Show HN: Reverse Engineer Web Apps (opens in new tab)

Hi HN! I’m Ray; Alex, Dima, and I built an open-source tool that turns web interactions into deterministic, repeatable flows you can invoke again via API or MCP: https://github.com/VectorlyApp/web-hacker

Why we built it: many web sites/apps don’t provide open APIs, and pure GUI automation is fragile. Our tool captures interactions, converts them into reliable, replayable flows, and exposes them programmatically so your integrations don’t depend on brittle screen-scraping scripts.

Quick demo: https://www.youtube.com/watch?v=YFVQSuiaWmM.

We’re three engineers coming from healthcare AI. We’d love feedback, issues, star(s), and feature requests. Happy to answer questions here.
