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 and you are done; pick a single element with the visual picker if you only care about one part of the page. Checks run in the cloud with a real browser — no extension or self-hosting.
