Profile

I built PulseWatch as a solo dev because I was tired of writing CSS selectors to monitor websites for changes.It uses GPT-4o to analyze page screenshots and suggest what to track — just point and click. When something changes, you get a plain-language summary instead of a raw diff.Tech stack: .NET 8, Flutter (web + iOS + Android), PostgreSQL, Railway + Vercel.Free tier: 2 monitors with daily checks.Demo: https://youtu.be/2SKgV4QqtNgHappy to answer any questions!
