WebHook Tester

Overview

WebHook Tester is an open-source, self-hosted utility designed for developers to easily inspect and debug incoming HTTP requests. It functions by generating a unique, temporary URL that acts as an endpoint. When any service or application sends an HTTP request to this URL, WebHook Tester captures the request and displays its full details—including headers, body, query parameters, and method—in a clean, real-time user interface.

This tool is particularly valuable for testing webhook integrations from various platforms like payment gateways, version control systems, or communication tools. By providing a private and controlled environment, it allows developers to verify the exact payload and structure of requests without relying on public, potentially less secure, alternatives. Its Docker-based deployment makes it straightforward to set up and run on any server, offering flexibility and independence for development and testing workflows.
