bore
bore is a simple CLI tool for making tunnels to localhost
...Similar to localtunnel and ngrok, except bore is intended to be a highly efficient, unopinionated tool for forwarding TCP traffic that is simple to install and easy to self-host, with no frills attached. (bore totals less than 400 lines of safe, async Rust code and is trivial to set up — just run a single binary for the client and server.) The easiest way to install bore is from prebuilt binaries. These are available on the releases page for macOS, Windows, and Linux. Just unzip the appropriate file for your platform and move the bore executable into a folder on your PATH. You also can build bore from source using Cargo, the Rust package manager.
