Show HN: Runthru – open-source Interactive Demos (github.com)

I was looking for a tool to create interactive demos / walkthroughs for web based software. I was amazed that many companies charge well over $1000 per month for something pretty basic.

I made this which so far works well for me. You can point it at a site and either let AI (byo OpenAI or Anthropic keys) record and polish the whole thing or do it manually yourself (or a mixture of both).

Here is an example interactive demo:
