This seems like an interesting approach to organize data. Are there any open source implementation that I can customize myself and host on my own personal server?

Some assembly required, but:

I have a self-hosted solution. It's in an alpha state, not ready for public consumption, but would love any feedback from people willing to try it out. Here it is:

https://github.com/ryanfmurphy/db_viewer

This started as a DB Admin tool ala PhpMyAdmin, but I now use it for Todo lists, tree-style mind-mapping / brainstorming, tracking finances, etc.

If you give this a shot feel free to email me for help setting it up / getting the most out of it. (Email is in my profile)

i found https://rockiger.com/en/akiee/, but not web based and seems to be dead.

I'm also interested in self hosted apps.
