What is DiffHook?

DiffHook is a real-time website change monitoring service that watches the pages, prices, policies, and APIs your business depends on. It alerts the people or systems that need to act the instant something changes. With over 10 million change events delivered, DiffHook helps teams never miss a competitor price move, stay ahead of regulatory updates, and know before customers do about vendor status changes.

Who it's for

• Sales and revenue teams – who need to catch competitor pricing and packaging changes within minutes to protect win-rates and deal velocity.
• Legal and compliance professionals – who must track regulatory updates, policy filings, and compliance portal changes continuously to avoid fines and audit failures.
• Operations and engineering teams – who monitor vendor status pages, certifications, and SLAs to alert on-call before the first support ticket lands.

Key features

Watch anything that matters

Track any page, any feed, or any API. DiffHook lets you monitor a full site or zoom in on a single element like a price, a policy clause, a status badge, or an availability flag.

Alert only on signal

Smart filters cut through layout changes and cosmetic noise, so every alert is meaningful and none are wasted. Your team gets notified only when something actually changes.

Route it anywhere

Send changes to Slack, Discord, Notion, Airtable, Linear, or any webhook URL. No code is needed for common jobs, and a full API is available when you need custom workflows.

Trust it at scale

Signed, reliable delivery with automatic retries ensures you never miss an alert. Complete change history, SSO, role-based access, and EU hosting are available on request.

What stands out

Know the moment the web changes before it costs you.

DiffHook turns silent web changes into first-class events your team can see, measure, and act on. Instead of discovering a competitor price cut or a regulatory update days late, you get structured alerts in your existing tools within seconds. The combination of smart noise filtering, reliable delivery, and integrations with over 10 million change events delivered makes it a drop-in replacement for brittle in-house scrapers.

Worth checking out if…

You rely on external websites for competitive intelligence, regulatory compliance, or vendor status monitoring. DiffHook is especially valuable if your team has ever discovered a critical web change through customer tickets or missed a pricing move that cost you deals. With plans starting at free for 5 monitors and daily checks, it's easy to start without commitment.
