The problem

You're flying blind
on changes that matter

Every day, critical pages update and you find out too late — or not at all.

📉

Competitor prices change overnight

Your rival drops prices Friday afternoon. You find out Monday morning when sales have already slumped.

🕵️

Your site changes without warning

A developer edits your landing page copy. An unauthorized redirect goes live. Your SEO drops and nobody knows why.

📋

Compliance docs update silently

A vendor's terms change. A regulatory page gets updated. You miss it — and it becomes your legal team's headache.

How it works

Running in 60 seconds

No setup wizard. No learning curve. Just paste, configure, and go.

1

Paste any URL

Drop any webpage — competitor pricing, your own site, government docs, API changelogs. We handle JavaScript-heavy pages too.

2

We monitor it

Our AI engine checks the page on your schedule and filters out noise — ads, timestamps, cookie banners. Only real changes get through.

3

Get alerted instantly

The moment something meaningful changes, you receive a visual diff via email, Telegram, or Slack. See exactly what changed, word by word.

FAQ

Common questions

Yes. PageRadar uses a real headless browser (Playwright) to fully render JavaScript — SPAs, React apps, dynamically loaded content. If you can see it in your browser, we can monitor it.
Our AI filter focuses on content that matters: text edits, price updates, new links, structural changes. It automatically ignores dynamic noise like timestamps, ad rotations, stock tickers, and cookie consent banners.
Yes. Use the browser extension to click-select any element, or paste a CSS selector in the dashboard. Monitor just a pricing table, a specific div, or a single paragraph — ignore the rest of the page.
We retry a few times before flagging a page as unreachable. You only get an "unavailable" alert after multiple consecutive failures, so brief outages don't flood your inbox.
PageRadar checks pages exactly as a browser would during a normal visit — no aggressive crawling, no bulk scraping. We follow the same access rules as any regular user.
One click in your account settings — no forms, no calls, no dark patterns. Your monitors stay active until the end of the billing period, then you drop to the free plan automatically.
