Competitor Intelligence
Never be the last to know about a competitor move. Catch pricing changes, feature launches, A/B test variants, and product updates automatically — no browser tabs, no daily checking.
The challenge
The data you need is public.
The alerts are not.
Your competitors update their pricing pages, launch new features, run A/B tests, and quietly change their messaging — and none of it sends you an alert. By the time you notice, the market has already moved. The teams that win are the ones who see competitor changes first.
Why DiffHook
Monitor any competitor page
Pricing pages, feature announcements, changelogs, landing page variants, press rooms, careers — any public URL becomes an automatic alert.
CSS selectors cut the noise
Scope monitoring to exactly the element that matters — #pricing-table, .feature-list — so nav redesigns and cookie banners don't trigger false alerts.
See the exact diff, not just an alert
Every notification shows what changed: old text vs. new text. Your team acts on facts, not guesswork.
No scraping infrastructure to maintain
DiffHook handles polling, JS rendering, retries, and rate limit backoff. You get a webhook. No Puppeteer scripts to babysit.
How it works
Three steps to production
Point DiffHook at any URL
Add the competitor page — pricing, features, changelog, careers, about — with a CSS selector to focus on exactly what matters and filter out nav noise.
DiffHook polls on your schedule
Checks run every 1–60 minutes. Only meaningful content changes trigger an event — layout tweaks and cookie banners are ignored.
React before anyone else
Your webhook fires to Slack, n8n, Make, or your own API. Your team sees the exact diff within minutes — not weeks.
