Most Distill.io monitors live in a browser extension — close the browser, stop monitoring; cloud monitors are capped by plan. Changedetection.io needs a Docker server you maintain. PageRadar runs in the cloud 24/7, no matter what device you use.
Distill keeps AI features on paid plans and Changedetection.io needs your own LLM key. PageRadar's noise filter is on every plan and skips ads, cookie banners and timestamp updates.
Paste a URL, pick your alert channel (email, Telegram, or Slack), and you're done. No extension to install, no YAML config files, no reverse proxy setup.
No lock-in. Cancel anytime. No servers to manage — ever.
