PocketBase

PocketBase provides a single‑file, self‑hostable backend written in Go that bundles an embedded SQLite database with realtime subscriptions, file storage, user authentication, and an administrative UI. It exposes a simple REST‑ish API and can be run directly as a prebuilt executable or compiled into a statically linked binary, making it suitable for SaaS, mobile, or desktop applications that need a lightweight server without external services.

Developers can interact with the API through official JavaScript and Dart SDKs, which support common operations such as querying collections, creating records, and subscribing to live updates. The platform also allows custom business logic by embedding PocketBase as a Go library, enabling developers to extend routes and handlers while still delivering a single portable executable.

The project is open source under the MIT license, offers a free tier without subscription requirements, and is maintained as a stable, actively developed tool for building full‑stack applications with minimal infrastructure overhead.
