I'm on the free plan, all the basic options to run a project are there and the mail notification/comment system works very well. The user interface is good. My only complaint is that you cannot have more than one person assigned to a task. It's their philosophy and they say that if you want to have more assignees you should either duplicate the task or create subtask (only for paid plans).

Leantime (https://leantime.io) does everything you just mentioned and gives you a little more room to grow if you need it. The claim is to be for the “non-project manager” so good for non-technical teams or teams looking for something to get in and get out of. Source: about 1 year ago
Deck is very minimal and not really suited for anything beyond simple, personal stuff, in my opinion. As far as self-hosted, my favorite is still Kanboard, which has a lot of plugins and themes to choose from. Leantime is good too and a bit different. I also like Vikunja and Wekan.
