Your webhook failed 6 days ago. You just found out.
Webhooks fail silently. The provider sent the payload, your endpoint returned 200, but your handler stopped processing it three versions ago. Nobody noticed until a customer complained.
Hooklistener monitors watch your endpoints for inactivity — not just uptime. If expected webhooks stop arriving, you get an alert before your customers notice.
Know when webhooks go silent
Monitors are attached to your Debug Endpoints. Configure the threshold, pick your alert channels, and stop worrying about silent failures.

This is not uptime monitoring
Uptime monitors ping your server to see if it responds. Inactivity monitors watch real webhook traffic to see if your integration is actually working. They catch different failures.
| Uptime Monitoring | Inactivity Monitoring | |
|---|---|---|
| What it watches | Whether your server responds to synthetic pings | Whether real webhook traffic is still arriving from your providers |
| Catches | Server crashes, DNS failures, network outages | Broken handlers, provider-side failures, silent config changes, expired API keys |
| Blind spot | Your server is up but your Stripe handler has been silently broken for a week | None — if webhooks stop, you know |
| Alert trigger | Endpoint returns non-2xx or times out | No webhook received within your configured threshold |
| False positives | High — transient network blips, maintenance windows | Low — if your provider is sending and your endpoint is healthy, traffic flows |
How inactivity monitors work
Monitors watch for silence, not errors. If expected webhooks stop arriving within your configured threshold, you get an alert.
Attach a monitor to an endpoint
Pick any Debug Endpoint and set an inactivity threshold — the window of silence that triggers an alert. Thresholds range from 1 minute to 24 hours.
Choose notification channels
Get alerted via Email, Slack, or both. Alerts go to the people who can actually fix the problem — not a noisy shared channel.
Set a cooldown period
Prevent alert spam. After an alert fires, the cooldown suppresses duplicate notifications for a configurable period so your team isn't buried in noise.
Track recovery automatically
When webhooks start arriving again, Hooklistener logs the recovery event. You get a full timeline: when it went silent, when the alert fired, and when it recovered.

Comparison FAQs
Why not just use PagerDuty or Datadog?
Those tools monitor your infrastructure — servers, containers, error rates. Hooklistener monitors your webhook integrations specifically. It knows when Stripe stopped sending, not just when your CPU spiked.
Can I monitor webhooks from any provider?
Yes. Any webhook that hits your Hooklistener endpoint is monitored. Stripe, GitHub, Shopify, Twilio, or your own internal services.
Is this included in the free plan?
Monitors are available on Pro ($12/mo) and Team ($20/mo) plans. The free plan includes a Debug Endpoint with request history to get started.
