tunnelmole

It creates a public HTTPS URL that forwards traffic to a locally running HTTP server, allowing developers to expose web servers, Docker containers, APIs, React or Node applications, and static sites without manual network configuration. The tool is positioned as an open‑source alternative to similar tunneling services, offering a free HTTPS endpoint when using the default settings.

Typical users include developers who need to test webhooks, automate workflows with services like IFTTT, debug mobile or cross‑device experiences, and share work in progress with collaborators. By providing a reachable address, it enables real‑device testing of features such as Web Notifications and progressive web apps.

Installation can be performed via npm for Node 16.10+ or by downloading pre‑built binaries for Linux, macOS, and Windows. After installing, the command line utility is invoked with the local port number to start the tunnel, producing the public URL for immediate use.
