Reaching home apps from outside

I want to pick an open-source replacement for ngrok, Cloudflare Tunnel, Tailscale Funnel (getting to home-server apps without opening router ports). Below is a list from Open Source Everything (CC BY-SA 4.0), in the order its website shows it. The order is a starting point, not a verdict. - frp: frp is a free tool that lets a computer behind a home or office network be reached from the internet, without opening ports on the router. It is aimed at people and IT staff who need to reach a private server or app from outside, and it requires running a small program on a public server. [Advanced setup; Windows · Mac · Linux · Android; replaces fully; Apache-2.0; https://github.com/fatedier/frp] - Pangolin: Pangolin is a program that lets you reach computers, websites and private services on your home or office network from outside, and control who can get in. It is aimed at system administrators and people who want to self-host their own secure access instead of using a closed cloud service. [Advanced setup; Linux; replaces fully; AGPL-3.0-only; https://github.com/fosrl/pangolin] - zrok: zrok is a tool that lets people share a web service, folder, or network resource from their own computer with others over the internet, without changing router or firewall settings. It is aimed at people who want a quick, secure way to make something they run at home reachable by others, and at developers who want to build that sharing into their own programs. [Advanced setup; Windows · Mac · Linux; replaces fully; Apache-2.0; https://github.com/openziti/zrok] - bore: bore is a small free tool that makes a program running on your own computer reachable from the internet, by forwarding its network port through a server. It is aimed at developers and people who want a simple, self-hosted alternative to services like ngrok. [Advanced setup; Windows · Mac · Linux; replaces partly; MIT; https://github.com/ekzhang/bore] - rathole: rathole is a command-line program that makes services on a device behind a home internet connection reachable from the internet, by routing traffic through a server that has a public address. It is aimed at people who run their own servers and are comfortable editing configuration files. [Advanced setup; Windows · Mac · Linux; replaces partly; Apache-2.0; https://github.com/rathole-org/rathole] Setup rating: "Easy setup" means you can install it like a normal app, use it in a browser. "Advanced setup" means you must run it on your own server or use the command line, or it is a tool for developers. Full details: https://opensourceeverything.org/data/groups/tunnels.json Before recommending anything, ask me these three questions (one at a time, in plain words): 1) Which device or devices will I use it on (Windows, Mac, Linux, Android, iPhone)? 2) How comfortable am I with technical setup: only installing apps from a store, happy to follow a step-by-step guide, or comfortable with servers and the command line? 3) What is my budget: free only, or willing to pay for hosting or support? Then recommend one to three projects from this list only, and for each say why, using how fully it replaces the app, its setup rating, and the devices it runs on. If nothing on the list fits me, say so plainly instead of stretching.

Read the list of open-source projects at https://opensourceeverything.org/data/groups/tunnels.json. Compare it with my project or idea below. Tell me which projects overlap, what I could reuse instead of rewriting, and what mine does that none of them do. My project or idea:
