Bknd – Firebase alternative that embeds into any React stack
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…
In plain words
Bknd is a backend framework that integrates directly into React applications, eliminating the need for separate backend deployment. It bundles authentication, file storage, and database functionality with support for multiple databases including Postgres, SQLite, and LibSQL. The tool works within Next.js, Remix, Astro, and React Router, or runs standalone on serverless platforms. It includes automatic API generation, multi-strategy authentication, media handling, and an admin interface, designed for developers who want to avoid assembling multiple services for each new project.
