lsfr

Build distributed systems from scratch.

Progressive challenges to learn distributed systems and other complex systems by implementing them yourself.

Quick Start

Install:

$ go install github.com/st3v3nmw/lsfr/cmd/lsfr@latest

Or with Homebrew:

$ brew tap st3v3nmw/tap
$ brew install st3v3nmw/tap/lsfr

See lsfr.io for version pinning and other installation methods.

Start a challenge:

$ lsfr list             # List available challenges
$ lsfr init kv-store    # Create challenge in current directory
$ lsfr test             # Test your implementation
$ lsfr next             # Advance to the next stage

How it Works

Write code, run tests, get detailed feedback. Progress through stages as you build real systems.

If you're on GitHub, consider adding lsfr and lsfr-<language> (e.g., lsfr-go, lsfr-rust) as topics to your repository to share your implementation.
