Canary is a solo-built URL monitoring tool that uses AI to detect and score website changes across competitor pricing, APIs, and documentation.

Automatically monitors any URL and sends alerts when changes are detected, with AI-powered summaries and 1-10 signal strength scoring

Built by a single developer with automated crawler running on GitHub Actions, posting real-time changes to Bluesky hourly and X daily

Features efficient URL deduplication architecture where one crawl serves multiple subscribers, optimizing resource usage
