Launch Team / Built With
Hey PH! I'm Vitaly, the solo dev behind Site Spy.
I built this because I was tired of manually checking websites for updates — price drops, job postings, documentation changes. Existing tools were either too expensive ($25-100/mo) or Chrome-only with clunky UIs.
Site Spy is different in three ways:
1. Element Inspector — Don't track the whole page. Click on a specific price tag, headline, or stock status and monitor just that element.
2. MCP Server for AI — Connect Site Spy to Claude, Cursor, or any MCP-compatible AI assistant. Your AI can monitor sites and summarize changes. No other monitoring tool has this.
3. Works everywhere — Chrome extension, Firefox add-on, and a full web dashboard that works on mobile too.
The free plan gives you 5 watches with no time limit. I'd love your feedback — what would make this more useful for you?
