bknd is an open-source, embeddable TypeScript backend for JavaScript applications. Instead of running as a separate hosted service, it lives inside your app: you define data entities, authentication, media storage, and scheduled workflows in code, and bknd serves them through generated REST endpoints plus a built-in admin dashboard. It suits solo developers and small teams who want backend primitives without operating a second service or accepting vendor lock-in.[1][2]
Quick verdict
bknd fits JavaScript developers building content-driven apps, MVPs, or AI agent backends who are comfortable owning their database and infrastructure. Its strength is embeddability: the same codebase runs on Node, Bun, Deno, Cloudflare Workers, Vercel, or AWS Lambda with SQLite locally and Postgres in shared deployments. The material constraint is maturity and operations: bknd is pre-1.0 with no backward-compatibility guarantee, and documented sync and cloud hosting are still planned, so teams needing a managed service or a no-code console should choose Firebase or Supabase instead.[1][2][3]
Key features
Code-defined data model Entities declare typed fields including text, number, boolean, date, JSON, and enum, plus relation fields, with required, unique, fillable, and hidden attributes, sortable and filterable flags, indexes, and per-entity OpenAPI exposure.[1]
Generated REST plus OpenAPI Every entity becomes a validated REST endpoint with queryable, paginated reads, and the schema produces OpenAPI documentation that client tooling can consume.[1][2]
Built-in authentication Password and OAuth strategies come with role-based permissions, so routes and records can be restricted without wiring a separate identity provider.[1]
Pluggable media storage File handling works through adapters for AWS S3 and S3-compatible stores, Cloudflare R2, Cloudinary, the local filesystem, and the browser Origin Private File System.[1][2]
Scheduled flows Time-based workflows run inside the same backend, covering jobs like publishing, cleanup, and notifications without a separate queue service.[1]
Embeddable admin dashboard A visual admin UI for data, auth, media, and flows ships with the package and mounts inside frameworks such as Next.js, React Router, Astro, Vite, and Waku.[1][2]
Run-anywhere runtimes Support spans Node.js 22 and newer, Bun, Deno, browsers, Cloudflare Workers and Pages, Vercel, Netlify, Deno Deploy, AWS Lambda, and similar edge or serverless targets.[1]
SQLite to Postgres portability Local development can use SQLite variants including LibSQL, Cloudflare D1, and Durable Objects SQLite, while shared deployments move to Postgres, Supabase, Neon, or Xata behind the same backend code.[1]
Who will love it
Framework-embedded teams If your backend must live inside a Next.js, Astro, or React Router app and deploy to the edge, bknd removes the second service entirely.[1][2]
Lock-in-averse builders Adapter-based drivers with direct access to the underlying database and storage mean you can leave without a migration cliff.[1]
API-first TypeScript shops A typed SDK plus OpenAPI output gives client developers a contract to build against from day one.[1][2]
Who should avoid it
Non-technical operators Everything is code-defined and self-run; teams wanting a clickable console with managed scaling should pick a hosted backend-as-a-service.[1]
Stability-first enterprises The project warns that full backward compatibility is not guaranteed before a 1.0 release, which makes bknd a poor fit where upgrade churn has contractual or compliance cost.[1][2]
Teams waiting on managed sync Sync and cloud hosting are documented as planned rather than available, so teams depending on bknd-hosted infrastructure should adopt only when those ship; today you operate the database yourself.[1]
Fit and alternatives context
Firebase alternative without the platform bknd describes itself as a lightweight Firebase and Supabase alternative, but it is a package you embed and operate, not a managed platform; the catalogue records Firebase as its incumbent alternative.[1][2]
Self-run operations assumed Standalone, Docker, serverless, and edge deployments are documented, while backups, scaling, and uptime remain the adopter's responsibility with no vendor status page.[1][2]
