The tool allows users to point it at a site and either let AI (using their own OpenAI or Anthropic keys) record and polish the demo, or create it manually, or a mix of both. The developer notes that many companies charge over $1000 per month for similar functionality, and the tool is offered as-is, not production-grade, with permission to extend, fork, or sell it.", "body_md": "I was looking for a tool to create interactive demos / walkthroughs for web based software.

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).\n\nHere is an example interactive demo:\n\n[https://runnit.io/demos/i-want-you-to-create-a-demo-of-from-...](https://runnit.io/demos/i-want-you-to-create-a-demo-of-from-the-dashboard-clickin/)\n\nDisclaimer: This is a tool which works for me and may work for you, it's not production grade software, use at your own risk. Extend it, fork it, sell it, it's up to you.\n\nComments URL: [https://news.ycombinator.com/item?id=49154806](https://news.ycombinator.com/item?id=49154806)\n\nPoints: 4\n\n# Comments: 0", "url": "https://wpnews.pro/news/show-hn-runthru-open-source-interactive-demos", "canonical_source": "https://github.com/marktolson/runthru", "published_at": "2026-08-03 12:23:20+00:00", "updated_at": "2026-08-03 12:54:55.316877+00:00", "lang": "en", "topics": ["ai-tools", "generative-ai", "developer-tools"], "entities": ["Runthru", "OpenAI", "Anthropic", "Hacker News"], "alternates": {"html": "https://wpnews.pro/news/show-hn-runthru-open-source-interactive-demos", "markdown": "https://wpnews.pro/news/show-hn-runthru-open-source-interactive-demos.md", "text": "https://wpnews.pro/news/show-hn-runthru-open-source-interactive-demos.txt", "jsonld": "https://wpnews.pro/news/show-hn-runthru-open-source-interactive-demos.jsonld"}}
