Hey Product Hunt! I'm Jesse. My coding agents open pull requests faster than I can check them out, and "tests pass" kept meaning less than I hoped. So I built RunThru to show me the feature actually running. It started as a hackathon project (4th of 80 at the OpenAI hackathon in NYC), and I've since rebuilt it end to end.

Comment /runthru on a pull request. RunThru opens the preview deployment in a real browser, uses the feature the PR changed, and films a narrated walkthrough with captions and chapters. Then a second model watches the video and says whether the feature works, with timestamps. About five minutes later it's all in one PR comment, plus a RunThru check next to your CI that you can require before merging.

A few things I'm proud of:

• It never invents. Narration is written only from what's on screen, and the reviewer checks every line against the picture.

• It caught a real bug for us: comments dated "62d ago" under a trial that had "just landed" on our staging site. Nobody told it to look, and no reviewer had noticed.

• It never pushes code or runs your code, and only runs when a repo member asks.

• Every video gets a share page you can link or email to anyone, no seat needed. It can also post each one to Slack with its verdict, or only the ones that need attention.

It's free for 5 videos a month, no card or API keys. After that it's about $1 a pull request: Pro is $29 a month for 30 videos, and the code FOUNDING takes 40% off for a year for the first 20 customers.
