About DiffHook

DiffHook is a real-time website change monitoring platform that enables teams to instantly detect and act on web changes. It tracks any URL, JSON API, RSS/Atom feed, sitemap, or specific page element (using CSS/XPath selectors), then delivers structured alerts via webhook, Slack, Discord, Telegram, email, Microsoft Teams, Jira, Google Sheets, and more. Powered by Cloudflare AI, DiffHook filters out cosmetic noise and highlights only meaningful changes. With polling intervals as fast as 1 minute on paid plans and end-to-end alert delivery under 5 seconds, it is built for automation-first users who need reliable, API-native event triggers. DiffHook offers transparent, usage-based pricing starting at $12/month for the Starter plan, along with a free tier. Common use cases include competitor price monitoring, regulatory compliance tracking, vendor status page surveillance, sales intelligence, brand protection, and replacing brittle in-house scrapers. Integrations with n8n, Make, Zapier, Notion, Airtable, and Linear allow seamless workflow automation. Over 10 million change events have been delivered. DiffHook is operated by KupaLabs FZCO based in Dubai, UAE.
