About

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.

About

Webhook.site is a tool for testing, transforming, and automating web requests, webhooks, and emails through unique URLs and email addresses that show everything sent to them instantly. With Webhook.site, users receive a unique, random URL that can be used to test and debug webhooks and HTTP requests, inspect payloads, headers, query strings, and request details in real time, and replay items later when troubleshooting or reprocessing failed flows. It helps remove the frustration of building software and automations that communicate through webhook or email by making requests visible, persistent, and easier to understand. Webhook.site also supports Custom Actions, a graphical workflow editor that runs when a URL receives a request or email, allowing users to connect incompatible APIs, convert an HTTP request to an email or vice versa, transform, validate, and process requests, and build workflows that would otherwise require development work.
