Since when can you use regular email? That’s odd. When i checked it out it wasn’t possible and there was even a post why. That tailscale is no identity provider and such things

Any source for the coin stuff? Never read about it

I used nginx proxy manager for a while. Nowadays I use caddy, and I wouldn’t want to look back. It has no gui but a caddyfile. It works much smoother for me.

How does it lock you in? You, the admin, has full control over postgres. Sqlite has no security features. Does it store passwords? Sqlite also locks the database which is usually OK if there are no concurrent jobs. But for such services it sounds like a bad idea to use sqlite. (I am no server/app dev)

Tbo, not using a tool because it only uses postgres sounds strange to me.
