DemoFly — Demos that record themselves
Hi HN, I'm Matt, one of the engineers behind DemoFly! We built DemoFly 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 demo 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 demo just...doesn't happen. DemoFly is a CLI tool. You point it at whatever you're…
DemoFly — Demos that record themselves launched on March 10, 2026 with 12 votes, #1,060 of 23,380 launches that month and more than 90% of that year's launches.
What it does
DemoFly turns what you're building into a professional demo video automatically. No screen recording, no scripting, no editing. Point it at a branch, a local dev server, or a new feature. DemoFly's AI navigates your product, captures the key flows, adds natural voiceover, and produces a polished video ready to share. CLI-first, built for dev workflows — generate demos from your terminal or CI pipeline. Edit and share from the dashboard. Free tier includes every feature.
DemoFly generates beautiful product demos from your codebase. No recording. No talking. No clicking.

ScreentellJan 2026 · screentell.com · ▲164I’m an indie dev, and every time I launch or ship anything, there’s this familiar mini-hell: “now I need to record a decent demo…” You probably know the drill: - install yet another screen recorder - mess with audio input / system audio - accidentally capture your messy tabs or notifications - re-record because you forgot to hide something sensitive - open a separate editor just to crop, zoom, or add a simple arrow After doing this a few too many times, I realized I was spending way more time fighting tools than making the actual demo. And most of my needs were pretty simple: short…
