bknd runs directly inside your frontend app — no separate backend required. It works with Next.js, Remix, Astro, React Router. It also runs standalone on Cloudflare Workers, AWS Lambda, Bun, or Node.
It supports Postgres, LibSQL (Turso), D1, SQLite and has adapter-based storage. You get instant APIs, multi-strategy auth, media handling and a built-in Admin UI.
Curious what you’d build with it, feedback welcome!
(I haven't used a system like that. I'm intrigued by the idea of a backend that's just a database but it weirds me out not to have to write a layer that says who can read what. Exposing the database that nakedly feels super dangerous.)
In my (closed) product that exposes the database to the frontend, the "exposure" part has, effectively, row-level access control.[1]
[1] Also role-based using groups. I additionally mark the read-only queries as read-only and these are executed on a read-only replica.
