The purpose of this list is to track and compare tunneling solutions. This is
primarily targeting toward developers and self-hosters who want to do things
like exposing a local webserver via a public address.
# The dream
I started this list because I'm looking for a simple tool/service that does the
following:
* Allows me to register a domain name and automatically points the records at
the server running the tunnels.
* Automatically sets up and manages HTTPS certificates (apex and subdomains)
for the domain.
* Provides a client tool that tunnels TCP connects through the server without
requiring root on the client.
* Provides a simple interface to allow me to map X domain/subdomain to Y port
on Z client, and proxy all connections to that domain.
So far I haven't found a tool that does all of this. In particular, while some
of them can do automatic certs through Lets's Encrypt, none of them integrate
the domain registration and DNS management.

# Commercial/Closed source
* [ngrok 2.0](https://ngrok.com/) - Probably the gold standard and most popular. Closed source. Lots of features, including TLS and TCP tunnels. Doesn't require root to run client.
* [Tailscale](https://www.tailscale.com/) - [![tailscale github stars badge](https://img.shields.io/github/stars/tailscale/tailscale?style=flat)](https://github.com/tailscale/tailscale/stargazers) Built on WireGuard. Easy to use. Doesn't include an HTTPS proxy on the public side, but could be combined with nginx/Caddy/etc. Some [code](https://github.com/tailscale) available, but I'm not sure what the implications of the custom license is.
* [CloudFlare Argo Tunnel](https://www.cloudflare.com/products/argo-tunnel/) - $5/mo + $0.1/GB. Integrates with Argo smart routing. Client source code is [available](https://github.com/cloudflare/cloudflared).
* [localhost.run](https://localhost.run/) - Simple hosted SSH option. Supports custom domains for a cost.
* [Packetriot](https://packetriot.com) - Comprehensive alternative to ngrok. HTTP Inspector, Let's Encrypt integration, doesn't require root and Linux repos for apt, yum and dnf. Enterprise licenses and self-hosted option.
* [serveo](https://serveo.net) - Mentioned quite a bit the last couple years, but appears to be down currently. Simply uses SSH for tunneling.
