Turn your Firebase app into a narrated demo video
Yes — InstaDemo makes demo videos for Firebase Hosting apps. Paste your Firebase Hosting URL and it records a walkthrough, writes the narration script and generates the voiceover automatically. No screen recorder, no editing, no voice talent. The free plan includes 5 demos a month; Pro is $19/month for 50 at 1080p with no watermark.
Firebase-hosted apps are a regular InstaDemo input, usually single-page apps where the routing needs to behave properly on the way in.
The problem with shipping on Firebase Hosting
The app is live on a free tier and works fine. There is still nothing you can paste into a tweet that shows what it does.
What to know for Firebase Hosting specifically
-
Use the
*.web.appor*.firebaseapp.comURL, or your connected custom domain. - SPA rewrites are followed as a visitor would experience them, so deep links and client-side routes render normally.
- Firebase Auth in front of the app means a URL-only recording captures the sign-in screen — record with Autopilot instead.
How it works
- 1. Paste your Firebase Hosting URL.
- 2. InstaDemo crawls the site and picks the pages worth showing — you can change the selection.
- 3. It writes a narration script from your real page content. You review and edit it.
- 4. It records the walkthrough, generates the voiceover, and returns a finished MP4.

Does InstaDemo handle Firebase single-page apps?
Yes. Recording happens in a real browser, so rewrites, client-side routing and deep links behave exactly as they do for a visitor.
What about apps gated by Firebase Auth?
A signed-out visitor sees the login screen and so does the recorder. Use the Autopilot Chrome extension to capture the signed-in flow.
web.app or firebaseapp.com — does it matter?
No. Both work, as does a custom domain.
