About this tool

PageRadar watches web pages and tells you when they change — by email, Telegram, Slack, webhook or RSS — with a visual diff of exactly what changed and a one-line summary in the alert. Paste a URL, or pick a single element with the visual picker. Typical uses: a competitor's pricing page, back-in-stock and price drops, job or grant listings, supplier terms. REST API, MCP server, signed webhooks and RSS are included from the $7 plan. Free plan: 5 pages, daily checks.
