Hook0 is a real-time API and App dashboard for managing webhooks.

• Free & open-source. No artificial limitations, vendor lock-in, or hidden paywalls.
• REST API. JSON REST API and integrations makes it easy to trigger webhook events from your Application and connect to every available SaaS
• Fine-grained subscriptions. Enable your users to subscribe to your events by setting up a webhook. They can choose which event types they want to receive.
• Auto-Retry. If Hook0 can't reach a webhook, or if it does not respond with a success code, Hook0 will try again automatically.
• Event scoping. Scope events to one or several levels of your application.
• Events & responses persistence. Hook0 keep tracks of every event your application sent it and of every webhook call. Best for debugging !
• On-Prem or Cloud. Run locally, install on-premises, or use our self-service Cloud service (free tier available).
• A modern dashboard. Our dashboard app is safe and intuitive for non-technical users, no training required.
• Project fully sustainable since day 1. Fork it, twist it and help us build the best open source webhook server for applications
