What is cloudflared?

This project is a modified version of cloudflared, a tool that lets you expose a local web server or service to the internet safely without opening any holes in your firewall. Normally, if you want someone outside your home or office network to reach a server running inside it, you have to configure your router to let traffic through, which is a security risk. This tool creates a secure, outgoing connection to Cloudflare's network instead, so your internal network stays closed and protected. The way it works is straightforward. You run the tool on the same machine as your web server, and it maintains a persistent connection to Cloudflare. When someone tries to visit your website, Cloudflare receives the request and sends it to your server through that already-open connection. Your server responds back through the same channel. The notable twist in this particular fork is that it adds a persistent "quick tunnel" feature, which lets you test things rapidly without going through the full setup of adding a domain to a Cloudflare account. Someone running a personal project on their laptop who wants to share it with a friend would find this useful. A startup founder testing a prototype from a coffee shop could expose their local app to the internet for a demo without deploying it anywhere. It also works for non-web traffic like SSH or remote desktop connections, so a developer who needs to securely access a home lab machine from the road could use it instead of a traditional VPN. The tool is available as a standalone program for Mac, Windows, and Linux, or as a container image. The project's documentation points to Cloudflare's official guides for most setup steps, and the README notes that only versions released within the past year are supported, so keeping it updated matters.
