Watched
API-first website change detection with native MCP support
Point it at any URL, and it watches for changes — then notifies you via webhook, email, Telegram, or Discord. Most change detection tools (Distill, Visualping, Hexowatch) are UI-first dashboards. Great for individuals, terrible for automation. Watched is built for developers who want to integrate monitoring into code, CI/CD pipelines, or AI agents. Watched ships with a built-in MCP server. Any MCP-compatible AI agent can create, list, update, and delete watches using native tools.
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. 🎉
