A Hexowatch alternative with a simpler, more predictable setup

DiffHook is a Hexowatch alternative focused on doing change detection well — not offering a dozen different monitor types. Every detected change is delivered to Slack, email, Zapier, n8n, or your own app, on every plan, for a single flat price.

Hexowatch ships a broad range of monitor types from a single dashboard. DiffHook is narrower by design: it watches HTML pages, JSON APIs, RSS/Atom feeds, and sitemaps, and it delivers every change as a clean alert you can route anywhere. Fewer features, done more rigorously, with transparent pricing.

Why teams switch

Why teams switch from Hexowatch to DiffHook

Teams switching from Hexowatch usually want a simpler tool — fewer monitor types to pick from, clearer pricing, and alerts that work the same way on every plan.

  • One clear way to receive alerts — Slack, Discord, email, Zapier, n8n, or your own app — included on every plan.
  • Checks can run every minute on the paid plan, not just every 5 minutes on comparable Hexowatch tiers.
  • A developer API is included on every paid plan, so you can create, pause, or audit monitors from code.
  • Narrower monitor-type surface (pages, JSON APIs, RSS, sitemaps) — fewer sharp edges, clearer docs, and one consistent alert format.
  • Flat-rate team pricing — you don't pay more to unlock extra monitor types or alert channels.

Honest comparison

Where Hexowatch is still the better pick

Hexowatch's range of monitor types is genuinely broad — visual monitors, uptime checks, technology detection, WHOIS, and more. If your use case is 'catch a lot of different signals across a lot of sites from one dashboard' and you don't mind tier-gating, Hexowatch covers more ground than DiffHook. DiffHook is the call when you want fewer primitives, done more rigorously, on a flat price.

FAQ

DiffHook vs Hexowatch — common questions

How are DiffHook alerts different from Hexowatch's?
DiffHook sends every change as a clean alert that can be forwarded to Slack, Discord, email, Zapier, n8n, or your own app — on every plan, including the free one. Hexowatch supports similar destinations, but what's available depends on your tier.
How does pricing compare to Hexowatch?
Hexowatch's comparable paid plan starts around $14.99/month. DiffHook is $12/month and includes per-minute checks, every alert destination, and the developer API on the same flat rate. The DiffHook free plan covers 3 monitors at hourly checks.
Can I migrate my Hexowatch monitors to DiffHook?
For HTML pages, JSON APIs, RSS, and sitemap monitors — yes. URL, selector or path, interval, and destination all map cleanly. Niche Hexowatch types (WHOIS, technology detection, visual ping) don't have direct equivalents; teams often keep those in place and move the core change-detection monitors to DiffHook.
Does DiffHook work on modern JavaScript sites?
Yes. Every HTML monitor renders the page like a real browser — SPAs, client-rendered pages, lazy-loaded content. You can configure wait-for-selector or network-idle conditions per monitor when needed.
Does DiffHook support RSS and Atom feeds?
Yes, as a native monitor type. Paste a feed URL, set a check interval, and DiffHook sends an alert for every new entry — perfect when Hexowatch's RSS support isn't enough.
Do alerts work with Zapier, n8n, or Make?
Yes. Paste the platform's trigger URL as the DiffHook alert destination and change events flow straight into the automation. No extra setup required.
