outline-server
Outline Server, developed by Jigsaw. The Outline Server is a proxy server that runs a Shadowsocks instance and provides a REST API for access key management.
Yes, fly.io allows you to expose a UDP port. See the [fly.toml](https://github.com/patte/fly-tailscale-exit/blob/main/fly.to...) in the repo. To make, the tailscale port [is pinned](https://github.com/patte/fly-tailscale-exit/blob/main/start....) to the exposed port (41641 in that case).
I just tested it again and the connections are made directly (after the first 2,3 go via DERP):
Isn't the problem that the exit IPs will be flagged / blocked, meaning at best you'll get a ton of captchas etc.? I have set up personal Wireguard VPNs with Algo[1] before on DO, and while they work fine, they cause a lot of friction for that reason.

I've recently built something similar [0], but the complete opposite. I wanted to forward traffic onto my homeserver without a public IPv4. I've tried Tailscale Funnel, but the inability to use custom domains made me look for other solutions. I ended up with a fly.io app acting as a TCP proxy over Tailscale. Considering how crappy the setup is, it's surprisingly reliable. Great job fly.io and Tailscale teams! I haven't had any issues in the month or so I've been using it.

I added updates at https://github.com/spotsnel/tailscale-tailwings to make this more 'practical'.
If you just want to run a simple wireguard vpn from fly.io, without tailscale, I wrote a script to spin one up[0]

Outline[1] is significantly easier to use. They have out of the box support for AWS, GCP and Digital Ocean. You can have your own VPN setup on digital ocean for $5 a month, and you can generate keys and share the VPN with friends/family who then only need to download the Outline app on their device. I have zero affiliation with outline but it's an incredibly useful tool, I was looking to build something similar when I discovered it.

Tailscale makes outbound connections so it circumvents the need for IPv6 with things like CGNAT.
OP, why not use an open source equivalent to Tailscale Funnel? For example, I work on the OpenZiti project and we created zrok.io which is fully open source alternative - https://github.com/openziti/zrok.
It's private in that it's your own VM you're running the VPN on. No one else has access to it. Whether you trust Google or not, it's all open source[1].

I've been running wireguard on my own for a few years. I like it, but wish there was a better GUI.
I tried installing headscale. I didn't feel like I got the immediate rush of "cool, I have the baseline thing working" without reading the docs. And, I needed to use this for a GUI: https://github.com/gurucomputing/headscale-ui. I love the command line and am happy to use that, but I'm unsure if there is a benefit to headscale over wireguard if I'm doing that.
I just read this article on tailscale vs. openziti and it mentioned netmaker (a YC company). I tried installing it, but out of the box, "DNS" did not seem to work correctly.
Is anyone here a power user that also benefits from a full fledged GUI? Is tailscale the only option there? I prefer to self-host whenever I can, despite loving tailscale and the people behind it.
