Overview

Hook0 is a webhooks-as-a-service platform: your application POSTs an event to its REST API and Hook0 handles routing to subscribers, retries, payload signing and TLS. Subscribers can register several endpoint URLs, pick event types and filter by labels. Every attempt is logged so deliveries can be inspected and replayed.

Best for: SaaS teams that need to send webhooks to their customers without building the delivery layer
Pricing: Free Developer tier, then €59/month (Startup) and €190/month (Pro, or €1,824/year), with custom Enterprise pricing and per-event overage above the daily quota.
Runs on: WebSelf-hosted
