clstr CLI

Learn distributed systems by building them from scratch.

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

Quick Start

Start a challenge:

$ clstr list             # List available challenges
$ clstr init kv-store    # Create challenge in current directory
$ clstr test             # Test your implementation
$ clstr logs             # View interleaved logs from all nodes
$ clstr logs n2 n4       # View logs for specific nodes
$ clstr next             # Advance to the next stage

How it Works

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