2 Best Open Source Sanity Alternatives

Why choose an open-source Sanity alternative

Sanity stores content in a hosted content lake with pricing tied to seats and API usage, so a high-traffic site can see its API request costs rise independent of how much content it actually manages. Self-hosted headless CMS options move that content into a database you manage:

• Data ownership: content lives in a database you control instead of a hosted content lake owned by a third party.
• Self-hosting: run the CMS and its database on your own infrastructure, giving you direct control over backups and uptime.
• Cost: avoid per-seat and API-request pricing tiers that scale with traffic rather than with the actual amount of content stored.
• Customization: modify the admin panel, content models, and API behavior directly in code instead of working within a hosted platform's constraints.
• Avoiding lock-in: standard databases like Postgres or MongoDB replace a proprietary content store, so migrating away later means a database export rather than a vendor-specific data dump.

What to look for

Check content modeling flexibility for custom fields and relations between content types, whether the API is REST, GraphQL, or both depending on your frontend's needs, how usable the admin panel is for non-technical editors who will manage content daily, whether the CMS is standalone or tied to a specific frontend framework, and how media and asset management, including image resizing on the fly, are handled.

How the top Sanity alternatives compare

• Strapi is a standalone JavaScript and TypeScript headless CMS with both REST and GraphQL APIs, usable with any frontend framework, which makes it a fit for teams running multiple frontends against one content backend.
• Payload is a fullstack Next.js framework that doubles as a headless CMS, generating a TypeScript backend and admin panel directly from your schema, which suits teams already committed to Next.js for their frontend.

Strapi runs as a separate service from your frontend application, so it can serve content to a mobile app, a marketing site, and a web app at the same time. Payload's tighter coupling to Next.js means less infrastructure to run when your frontend and backend already live in the same repository.
