Claude CMS vs Sanity
Sanity is a flexible headless CMS — but your content lives in their Content Lake, you pay per user, and there's no server-side backend. Claude CMS is self-hosted, AI-managed, and £6.99/month flat.
Cloud content store vs self-hosted AI CMS
Sanity stores your content in their proprietary Content Lake — not in a database you control. Claude CMS stores everything in your own MySQL database on your own server. Claude manages the entire site through MCP tools; no Sanity Studio, no GROQ query language, no CDN costs.
Sanity
- ✗Content stored in Sanity’s Content Lake — a proprietary cloud store, not a standard database you can query directly.
- ✗Per-seat pricing on paid plans. Free tier limited to 3 users; Growth plan starts at $99/month.
- ✗Content-only CMS — no server-side PHP, no form handlers, no booking systems without a separate backend.
- ✗Requires learning GROQ — Sanity’s proprietary query language. Content can’t be accessed via standard SQL.
- ✗CDN bandwidth costs at scale — high-traffic image-heavy sites can face unexpected delivery charges.
Claude CMS
- ✓Content in your MySQL database on your server. Standard SQL. Portable. No proprietary store to migrate away from.
- ✓£6.99/month flat. Unlimited users, unlimited content. Claude is the editor — no per-seat cost.
- ✓Full PHP/MySQL backend. Claude builds forms, booking systems, payment handlers, and admin pages in the same session.
- ✓No query language to learn. Claude manages everything through natural language — no GROQ, no schema definitions to configure.
- ✓No CDN costs. Images live on your server. Bandwidth is whatever your hosting plan includes.
Can Sanity be self-hosted?
No — Sanity cannot be self-hosted. Sanity Studio (the editing interface) is open source and can be deployed on your own infrastructure, but your actual content always lives in Sanity’s hosted Content Lake. There is no on-premise or self-hosted version of the Content Lake, so your data, queries, and API access all depend on Sanity’s cloud — and its pricing.
What you can self-host
Sanity Studio only. It’s a React app you can deploy anywhere — but it’s just the editor UI. Every read and write still goes through Sanity’s cloud APIs.
What you can’t self-host
The Content Lake — the database that actually holds your content. There’s no Docker image, no on-prem licence, and no way to run it inside your own network.
The self-hosted alternative
Claude CMS is fully self-hosted: PHP and MySQL on any LAMP host you control. Content, images and backend logic all live on your server, managed by Claude over MCP.
If you’re searching for a self-hosted Sanity setup because of data residency, compliance, or cost-at-scale concerns, a genuinely self-hosted CMS solves the problem at the root. See our self-hosted CMS overview, or follow the migration steps below to move off the Content Lake entirely.
Feature comparison
Is Claude CMS the right Sanity alternative for you?
You’re hitting Sanity’s free-tier limits
Sanity’s free plan caps at 3 users and limited CDN bandwidth. Once you outgrow it, the Growth plan starts at $99/month. Claude CMS at £6.99/month is a self-hosted alternative with no tier ceilings or API rate limits.
You want standard SQL, not GROQ
Sanity uses GROQ — a proprietary query language only useful inside the Sanity ecosystem. Claude CMS uses MySQL. Your content is queryable with standard SQL and portable to any MySQL-compatible tool.
You need backend logic alongside content
Sanity is a pure content API — no PHP execution, no form handling. Claude CMS includes a full PHP/MySQL backend. Claude builds contact forms, booking systems, and payment handlers in the same conversation as your content.
✅ Choose Claude CMS if…
- You want your content in a standard MySQL database you control
- You need PHP backend logic alongside content management
- You’re a solo developer or small team without a per-seat budget
- You prefer managing via Claude chat over learning GROQ
- Predictable flat pricing matters more than enterprise CDN features
Consider Sanity if…
- Your team relies on Sanity Studio’s real-time collaborative editor
- You have a Next.js or React frontend consuming a structured content API
- You need GROQ’s flexible query syntax across deeply nested content types
- Enterprise-grade CDN delivery and global edge performance are critical
- Your workflow depends on Sanity’s large plugin and integration ecosystem
