About diffhook.com
DiffHook is a website change monitoring service that watches web pages, prices, policies, JSON APIs, sitemaps and RSS or Atom feeds, then sends an alert when something changes. Users point it at a URL and can track a full page or a single element, such as a price, a policy clause or a status label, using CSS or XPath selectors. Filters are designed to ignore layout and cosmetic changes, and higher plans add AI alert modes for price, availability, new items or a custom prompt.
Alerts can go to webhooks, email, Telegram, Discord, Google Sheets, Slack, Microsoft Teams, Jira and workflow tools such as n8n, Make and Zapier. Webhook delivery is signed with HMAC, retried automatically and recorded in a delivery log. A REST API is available on every plan.
The site describes use cases including tracking competitor pricing, following regulatory updates, watching vendor status pages, spotting prospect buying signals, protecting brand content and replacing in-house scrapers. Business features include SSO, role-based access, EU hosting on request, and private cloud, single-tenant or on-prem deployment for enterprise customers.
