| description | Drive a real browser and Linux desktop in the cloud (computer use) — a full GUI with Chrome, a 60fps stream for visibility, and the Lux agent for automating clicks/typing/logins. Use for visual UI checks, logging into web apps, testing Electron apps, or any GUI task that can't be done over plain shell. Records demo videos automatically. |
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="$(box new --json | jq -r 'select(.event == "ready") | .id')"
box desktop "$box_id" --json
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 "$box_id" -- "lux status"
Why Box
- Real desktop + Chrome — does GUI work headless setups can't.
- Two stream modes — 60fps WebRTC (Moonlight) for quality, VNC-over-HTTPS for reliability on restrictive networks.
- Auto-recorded demos — every Lux run produces a video artifact.
Prereqs
curl -fsSL https://box.ascii.dev/install | sh, then box login "$BOX_API_KEY" --json.
Limits
EU-only; 100 active VMs soft cap. For massive parallel headless browser fleets, dedicated browser providers (Browserbase) scale further; Box is best when you need a full machine behind the browser.
