content, all of it, now: one fetch is hard to beat.
A Studio you build vs a CMS that's ready
Sanity Studio is a React application you configure in code - schemas as JavaScript, custom input components, your own deployment. That's real power, and code-first teams love it. It's also a real project: the Studio is software you build and maintain alongside the site itself.
SleekCMS keeps the code-first spirit without the second codebase. Models are plain .model files that sync from your editor via npx @sleekcms/sync - version-controlled, AI-friendly (context files for Claude Code and Copilot ship in the box), and instantly reflected in an editing UI you never had to build. Views are EJS templates in the same workspace.
Editors get a ready CMS on day one. Developers keep files, sync, and AI-assisted local work. Nobody maintains a second application.
Pricing at a glance
