Hey Product Hunt! 👋 I built Watched because I was tired of clicking through dashboards to monitor websites. Every developer has needed to watch a page for changes — competitor pricing, docs updates, job postings, stock availability. But the existing tools all want you to log into a browser, click around, and get email alerts. I wanted something I could curl. Watched is that: an API key, a POST request, and you're monitoring any page on the web. When something changes, you get the exact diff — not just "something changed" but what changed, line by line (or pixel by pixel with screenshot diffs). The MCP integration was a late addition but honestly it's become the killer feature — AI agents can now watch websites autonomously without any human clicking. Happy to answer any questions about the tech stack or how it works. Free tier available at watchedapi.com — no credit card needed. 🎉
