Analysis updated 2026-07-03
Add a complete backend with database, auth, and file uploads to a Next.js or Astro app by embedding bknd directly, without running a separate server.
Build a SaaS product with per-user data separation by deploying bknd on Cloudflare Workers with D1 as the database and R2 for file storage.
Replace Firebase in a React app by running bknd on Vercel or locally with a Postgres database and using the included React hooks.
Store AI agent state and tool results in a structured backend that exposes a built-in MCP server for AI assistant connections.

Figures from each repo's GitHub metadata at analysis time.
Requires Node.js 22.13 or later, the project is pre-1.0 and may introduce breaking changes between versions.
bknd is a backend toolkit that gives you database management, user authentication, file/media storage, and workflow automation all in one package. It positions itself as an alternative to services like Firebase or Supabase, but with a key difference: instead of sending your app's data to an external cloud service you cannot control, bknd runs wherever you want, including inside your existing web project. You can run it as a standalone server, embed it directly into a Next.js or Astro app, or deploy it to Cloudflare Workers, Vercel, AWS Lambda, and many other platforms. On the database side, bknd works with both SQLite (including Cloudflare's D1 variant) and Postgres (including Supabase and Neon hosted Postgres). For file storage, it connects to AWS S3 and compatible services, Cloudflare R2, Cloudinary, or the local filesystem. This adapter-based approach means you swap infrastructure pieces without rewriting your application logic. Once running, bknd exposes a REST API covering all its features. There is also a TypeScript SDK for JavaScript projects, plus React hooks for apps built with React. A visual admin interface is included for managing your data, configuring the backend, and handling users, all through a browser UI without writing code. The admin panel can be mounted at a route inside your existing React or Next.js app, so you do not need to run a separate service for it. bknd is built around web standards rather than proprietary APIs, which the project says makes it easier to move between hosting environments. All four main features (data, auth, media, flows) are modular, so you can use only what you need. The project also ships a built-in MCP server, which is a protocol for connecting tools like AI assistants to your backend data. The project is still pre-1.0, so the developers warn that backward-breaking changes may occur. Node.js 22.13 or later is required. Documented use cases include content management systems, SaaS products with multi-tenant user separation, AI agent state storage, prototypes, and general API-first apps.
An all-in-one self-hosted backend that gives your app a database, user auth, file storage, and workflow automation, deployable inside an existing Next.js project or on Cloudflare Workers and other serverless platforms.
Mainly TypeScript. The stack also includes TypeScript, Node.js, SQLite.
Setup difficulty is rated moderate, with roughly 30min to a first successful run.
