Selfhosted

I used logseq for my first semester of university and I can't see any reason to switch right now.

It handles markdown and KaTeX, so it handles everything I need really, in a fast simple program.

Perhaps not as full featured as the others, but I host wiki.js for my knowledge base on my local server.

I've been using Trilium Notes for the better part of two years and love it. I have used Obsidian and similar markdown apps, and I find it frustrating to add images due to the need to store them in a separate folder and reference them instead of just pasting them into the page and being done with it. To me, that's a barrier for notes when I'm trying to brainstorm. I really do like markdown, but it doesn't work with my though process.

I have a sync server setup at home (with no outside access) and do my main writing inside my network. For notes on the go I use the Notes app on my iphone (its quick and easy) and then drop the notes into Trilium when I get home.

Not exactly self-hosted but, I like UpNote a lot.

It's reasonably simple but, powerful enough for me, and it's fast & intuitive

I use https://simplenote.com/ I was thinking about switching to a Foss alternative from fdroid but haven't yet. Works good for me.

This was a good topic to bring up, saw some stuff I have not heard of. Thanks.

I've stuck with Joplin for a while. Self hosting the sync server so it's all saved privately.

Logseq

I use Vscode with markdown preview, with a git repo. The only downside is that Windows incessantly wants to group instances of an application, so it's hard to keep my notes separate from my coding stuff.

Flatnotes for me. I haven’t tried many others, but it was perfect for what I needed. Markdown, writes plain text files so no database/easy to backup

neovim + git with gitea/forgejo

Emacs+org-mode

VSCodium on the desktop, and Markor on Android. I write everything in markdown, and VSCodium is already where I spend half my time editing and writing code, so it was an easy choice. I also use Vim for quick one-offs, especially if I'm already working on a project with it.

Like others here, I also use Syncthing to keep my notes synced between home server, remote clients, and mobile devices.

Hypernotes. Work on every platform.

I personally like Nextcloud notes for quick notes and nextcloud collectives for detailed stuff e.g revision. With nextcloud tables and deck it makes a great notion replacement

Trilium. Tried a bunch but fell in love with this one. Others either didn't have support for inline math or weren't wysiwyg (Joplin). Also easy syncing between computers with its own server in docker, and it even doubles as a web version of the app.

Ghostwriter and syncthing. Ghostwriter really has a good focus mode that really gets me in the right spot for writing. I use Markor if I am on Android and syncthing still works there as well.

Unsaved n++ tabs

vimwiki

combined with some bash aliases, neovim config tweaks, and some bash scripts I've cobbled together over time. Then syncthing to share it across my laptop and desktop.

I've tried a few different note taking apps but I always find myself coming back to vimwiki. Its not the most feature rich 'app'. Matter of fact its pretty simplistic but I dont need or want most of the advanced features of other notetaking systems. But what it lacks in features, it makes up for by being a vim plugin. Seriously, I can't handle using non-neovim text editors/note taking apps. Having all of my neovim plugins, and other config tweaks make vimwiki the handsdown winner over the rest.

The missing vimwiki feature for me was a running "to do list" across all of my notes. So I wrote a script that got me the to-do list feature I needed.

on a desktop or laptop I use Emacs org-mode. on my phone I have tried so many options and the best thing that I found for me is Delta chat. I just use the saved notes which is basically an email to myself.
