Computer use: browser + desktop (Box)

Use this when a task needs a real GUI, not just a shell: logging into a web app, validating a rendered UI, controlling Chrome, testing an Electron app, or recording a demo. Box runs a full Linux desktop with Chrome; the Lux agent automates desktop/browser interactions and auto-records the session.

Recipe

box_id="$(box new --json | jq -r 'select(.event == "ready") | .id')"
# Get a live desktop stream URL (60fps WebRTC, or VNC over HTTPS on bad networks)
box desktop "$box_id" --json
# Automate a GUI goal with Lux (records to /home/user/lux-demos/)
box ssh "$box_id" -- "lux start 'log in to example.com and screenshot the dashboard'"
box ssh "$box_id" -- "lux run --max-steps 30"
box ssh "$box_id" -- "lux status"
