Show HN: I built a tool that watches webpages and exposes changes as RSS
7 by vkuprin | 3 comments on Hacker News.
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://ift.tt/Ll1nIER... Firefox: https://ift.tt/dMzDfis Docs: https://ift.tt/wPnAxsa 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?
