Smee Client

Smee Client is a JavaScript/TypeScript library that provides a local proxy for webhooks received by the smee.io service, enabling developers to test webhook integrations without deploying their applications to a publicly accessible server. It listens for incoming webhook payloads on a designated smee.io channel and forwards them to a specified local HTTP endpoint. The current stable version is 5.0.0, released in November 2025, which introduced a breaking change making the `start()` method asynchronous. The project maintains an active release cadence, with several minor and patch updates preceding the major version bump, indicating ongoing development and support. A key differentiator for Smee Client is its straightforward integration with the smee.io platform, offering a simple and effective solution for local development and debugging of applications that rely on external webhook events, such as GitHub App development or payment gateway notifications, by tunneling public internet requests directly to a developer's machine.
