PocketBase: A Realtime Backend in a Single File

Need a lightweight, open-source backend with realtime features, built-in auth, and a slick admin UI—all in one executable? Meet PocketBase.

What It Does

PocketBase is a Go-based backend that packs a surprising amount into a single binary:

• Embedded SQLite database with realtime subscriptions
• Built-in user auth, file storage, and admin dashboard
• Extensible via Go plugins or JavaScript
• Self-contained—no external dependencies or complicated setup

Think of it as Firebase’s open-source cousin, but with the portability of SQLite and the flexibility of Go.

Why It’s Cool

• "Just run it" simplicity: Download the binary, execute ./pocketbase serve, and you’ve got a full backend with a web UI.
• Realtime out of the box: Subscribe to database changes via WebSocket without writing boilerplate.
• Extendable: Add custom routes or logic in Go (or even JavaScript).
• MIT licensed: No vendor lock-in or hidden costs.

It’s perfect for prototypes, internal tools, or small projects where you’d rather build features than configure infrastructure.

How to Try It

1. Grab the latest release for your OS from the Releases page.
2. Run ./pocketbase serve—this starts the server + admin UI (default: http://localhost:8090).
3. Explore the API docs at http://localhost:8090/_/.

Prefer Go? Use it as a library:

package main

import (
	"log"
	"github.com/pocketbase/pocketbase"
)

func main() {
	app := pocketbase.New()
	if err := app.Start(); err != nil {
		log.Fatal(err)
	}
}

Final Thoughts

PocketBase isn’t for every use case (it’s not horizontally scalable, for example), but it’s fantastic for:

• Quick MVPs
• Jamstack backends
• Local-first apps
• Learning backend concepts without yak-shaving

If you’ve ever wished for a backend that “just works,” give it a spin. With 48K+ GitHub stars, it’s clearly scratching an itch.
