​
Requirements

macOS, Node 20 or later, and Claude Code, Codex, Cursor or OpenCode. Another agent takes two more steps: see Agents.
1

Set up

Setup asks which agents to connect, the export quality and whether pull requests get a demo, then downloads Chromium (about 190 MB) and connects Demoman, pre-approving its tools so they run without asking.
2

Restart your agent

Quit and reopen it, so it loads Demoman’s tools.
3

Ask for a demo

In your app’s repo:
Your agent drives Demoman’s browser out of sight, and the video lands in ~/Downloads.

Authentication

Record an app that needs you signed in.

Editing

Trim, cut and polish a take.

Data

What Demoman does, and does not do.
