Screenbox: Open-Source Virtual Desktops for AI Agents Built Entirely by Voice
What Screenbox Does
Screenbox creates isolated Linux desktops in Docker containers for AI agents. When you run multiple AI agents in parallel, they typically fight for the same screen, same files, and same browser. This causes problems like one agent downloading a file while another overwrites it, or one agent crashing Chrome while another loses its session.
Key Features
- Each agent gets its own isolated Linux desktop in Docker
- Full Chromium browser included
- Complete file system isolation
- Terminal access
- 21 MCP tools including screenshot, click, type, shell, and window management
- Everything a human can do at a desktop
Development Details
The project was built entirely using voice commands with Claude Code. The creator states: "I haven't seen a single line of code inside." It's currently running in production daily for both work and personal projects.
