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. Hook0 supports secure webhook delivery with HMAC signatures, key rotation, TLS encryption, and compliance-focused deployment options. As a fully open source platform, it allows teams to audit the codebase and self-host on their own infrastructure.

WebhookX
WebhookX is an open source webhook gateway for receiving, validating, transforming, and delivering events at scale. It is designed to sit between event sources, internal services, and downstream consumers, giving teams a centralized layer for webhook traffic instead of scattering verification, routing, retries, and delivery logic across many applications. It helps developers handle inbound and outbound webhook flows through one gateway, making it easier to process events securely, route them to the correct services, transform payloads, and keep delivery behavior consistent as systems grow. WebhookX focuses on the parts of webhook infrastructure that are often difficult to maintain in-house, including event validation, request handling, event transformation, delivery management, and scalable processing. Its architecture is built for teams that need webhook workflows to remain reliable under production traffic.
