DemoKit
Records CLI demo videos and refuses to save the file if the feature didn't work
DemoKit reads your routes, components and tests, plans a demo flow, then drives the real app in headless Chromium and films it in 4K. Three independent checks verify each step actually happened before it writes the file — no green checkmark for a feature that silently broke. The camera is Cap's zoom-and-spring engine ported as-is, driven by the recorded clicks rather than a model guessing where to point.

What holds up
- +Won't write the output file unless verification passes — no faked or stale demo videos
- +Plans from your actual routes, components and tests before opening a browser
- +Reuses Cap's proven camera (spring zoom, cursor) instead of a model deciding framing live
Mind the limits
- −Command-line tool — no GUI for people who don't want to touch a terminal
- −Ties output quality to Cap's camera engine, so you inherit its constants and quirks
