And yet the saying goes 'Ideas are cheap, execution is everything.'

Why? It is a very practical choice.

Rust for the backend, React for the frontend, what's the problem?

Thanks for mentioning.

Locally hosted server? AWS ECS instance?

I also realize there's Amazon CodeCommit, interesting.

How does it handle conflicts?

Tailscale is one of those services that feel too good to be true. I have known about it but can't get myself to trust it.

I agree about too good to be true. I just can't believe it's free for up to 3 users and many machines. But if you look under the hood there is nothing there that you can't build on your own. It's just more hassle to do it. You can install wireguard on every machine that you own and you can manage the keys by yourself, you can add routing tables and internal DNS service. Tailscale just packages that in nice UI with centralized management.

I was thinking about this, but how does syncthing handle conflicts?

Interesting, thanks for bringing it up.

Thank you, I was considering this but I need to be able to not rely on both machines being online.

Yeah of course a firewall, I just don't know enough about the exact setup there, and that's part of my question.

Diving into that rabbit hole now.
