Loud alerts.
The moment they
happen.
Point any service that can send an HTTP request at a URL Webhook Notifier gives you. When it fires, your phone rings. The alerts you mark urgent ring through Silent, Focus, and Do Not Disturb using Apple Critical Alerts on iOS and DND-bypass channels on Android.
Free on iOS and Android. Apple Critical Alerts opt-in, per webhook.
Features
Built like a piece of operations gear.
Six things that matter when an alert at 3am is the difference between a fix and an incident report.
Per-webhook match rules
HTTP method allow-list, header equality, substring or regex on the body. Quiet noise out at the door.
Quiet hours per webhook
Days of the week and a time window per webhook. Outside the window the alert is dropped silently.
Critical Alerts
On iOS we use Apple Critical Alerts, the same capability medical and safety apps use. On Android we use a high-importance channel with DND bypass. Either way the alerts you flag as urgent ring through Silent, Focus, and Do Not Disturb. Opt-in per webhook so you choose which alerts get the privilege.
Read-only sharing
Hand a teammate the secret. They subscribe and get every alert. Rotate the secret to revoke.
Audit log
Every request that hits your URL is recorded. Method, body excerpt, time, and whether your rules matched.
No tracking, no analytics
No advertising IDs. No analytics SDKs on what your webhooks contain. Bearer tokens are stored hashed.
How it works
Four steps. No accounts. No middleware.
A typical setup takes about two minutes. Once it's wired, you stop checking dashboards and start trusting your phone.
Your service
A monitor, CI server, smart home hub, or a script you wrote.
›Hits a URL
The unique webhook URL we mint for you.
›Your rules pass
Method, header, body match. Outside the time window? Dropped.
›Your phone rings
Loud, audible, even through Silent and Focus when you say so.
In the app
Three screens. That's the whole job.
List your webhooks. Tap one to see the events and tweak rules. Get woken when the rules pass. That is it.
Common questions
Frequently asked.
What is Webhook Notifier?
A push-notification utility for iOS and Android. You mint a unique HTTPS URL inside the app, point any service that can issue an HTTP request at that URL, and your phone rings the moment it is hit.
Does it support Apple Critical Alerts?
Yes. The app uses Apple Critical Alerts on iOS for the webhooks you opt in to, so urgent alerts ring through Silent, Focus, and Do Not Disturb. On Android we use a high-importance notification channel with DND bypass for the same effect. The bypass behaviour is opt-in per webhook.
How much does it cost?
Free.
What can I use it for?
Production monitoring alarms, CI failure notifications, on-call paging from another tool, self-hosted security alerts, smart-home events like water leak or smoke alarms, or any custom script that needs to wake an operator.
Can I share a webhook with a teammate?
Yes. Share the secret. Holders of the secret subscribe and receive every alert in read-only mode. Only the creator can edit the webhook, rotate the secret, or remove subscribers. Rotating the secret revokes every other device.
How are matches decided?
Per webhook you set an HTTP method allow-list, an optional exact-match header rule (key plus value), and an optional body rule (substring or PCRE regex). All rules must pass for an alert to fire.
What about quiet hours?
Each webhook has a day-of-week mask and a time-of-day window. Requests that arrive outside the window are logged but produce no notification.
Do you sell my data?
No. There is no advertising, no analytics SDK on the contents of your webhooks, and no third-party tracking. The bearer token that authenticates your device is stored as an Argon2id hash. Apple APNs and Google FCM see only the encrypted-in-transit alert payload, never the rest.
