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 your first page free, forever.
