Show HN: Point it at your local dev server, get a demo video with AI voiceover

Hi HN, I'm Matt, one of the engineers behind Fly! We built Fly because we got tired of the gap between building features and showing them to people. Our team has been doing full-stack engineering for over a decade (most recently building Rownd, an authentication platform) and the one thing that never got easier was making videos. You finish a feature, you know it works, but showing it to someone means opening a screen recorder, figuring out what to say, re-recording when you stumble. So the just. doesn't happen. Fly is a CLI tool.
