Quickstart

Install Cluster Build and start your first session in under two minutes.

Quickstart

1. Install

Install Cluster Build with a single command:

curl -fsSL https://assets.cluster.app/serve/cstatic-assets/releases/cli/install.sh | sh

This downloads the latest prebuilt binary for your platform and installs it to ~/.local/bin/cluster. Make sure ~/.local/bin is on your PATH.

Verify the install:

cluster version

2. Authenticate

Cluster Build uses Supabase for authentication. Log in with your Cluster account:

cluster auth login

Check your auth status at any time:

cluster auth status

3. Start a session

Run cluster in any project directory to start an interactive session:

cd my-project
cluster

The TUI opens and you can start chatting with the agent. Ask it to explore the codebase, fix a bug, or implement a feature — it has tools for reading and editing files, running commands, searching, and more.
