Hook0

Open-source webhook gateway with delivery guarantees, retries, and monitoring.

About Hook0

Hook0 is an open-source webhook management platform that lets you send, receive, and monitor webhooks reliably. It automatically retries failed deliveries, logs every event, and provides a dashboard to track webhook health. You can self-host it on your own infrastructure or use the managed cloud version.

It supports multiple authentication methods including HMAC signing and API keys. Webhook endpoints can be configured with custom headers and payload transformations. Hook0 integrates with Zapier, Slack, and any application via its REST API. The core is built with Rust and TypeScript for performance and scalability.

Hook0 is ideal for teams that want a centralized webhook infrastructure without vendor lock-in. It is fully open source under the MIT license, with a cloud tier for those who prefer a managed service. The project is actively maintained and has a growing community of contributors.
