Changedetection.io is great if you want to run Docker and maintain a server. PageRadar is the fully managed version — AI noise filtering, Telegram alerts, a REST API and an MCP server, with nothing to host. Free tier included.

Changedetection.io means a Docker container, a host, updates, proxies and backups. PageRadar runs all of that for you — including anti-bot handling for JavaScript-heavy pages.
Self-hosted diffing alerts on every cookie banner and timestamp. PageRadar's AI only triggers on meaningful content changes, so you are not drowning in false positives.
Keep the developer ergonomics you like — a REST API — and gain an MCP server so an AI agent can create monitors and read changes directly. One API key for both.
No server costs, no maintenance time. Cancel anytime.
No credit card required. Monitor up to 5 pages free, forever.
