FastHook
FastHook is a webhook infrastructure and event delivery platform built for developers and product teams that need a reliable way to receive, inspect, transform, route, and deliver webhook traffic. It acts as a programmable layer between incoming event sources and downstream destinations, making it easier to debug integrations, monitor event flow, and control how webhook data moves through a system.
The product lets teams create sources, destinations, and connections so they can ingest webhook requests, inspect payloads and metadata, apply routing or transformation logic, and forward events to the right services. It includes tooling for viewing requests and events, managing retries, tracking delivery outcomes, and understanding failures when integrations break. FastHook is designed to reduce the operational pain of webhook-based systems by giving teams better observability, replayability, and control over event processing.
It can be used for a variety of integration and automation

Hook0
Hook0 is an open source Webhooks-as-a-Service platform that helps developers send, receive, manage, and monitor webhooks at scale. It is built for teams that need to add webhook support to their product without spending weeks building retry logic, signatures, monitoring, queues, dead letter handling, event logs, and subscriber management from scratch. With one API call, teams can publish outbound events, while Hook0 handles delivery infrastructure, configurable retry logic, webhook calls, endpoint monitoring, event persistence, and developer tooling. It keeps track of every event an application sends and every webhook call it makes, helping teams debug integrations, inspect delivery attempts, and maintain an audit log.
