# Hook0

An open-source webhook platform delivering, retrying, and signing webhook payloads for developers who send webhooks from their applications.

**Route:** surfaced by the Web Application and Frontend Hosting Platform lane's de-branded queries → competitor to vercel.com.

**Why it's on the map:** Sells the same webhook-delivery capability (deliverability, retries, signatures) to the same developer buyers who would shortlist the anchor's webhook infrastructure.

**Receipts** (verbatim from its page this run):

> Hook0 is an Open-Source Webhooks-as-a-service (WaaS) that makes it easy for developers to send webhooks

> Full delivery, retries, signatures

> HMAC, replay defense, EU-hosted
