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.

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.

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

I like freescout.

It is well made and aesthetically pleasing but it has four main problems

1. The devs are complete assholes. Ask for a clarification because of missing documentation and they ban you from their GitHub repo without even replying.
2. The program is open source but everything is under closed source paid plugins. Plugin pricing is very cheap and without subscription but in order to get the bare usable minimum you need to spend at least $50 in plugins. I had to compile an excel file with the list of 50+ plugins and rank them, so I could buy the $400 of plugins over an year, buying the most important in the beginning. Then they banned me because after the first purchases I asked help with one of their paid plugins. Well, thanks for let me save $390, I won’t buy anything anymore.
3. Plugins have unfair regional pricing for some reason. $2 becomes €4, even with vat the math doesn’t add up. They take the amount in dollars, convert in local currency using unfavorable exchange rate and rounding up, then they add VAT and round up again. With 40 “must have” plugins, this trick becomes expensive for no reason. Why Europeans have to pay double? It’s a business expense in 90% of cases, so the vat shouldn’t be considered in the price because a business can deduct them.
4. No support. At all. Even if you are willing to pay for it. They don’t want to set a forum, use GitHub discussions or even (ugh, I hate that but better than nothing) discord. For a program that’s used for business this is a bit of a problem. How a company can rely on a software where if something is missing from the documentation and you ask for help, you are simply banned&ignored. You discover than you’re banned when a week later you go to see if someone replied to you. I don’t see why they can’t have a $50/hour support package like anyone else.

As an alternative, there’s uvdesk. It’s similar but when I discovered it I already set freescout with the bare minimum paid plugins like “see all emails”, “see list of customers”, “send later”, “add attachment to the email”.

My partner and I use a git repository on our self-hosted gitea instance for household management.

Issue tracker and kanban boards for task management, wiki for documentation, and some infrastructure components are version controlled in the repo itself. You could almost certainly get away with just the issue tracker.

Home Assistant (also self-hosted) provides the ability to easily and automatically create issues based on schedules and sensor data, like creating a git issue when when weather conditions tomorrow may necessitate checking this afternoon that nothing gets left out in the rain.

Matrix (also self-hosted) lets Gitea and Home Assistant bully us into remembering to do things we might have forgotten. (Send a second notification if the washer finished 15 minutes ago, but the dryer never started)

It’s been fantastic being able to create git issues for honey-dos as well as having the automations for creating issues for recurring tasks. “Hey we need to take X to the vet for Y sometime next week” “Oh yeah, can you go ahead and put in a ticket?” And vice versa.

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

Setup a standard issue tracker. The classic ones like Trac could be a bit limited but the newer, extended systems like OpenProject that try to compete with Jira can do anything. Taiga is also pretty good. OpenProject is very flexible and allows you to go from super simple to super complicated or anywhere in-between. Sprints, no sprints, kanban, whatever you want.

You might also want a wiki. DocuWiki and Wiki.js are !selfhosted favorites.

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.

Going to o throw elog https://elog.psi.ch/elog/ into the mix. I’ve configured it before as a light ticketing system.

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!

Something like Notion or Coda would not fit the bill? You need to do some work to fit your usage (configuring tables/views)

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).

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
