My partner and I are using Microsoft To Do to share multiple lists, like a shopping list and ideas for vacations, presents for the kids etc. We already moved from Google to mailbox.org for e-mail and family calendars, but shared tasks somehow can’t be synced to other apps. Do you have any recommendations for good apps where people can share lists, that also have a browser UI (so they can be used on a PC without installation)?


What is it, that is not clear to you exactly? More the whole “run on your own server” thing or just “how vukunja works” on an application level?
(I will try to explain if you want and if I can.)
The hosting, or specifically the joining somebody else’s hosting server, since we currently don’t host our own.
Ah, OK.
So Vikunja itself is “just” an application. And it needs to be executed somewhere. So hosting it on a webserver like your own website would be the “intended way”.
However, web hosting can be a little bit complex, if you have absolutely no prior knowledge about that. So, I wouldn’t recommend it for novices. (But, it can be a fun hobby if you want to learn something new.)
But fortunately, you don’t necessarily need to do the work of hosting it yourself on your own. Other friendly people are already running Vikunja on their server and are providing it as a free service to others. (Check out the two links I provided in my original reply.)
You can sign up on their instance and use it like any other web service. So, I would recommend to open an account at one of their servers for the purpose of trying out Vikunja. If you like it, you can still think about registering somewhere else or hosting it on your own.
Thank you, that really helps.
