Your fallback dev environment, ready to go in the cloud.

If you can't install Claude Code locally (or just want to skip setup), click the button below to launch a fully configured environment in your browser.

This Codespace comes pre-loaded with:

• Claude Code — ready to authenticate and use
• Python 3.12
• Node.js (latest LTS)
• Go
• Git & GitHub CLI

Need something else? It's Ubuntu under the hood — sudo apt install anything you want, or just ask Claude Code to install it for you.

1. Click the green button above (or go to Code → Codespaces → New codespace on this repo)
2. Wait ~2 minutes for the environment to build
3. Open the Terminal panel at the bottom of the screen (Ctrl+` if it's not visible)
4. Type claude and hit Enter
5. You'll see a login link — click it, sign in with your Anthropic account
6. You're ready to code

• Make the terminal big. We'll be working in the terminal, not the editor. Drag the terminal panel up or double-click its title bar to maximize it.
• Web apps just work. If Claude Code starts a dev server, Codespaces will detect the port and show a notification with a link. Click it to open your app in a new tab. If you miss the notification, check the Ports tab next to the Terminal tab.
• Your Codespace persists. You can close the browser and come back later — your files and work will still be there. Codespaces auto-stop after 30 minutes of inactivity.
• Need a different language? Ask Claude Code: "Install Ruby and create a hello world script." It'll handle the apt install for you.

If you'd rather run Claude Code on your own machine:

• Mac/Linux: npm install -g @anthropic-ai/claude-code (requires Node.js 18+)
• Windows: Install WSL first (wsl --install), then install Claude Code inside WSL
