PocketBase

PocketBase packs the parts most small applications need into one Go binary you can drop onto a server. There is no separate database process, no auth service and no storage layer to wire together first.

You can take it two ways. Downloading a prebuilt executable and running the serve command gives a working backend immediately, with a JavaScript VM plugin enabled for extending it, while importing the Go package instead lets you add your own routes and business logic and still ship a single portable executable.

What the binary already contains covers most of a backend.

• Embedded SQLite: the database travels with the application and supports realtime subscriptions.
• Users and files: authentication and file management are built in rather than bolted on.
• Admin dashboard: a web interface for managing your collections and records comes included.
• REST-ish API: a straightforward HTTP surface that the official SDKs wrap for you.
• Client SDKs: JavaScript for browser, Node and React Native, Dart for web, mobile and desktop.

Building from source needs a recent Go toolchain, and static binaries compile without cgo for a long list of targets across Linux, macOS, FreeBSD and more. The maintainers warn that the project is still under active development and backward compatibility is not guaranteed before version 1.0.
