About
Hook0 is an open-source webhooks-as-a-service platform that lets developers send webhook events through a REST API. It handles delivery attempts, retries, HMAC signatures, TLS encryption, replay defense, monitoring, and replay from a dashboard or API.
The hosted cloud plan includes a free Developer tier with 1 developer, 1 application, 10 event types, 10 subscriptions, up to 100 events per day, 7 days of data retention, and no credit card required. Hook0 also offers self-hosted and dedicated on-premise options for teams that need infrastructure control or data sovereignty.
- 100 events per day free
- 1 developer and 1 application
- 10 event types and subscriptions
- 7 days data retention
- HMAC signatures and TLS encryption
- EU-hosted cloud data
- Self-hosted open-source option
Free Tier Value
This free tier is a capped but genuinely usable starter plan: it includes a managed service, one developer, one application, and up to 100 events per day, but extra events are blocked and retention is limited to 7 days. The cheapest paid cloud plan is Startup at €59/month (about $59), so the free tier is worth roughly that amount for a small project, though with much tighter limits and no credit card required.
