I built a web monitoring tool that watches any URL and posts changes automatically — solo, no funding, launching now
Hey IH — I've been building Canary for the past few months. It monitors any URL on the web and alerts you the instant something changes — prices, competitor features, APIs, docs, status pages, anything.
What makes it different: anomaly scoring (1-10 signal strength per change), AI summaries, collections for grouping URLs, and a fanout engine that publishes changes to X automatically.
I'm a solo founder with zero budget. Landing page is live, waitlist is open, and I literally just got the automated X crawler running today.
Would love feedback on the landing page and any thoughts on positioning.
