Tunnelmole

Tunnelmole is a command-line tool that gives locally running HTTP and HTTPS servers a public URL. It is designed for developers who need to expose a local app, API, Docker container, Node project, React app, or static site for testing and sharing. By running a simple command with a local port, users can route public traffic to a service running on their own machine. The project is often compared to ngrok, but it is open source and can be used with the public hosted service or a self-hosted Tunnelmole service. It is especially useful for testing webhooks, sharing work-in-progress apps, mobile testing, client previews, and development demos. Its main value is making local development reachable from the internet without manual router configuration or deployment.
