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.
