flatnotes

There are a few lesser known projects, I used. Trillium - https://triliumnotes.org/ Joplin - https://joplinapp.org I personally use Flatnotes - https://github.com/Dullage/flatnotes with a connected git repository, but this does not meet your requirements.

I've used Flatnotes for about a year or so and if all you want is to write notes in markdown and search them it doesn't get much simpler. It has tags and decent search, but other than that nothing. Easy to sync or backup though with a single folder of text files. https://github.com/Dullage/flatnotes

I use flatnotes[1] on my homeserver with a cronjob, that automatically adds, commits and pushes the whole data directory into a private git repository. It's not perfect, but dead simple and at least I can search, edit everywhere and easily migrate, if I'd find something better. 1: https://github.com/Dullage/flatnotes

I currently use flatnotes[1] as a Frontend with a background cronjob to add, commit and push every night. Works pretty well so far with some acceptable nitpicks. It was a quick and dirty solution to overcome logseq couldn't run in a Server that time... Never needed anything else until now :-) 1: https://github.com/Dullage/flatnotes

I've been experimenting with Flatnotes (https://github.com/Dullage/flatnotes) for a while and really like the design. No notebooks or even folders, just a single directory with markdown files and decent search & tagging. It feels a lot like what happened to email when we gave up all the up-front structuring with deep hierarchies and just said index it and we'll find it when we need to. The project is just "good enough" for what I need, and aside from tiny bugs whenever I find a gap I can either work around it or live without. Constraints are a powerful motivator for both creativity and getting stuff done.
