The fastest way to know when any webpage changes. Paste a URL, choose your alert channel, and PageRadar does the rest — with AI noise filtering so you only get notified about changes that actually matter.
Most tools are either too expensive or too complex. PageRadar is neither.
Paste any URL — competitor pricing, your own site, docs, legal pages. We handle JavaScript-heavy pages, no config needed.
Our smart diff engine ignores ads, cookie banners, timestamps, and rotating content. Only meaningful changes get through to you.
Email, Telegram, Slack, or webhooks. Get a visual before/after diff the moment a real change is detected.
Drop any webpage URL — handles SPAs, JavaScript-rendered pages, and anti-bot measures via headless browser.
Daily checks on the free plan, every 5 minutes on Business. Match check frequency to how time-sensitive the page is.
See exactly what changed — added text in green, removed in red — delivered to your inbox or Telegram the instant it happens.
Know within minutes when a competitor changes their pricing — not days later when you notice lower sales.
