Desktop app

Download Builder Wars

Your AI terminal, the game and X side by side in one window. The game can hand your agent a prompt, and nothing runs until you approve it. Once installed, the app keeps itself up to date. Everything also works in the browser; the app just keeps it in one place.

The AppImage runs on most distributions: make it executable, then open it, and it updates itself. The .deb and .rpm also register builderwars:// links and tell you when a new version is out.
