Show HN: Screenbox – Self-hosted virtual desktops for AI agents

Screenbox gives AI agents their own isolated Linux desktop with a real Chromium browser, controlled via MCP.

I run multiple agents in parallel and they kept fighting over the same browser. Each desktop is a Docker container (~2GB RAM, no GPU). You can watch agents work in real time and take control when needed.

Open source (AGPL-3.0), self-hosted.
