I don't particularly _want_ another login, but I also don't cherish the thought of losing access to Service A because of the actions of Service B.
Luckily not too many, but it still strikes me just how stupid I was to use that option on any site, instead of an email and password.
It's completely self-hosted, so none of your traffic will go through our servers. You can also use basic auth by default (though there is also OAuth). Finally, as a bonus, it's much faster because you can use kernel WireGuard.
I won't claim it's as user-friendly as Tailscale (yet). It definitely requires more technical knowledge to set up, especially considering it's not a SaaS. But if you're willing to get through the initial setup (Day 0 / Day 1), you should be golden.
