01 / RELIABILITY  ·  webhook infrastructure

Every webhook,
delivered.

Your customer's endpoint just went down at 3 a.m. Hookwise queues the event, retries with exponential backoff, and delivers when it's back — you sleep.

02 / THE PROBLEM

Delivering webhooks reliably is a distributed-systems problem.

Endpoint down = data gone

A customer's server hiccups for 40 seconds and the event vanishes. No queue, no retry, no trace.

DIY retries = two sprints

Backoff, dedupe, dead-letter, a dashboard, alerting. Weeks of plumbing that isn't your product.

"Did you get our webhook?"

Support tickets you can't answer because there's no delivery log to point at.

03 / HOW IT WORKS

One POST in. Guaranteed delivery out.

Send us the event. We own the hard part — the queue, the signature, and every retry.

  1. Receive

    You POST the event to one Hookwise endpoint. Returns 202 in ~40ms.

  2. Queue + Sign

    Event is persisted, deduplicated and signed with an HMAC-SHA256 header.

  3. Deliver / Retry

    We deliver to the destination. On failure: exponential backoff, up to 5 attempts over 6h.

04 / LIVE DEMO

Break things on purpose.

Pick a way for the destination to fail, then send a test event. Watch Hookwise refuse to lose it. Time is compressed ~10× — no backend, it all runs in your browser.

05 / EVERYTHING INCLUDED

The plumbing you'd otherwise build twice.

Automatic retries

Exponential backoff with jitter, up to 5 attempts across a 6-hour window. Dead-letter after.

HMAC signing

Every payload signed SHA-256 with a rotating secret so destinations can verify authenticity.

Replay any event

Re-send a single event or a whole time range from the dashboard or the API. Idempotency-keyed.

Delivery logs

Full request/response history per event — status, latency, attempts. Answer the ticket in one click.

Alerting

Get paged when a destination's failure rate crosses a threshold, before your customer notices.

Transformations

Reshape or filter payloads per destination without redeploying your own service.

06 / DEVELOPER EXPERIENCE

Integrate in one call.

Point your existing event at Hookwise instead of the destination. Keep your payload — we add the delivery guarantees.

  • No SDK required — it's an HTTP call.
  • Idempotency keys prevent double delivery.
  • Same endpoint in every language.
07 / PRICING

Cheaper than building it. Much cheaper than losing events.

Build vs. buy

What does rolling your own actually cost?

Build & run yourself $— ≈120h to build (amortized 12mo) + 6h/mo upkeep
Hookwise $— Free tier

Assumptions are illustrative: build cost amortized over 12 months, blended on-call not included. Your mileage will vary.

08 / FAQ

Questions engineers actually ask.

Is this a real product?

No — Hookwise is a self-initiated concept built as a portfolio case study. The landing page, the delivery simulator and the calculator are fully functional; there is no backend service behind it. Everything runs client-side.

How do retries work?

On a failed delivery we retry with exponential backoff and jitter — roughly 30s, 2m, 10m, 1h, 6h — up to 5 attempts. After the last attempt the event is moved to a dead-letter queue you can replay from.

How do you prevent duplicate deliveries?

Each event carries an idempotency key. If a destination receives an event but its 200 is lost on the way back, the retry is de-duplicated by that key so your customer never processes it twice.

Do I need to install an SDK?

No. Integration is a single HTTP POST to one endpoint — the same in curl, Node, Python or anything that speaks HTTP. See the code sample above.

What happens to events during an outage on your side?

Events are persisted on receipt before we return 202. In a concept like this that's the design intent; a production build would run the queue on durable, replicated storage.
