O was going to make a weak suggestion, but the more I read the stronger my suggestion becomes. I strongly recommend you look at Silverbullet. It’s similar to Obsidian in that everything is a markdown file, but has an excellent query language. For example in a random file I add a task with a tag, e.g.

* [ ] Do something [priority: 30]

Then on my homepage I have this block of code:

\```query
task where done = false and
priority > 0
order by priority desc
render [[Library/Core/Query/Task]]
\```

Which renders as a list of all my tasks on all my files ordered by priority, you can see how this becomes extremely customizable, e.g. using where page = Some/Page will only render tasks from that page.

It’s not a kanban board like you asked, but it’s great for all those stuff, and it’s highly customizable to whatever you need.

You can keep track of problems each on their own page and have a frontmatter with general information that can be queried as if it were a database.

For example I keep one page for each tool I use at my work, and on the index of my work I have a table that shows these tools and links or cli examples.

Since you are considering kanboard and wekan, take Focalboard https://www.focalboard.com/ in consideration as well.

I use logseq (similar to Obsidian) with a To-Do plugin. Logseq has a journal feature, so I can write all tasks that come up in a day, and then I can view all tasks across all days using the to-do plugin.

Then you can use some sync tool (syncthing for example) to sync all your notes between desktop & android. That way, you can create tasks on both your phone & desktop.

I use youtrack. It’s a project management tool. It’s not open source, but does have a self hostable option.

Click up! I think it’s an excellent UI/UX. Highly customizable. I used it for like 2 years to great effect.

Don’t be too off-put by the “get started, it’s free.”

It’s totally free if you’re using it for 1 project (yourself). If your a business with a dozen clients or something, you’ll edge into the territory of needing to pay. At least it used to be!

org-mode.org ?

After finding out that tools that are to “bureaucratic” don’t stick with me (bureaucratic as in, I need to fill out forms to create projects/tasks, update them and follow defined workflows), I ended up with Trilium.

It at first looks like a very free-form note taking app (a tree of documents on the left, click and edit away), but it has a lot of extra functionality that lets you construct journals and tasks lists in the document tree (like its Task Manager which is already set up in the Demo notes of a new Trilium install).

appflowy is foss, self-hostable via docker, and supports notes, tables, etc. but also kanban boards which i find useful for self management.

I’m using notion atm (the software appflowy has cloned to bring it to FOSS) as I’ve not set up docker yet :'(

I don’t have any recommendations to make here, I just wanted to chime in and say I am looking for the same tool and I’m glad someone could put into words what I wanted.

I might miss your target, but have you considered tasks.org android app + caldav?

I have been using silverbullet the last few months, but I struggle keeping up with its updates (too bleeding edge at the moment). I has a lot of nice features like all markdown, queries and templates.

Now I am back to tasks.org app + radicale self-hosted caldav server. For tasks it flows so well on android. for windows you need to use something that supports caldav, like thunderbird.

When silverbullet matures and if it is still fast and offline, I might go back. It has a lot of nice stuff going on. I still use for stuff like recipes and travel lists

It might be a bit overboard, but I have a Redmine instance running on my NAS that can likely do everything you want. Some out if the box, some with plugins. It’s pretty nice. If you don’t want to worry about installing it you can download a complete installer from Bitnami.
