Stagehand — Presenter Console
Command 2 / 9Mode: human typingSpeed: medium
Start the Stack
Explain that the local Docker environment starts the API, database, and worker.
▶ Current Command
docker compose up -dNext Command
curl http://localhost:8080/healthWhat it does
A presenter console for command-line demos.
Keep your outline, notes, current command, and next command visible while Stagehand handles the boring and mistake-prone part.
⌥
Advance with hotkeys
Step through the demo without breaking flow. Copy, paste, or type the next command into whatever app is focused.
✦
Human typing mode
Stagehand can type commands like a real presenter, with speed control and subtle random pauses for a natural feel.
✓
Danger-aware by design
Risky commands can be flagged before they hit your terminal. Because live demos already have enough gremlins.
How it works
Write the script. Run the show.
Use normal Markdown headings for sections, fenced code blocks for commands, and optional metadata comments when you need extra control.
