Stop manually refreshing pages. PageRadar automatically monitors website changes and sends you a visual diff the moment something meaningful updates — via email, Telegram, or Slack.
One page is easy. Five pages is manageable. Fifty pages is a full-time job.
Your rival drops their price Friday evening. You find out Monday when sales have already dropped. With PageRadar, you know within 5 minutes.
A developer edits your landing page. An unauthorized redirect goes live. Monitor website changes on your own properties to catch issues before customers do.
Vendor contracts, API terms, and compliance docs get updated without announcement. Monitoring them manually is impossible at scale.
Paste the webpage URL — competitor pricing, your own site, government docs, API changelogs. Works on JavaScript-heavy pages via headless browser.
Daily on the free plan. Every 5 minutes on Business. Match frequency to urgency — pay only for what you need.
When a real change is detected, you get a before/after diff — added text in green, removed in red — sent to your email, Telegram, or Slack.
Your rival drops their price Friday evening. Know within 5 minutes — not Monday morning when sales have already slipped.
Stripe, AWS, or a key supplier silently updates their terms. Get alerted before it affects your business.
Track property listings, rental prices, and inventory pages. Move fast when something new appears.
Monitor dream companies for new roles. Apply on day one, before the posting gets buried.
A developer edits your landing page without telling you. Catch unauthorized changes before customers do.

Email, Telegram, Slack, and webhooks. Get notified wherever you already work.
Click any element on a page to start monitoring it. Works on Chrome and Firefox.
