I built bknd because I was tired of stitching together auth, file storage, and database APIs every time I started a new project. Existing solutions were either too hard to extend, too basic, or required a separate deployment.

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!

How do authentication and authorization work? Like Firebase?

(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.)

Yeah, I've never understood this. I can't think of any operation where I wouldn't want some backend logic in between. Firebase rules don't cut it.

Since you can embed bknd into any stack, and you can hook into system events, there are plenty of options to customize authorization according to your needs.
