PocketBase: Open-Source Backend in One File
PocketBase is a self-hosted backend platform. An open-source backend in a single executable: SQLite database, realtime subscriptions, auth, file storage, and an admin UI included.
Why self-host PocketBase
A lot of small and personal projects do not need a distributed backend, they need one binary that handles a database, user accounts, and an API without becoming its own infrastructure project. PocketBase is built specifically for that case: download one executable, run it, and you have a working backend with an admin dashboard in under a minute.
What it does
PocketBase falls into the Backend as a Service category of self-hosted software. It bundles an embedded SQLite database, a realtime subscription system for live data updates, built-in user authentication (including OAuth2 providers), file storage, and an auto-generated REST API, all served from a single Go binary with an admin UI for managing collections and records without writing backend code.
Community traction
The project has 60.4k stars on GitHub and has become one of the go-to choices for developers who want a Firebase-like experience without the vendor lock-in, particularly for smaller projects where a full Supabase or Appwrite deployment would be more infrastructure than needed.
Deployment
PocketBase runs as a single self-contained binary with no external dependencies, which makes it trivially easy to deploy: copy the binary to a server and run it, or use the official Docker image if you prefer to keep it containerized alongside other services.
Alternatives
If PocketBase does not fit your needs, common alternatives include Supabase and Appwrite, both of which offer more built-in scalability and a broader feature set at the cost of a heavier deployment footprint, running as several containers rather than one binary.
Maturity
The current release is v0.39.10. The project is under active development with frequent releases, though it has not yet reached a 1.0 milestone, so reviewing release notes before upgrading a production deployment is worthwhile.

PocketBase is worth a look for any project where Supabase or Appwrite would be overkill. The single-binary deployment model is hard to beat for simplicity.
