Show HN: I built a tool that watches webpages and exposes changes as RSS
I built Site Spy after missing a visa appointment slot because a government page changed and I didn’t notice for two weeks.
It watches webpages for changes and shows the result like a diff. The part I think HN might find interesting is that it can monitor a specific element on a page, not just the whole page, and it can expose changes as RSS feeds.
So instead of tracking an entire noisy page, you can watch just a price, a stock status, a headline, or a specific content block. When it changes, you can inspect the diff, browse the snapshot history, or follow the updates in an RSS reader.
It’s a Chrome/Firefox extension plus a web dashboard.
Main features:
- Element picker for tracking a specific part of a page
- Diff view plus full snapshot timeline
- RSS feeds per watch, per tag, or across all watches
- MCP server for Claude, Cursor, and other AI agents
- Browser push, Email, and Telegram notifications
Chrome: https://chromewebstore.google.com/detail/site-spy/jeapcpanag...
Firefox: https://addons.mozilla.org/en-GB/firefox/addon/site-spy/
Docs: https://docs.sitespy.app
I’d especially love feedback on two things:
- Is RSS actually a useful interface for this, or do most people just want direct alerts?
- Does element-level tracking feel meaningfully better than full-page monitoring?
