PageRadar
PageRadar watches web pages and alerts you by email, Telegram, Slack, webhook or RSS when they change, with a visual diff and a one-line AI summary of what changed. REST API and MCP server included from $7/mo; free plan for 5 pages.
AI use When a monitored page changes, an LLM (via an API provider) reads the diff, writes the one-line summary shown in the alert and labels the change as price, availability, content, layout or noise, so noise can be filtered out. AI agents can use the hosted MCP server to list, create, inspect and delete monitors and to read recent changes with their summaries.
PageRadar checks the pages you choose on a schedule (daily on Free, down to every 5 minutes on Business) in a real cloud browser, compares each snapshot with the previous one and alerts you only when something meaningful changed. Every alert links to a visual diff with additions and removals highlighted, plus a one-line summary of the change. Watch a whole page or narrow it to one element with the visual picker or a CSS selector. Alerts go to email, Telegram, Slack, signed webhooks or RSS, and everything is scriptable through the REST API and the MCP server.
