Is there something like this (or trello), that you can self-host on a site? I appreciate that these sites provide free accounts etc, but I am in an association and we have our own simple site already with no advertising or tracking. It would be nice to be able to collaborate internally. I did set up a wiki on another site a few years ago, but I recall it being a bit of faff to set up (wikis being generally aimed at being open, not private)
I understand what you're saying. One of the top requests from our users is actually a self-hosted version of our service. While we are exploring this possibility, nothing is guaranteed for now.
It was a side project of mine along with working two jobs and studying at university - progress was definitely very slow. But since January, I have created a team of three and focused on this project to flesh it out into a startup!
I will also make it more clear that we don't support mobile yet. However, I hope you enjoyed what we're offering right now!
We have swapped out trello with Ryeboard for our team's internal use. We will probably swap out our current road-map trello board for a Ryeboard one later this month!
