Safest CalDAV/CardDAV server [Choice Made] (feddit.org)

After my previous server got hacked (presumably), I am now looking for new solutions to my needs. CalDAV/CardDAV is a big one.

So far I switched from a content management system (PHP) to a static site generator for my blog, and I'm not looking back.

I wonder if it makes sense to also step away from PHP wrt CalDAV/CardDAV.

As ever so often, this list has some nice info.

I'd like to keep dependencies low. Python would be a good choice because it's already installed on my Debian Stable system. But would it be safer?

Back when I started this compatibility with clients was an issue; but I don't use Android anymore. In any case, is this still an issue?

edit: no, I don't use a web based app; and I'd prefer the server doesn't require admin via web UI either.

Thanks for all your replies! I chose Radicale, already set it up. Only what is needed, simple config files. Very nice. It runs under an nginx reverse proxy and they communicate encrypted (and of course the outside is also encrypted and password-protected). And the web UI can be disabled.

The documentation is very tutorial-like and security conscious.

I think Radicale, Baikal, SabreDAV or NextCloud are the most common choices. I read those names a lot.
But I believe only one of those isn't written in PHP.

I'd really recommend digging into the "hacking" though. Unless you learn from your specific mistakes and avoid that in the future, you might run in to the exact same issue again. And I mean it could be a security flaw in the program code of the WebDAV server. But it could as well be a few dozen other reasons why your server wasn't secure... (Missing updates, insecure passwords, missing fail2ban, a webserver or reverse proxy, unrelated other software... There are a lot of moving gears in a webserver and lots of things to consider.)
