Best if you just want to see how it works
Debug in context
See the UI, errors, and network requests together
When something breaks, it's rarely obvious why. Replay shared sessions, inspect requests, and trace errors, all in one place.
Like the Network tab in DevTools, but for someone else's session.
Replay sessions
Watch what users actually saw after you share a localhost app.
Trace errors
Tie console issues back to the exact click, route, and sequence that caused them.
Where This Is Useful

DemoTape is built for any moment where sending a link is faster and more revealing than writing an explanation.
Pull Request
Let reviewers try your changes instead of guessing from code.
Bug Reports
Stop writing steps to reproduce. Just show what happened.
Product Demos
Let people use your app, not just watch it.
Client Or Stakeholder Feedback
See exactly where they get stuck.
From local to shareable in seconds
Run one command

The terminal animation types demotape, detects local services, prints a public URL, and shows that the visitor session is being recorded.
