RVGEBRAIN is a Windows development environment for running command line coding agents, including Claude Code and Codex, side by side. It provides a shared workspace for monitoring agent activity, with status indicators for agents that are working, waiting for input, ready, or idle. Notifications alert users when an agent needs attention. Users can review agent edits in an editor, handle permission requests through cards, and submit follow-up messages through a composer that queues them until the relevant agent is ready. Sessions remain available across application restarts and can be replayed when users return. These features support workflows in which multiple coding agents work on separate tasks while a user monitors their progress and reviews changes. RVGEBRAIN runs on Windows 11 and starts agents that users install and access through their own accounts. The application does not include AI models or agent subscriptions, which are subject to the providers’ terms and pricing. The software offers a 30-day trial with all features, beginning on first launch. Google sign-in is required to start the trial.
