Turn your GitHub Pages site into a narrated demo video
Yes — InstaDemo makes demo videos for GitHub Pages apps. Paste your GitHub Pages 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.
GitHub Pages sites are usually docs or open-source projects — where a demo video does something specific: it stops maintainers from answering "what does this actually do" forever.
The problem with shipping on GitHub Pages
People land on the README, cannot tell in ten seconds what the project does, and leave. The docs are good — nobody reads that far.
What to know for GitHub Pages specifically
-
Both user sites (
username.github.io) and project sites (username.github.io/project) work. - A narrated video is the single highest-leverage thing you can put at the top of an open-source README — most visitors decide in seconds.
- Free-plan videos carry a small watermark, which is usually fine for a README; unlock a clean copy for $5 if you would rather it be unbranded.
How it works
- 1. Paste your GitHub Pages 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.

Can I embed the demo video in my GitHub README?
Yes. GitHub renders uploaded video files in Markdown, so download the MP4 and drop it in — or link out to the hosted share page.
Does it work with project sites in a subdirectory?
Yes. Both username.github.io and username.github.io/project URLs work.
Is there a free option for open-source projects?
The free plan gives you 5 demos a month. Free videos are watermarked; a one-time $5 unlock gets you a clean 1080p copy if you want it unbranded.
