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 10 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.app or *.firebaseapp.com URL, 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. 1. Paste your Firebase Hosting URL.
  2. 2. InstaDemo crawls the site and picks the pages worth showing — you can change the selection.
  3. 3. It writes a narration script from your real page content. You review and edit it, or paste your own script and it is read word for word.
  4. 4. It records the walkthrough, generates the voiceover, and returns a finished MP4.

Firebase Hosting demo videos — questions

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.
