Try Booley free in your browser

One click opens Booley with the PicoRV32 RISC-V CPU in browser VS Code, with simulation, synthesis and waveform tools already installed. Nothing to install, and nothing to pay.

1How the free demo works

The Codespace runs on your GitHub account's free monthly Codespaces allowance. The first launch takes 3-4 minutes while the container image builds.
The agent runs OpenAI's GPT-6 Luna through the Booley demo gateway, on the Booley maintainer's account. You run booley-demo-claim in a terminal: it shows a short notice, you agree and sign in with GitHub to get a demo token. The gateway logs usage numbers, never your prompts or code.
Each GitHub account gets $1 of demo usage per month.
START-HERE.md opens in the Codespace and walks you through the rest.

2Bring your own key

Your own Claude or ChatGPT account gives you a stronger model and no demo allowance. In the Codespace, open a terminal and sign in with one of:

BROWSER=none claude auth login
codex login --device-auth

Then switch Booley to your account (with both signed in, it picks Claude Code):

python -m booley.harness.incontainer_register

START-HERE.md has the step-by-step sign-in. To run Booley on your own machine instead, see the Install guide.
