You have a backlog full of features your users actually want. Retries, signatures, monitoring, dead letter queues: that is 3+ sprints of plumbing. With Hook0, it is 30 minutes.
Sending an HTTP POST is easy. Building a production-grade webhook system is not.
Exponential backoff, jitter, max attempts, circuit breakers. You will ship bugs here. Everyone does.
What happens when retries are exhausted? You need DLQ storage, alerting, and manual replay tooling.
Cryptographic signing, key rotation, timestamp validation, replay attack prevention. Get any of this wrong and your customers' data leaks.
Dashboards, delivery logs, success/failure rates, latency tracking. Your first customer will ask "did my webhook go through?" on day one.
Endpoint registration, event type filtering, URL validation, multi-subscription support. This alone is a month of work if you do it right.
Database migrations, scaling, on-call rotations, security patches. Six months after launch, someone still gets paged for it at 3am.
| Aspect | Build In-House | Hook0 |
|---|---|---|
| Time to production | 3+ sprints (6-12 weeks) | 30 minutes |
| Engineering cost | 2-3 FTE for months | One developer, one afternoon |
| Ongoing maintenance | Continuous (bugs, scaling, patches) | Managed by Hook0 |
| Retry logic | Build from scratch | Built-in exponential backoff |
| Security (HMAC) | Implement and maintain | Automatic on every event |
| Monitoring & logs | Build dashboards | Included out of the box |
| Subscriber portal | Build a whole UI | Embeddable portal included |
| Vendor lock-in | None (but locked to your code) | None (open-source, self-hostable) |
One API call. One. Hook0 does the rest.
curl -X POST https://app.hook0.com/api/v1/event \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"event_type": "invoice.paid",
"payload": {
"invoice_id": "inv_123",
"amount": 9900,
"currency": "eur"
}
}'Retries, HMAC signatures, delivery logging, subscriber notification: handled.
Plan for 3+ engineering sprints minimum. Retry logic, dead letter queues, HMAC signatures, delivery monitoring, subscriber management, endpoint health checking. And that is before your first customer finds a bug.
Retry queue maintenance, edge case handling (timeouts, redirects, certificate errors), monitoring dashboards, rate limiting, log storage, subscriber onboarding. None of this stops after v1 ships. It compounds.
Under 30 minutes. One API call to trigger an event. SDKs for Python, Node.js, and others if you prefer.
Yes. REST API and SDKs, so you can run both systems in parallel during migration. No big bang cutover required.
