Use cases
- GUI application testing — interact with desktop apps built or modified by an agent
- Browser testing — verify web applications in a full browser environment inside the sandbox
- Visual debugging — inspect graphical output, rendered documents, or UI state
- Agent observation — watch an AI agent perform automated desktop interactions
How it works
Sandboxes support VNC through a set of pre-installed packages (Xvfb, xfce4, x11vnc, noVNC) that provide a headless desktop environment with browser-based access. When VNC is enabled:- Start a run with VNC enabled on a cloud sandbox
- Open a browser-based VNC viewer to see the sandbox desktop
- Interact with the desktop using mouse and keyboard — or watch an agent automate it
