localtunnel
A minimal Go implementation to expose localhost servers to the internet via public tunnels.
What is localtunnel?
Localtunnel is a tool that creates secure public tunnels to localhost servers, allowing developers to expose local web applications to the internet for testing or sharing. It solves the problem of needing to deploy applications to test webhooks, collaborate remotely, or demonstrate work-in-progress features. The current version (v3) is a minimal implementation written in Go, serving as both a usable tool and a historical archive of tunneling technology.
Developers who need to test webhooks, share local development servers with teammates or clients, or learn how tunneling systems work through a minimal codebase.
Developers choose Localtunnel for its simplicity and educational value—it's a minimal, open-source alternative to commercial tunneling services that demonstrates the core concepts without complexity. It's also historically significant as one of the pioneering tools in this space.
