I've used Joplin before which was okay-ish (but borked the e2e encryption during an update).

Now I would recommend Silverbullet if you are really keen on self hosting a notes app.

But the notes that work best for me is simply Obsidian + Syncthing-Fork (you could self host a syncthing server), thanks to its sheer ability to adapt to nearly any use case thanks to its plugin.

After trying a bunch, I'm using Obsidian + now. Good thing with Obsidian is your notes are ultimately a bunch of plaintext files, so you can do whatever you want with them, and it comes with clients for most platforms.

Another option is Trilium, it is pretty powerful, and has a webapp so as long as you can access a browser, you'll be able to access your notes. https://github.com/zadam/trilium

I use Memos and love it.

I connect to it from my desktop at home and from my phone via a WireGuard VPN and it's everything I need. Worth a look, I think.

Welcome to the rabbit hole of selfhosted note-taking apps. https://selfh.st/apps/?tag=Note-Taking

Unfortunately, this is going to be a bit of a journey. You'll probably end up going through a few of these options until you find one that works for you and fits your workflow.

Trilium. You'll be ~~glass~~ glad you tried it.

Went with Joplin and using it since.

I setup nextcloud and just use that to backup my Obsidian notes. But I also use next cloud deck depending on the type of notes or list I'm making

I'd vote for anytype or obsidian

Anytype has a learning curve, But it has built-in encryption and IPFS syncing provided by the company. The templating system is really slick and the relational aspect is pretty solid.

Obsidian + syncthing fork is a really solid contender. It's much easier to work with out of the box but the features are a little more generic.

Neither of these are really self-hosted, so much as they are contained in their own ecosystem. You get some measure of higher availability that you have to really work for if you're really self-hosting a product.

Obsidian is pretty neat. Can use it with Syncthing, although I guess you need Syncthing-Fork on Android now.

I use nextcloud notes because I already have nextcloud and my needs are not that sophisticated

Nextcloud is a really good all-in-one solution for self hosting data

I use Joplin, no complaints.

I've been getting on well with notesnook, the self hosting is in beta right now but its just a docker container. Docs are coming for self hosting in the near future.

My solution is basically what @mojolobo mentions with Nextcloud behind it and I love the concept. Because Obsidian (via a WebDAV plugin on the phone) just syncs with the "Notes" folder in my Nextcloud root it really is just a bunch of .md (markdown) files. It gives me an added sense of security (on top of the self-hosting aspect) because I can see those files everywhere I have Nextcloud installed, I can edit them manually if I wanted to. On the PC you just point the Obsidian app to the folder, on phones you do it via a WebDAV plugin.

It's still in alpha but hoarder is promising

It's designed to organize bookmarks, but can also support markdown notes with picture (a single picture, not multiple pictures)

Unfortunately at the moment the mobile app is so alpha that doesn't support creation or editing such notes, only new bookmarks or new photos.

It uses a headless chromium to make screenshots for URLs.

Optionally, can use a bullshit generator like ollama or openai api keys to automatically create a lot of useless tags to each note

I use https://silverbullet.md and love it, it's a bit more than a note taking app, but it's definitely worth it.

Probably Joplin is the easiest to use. Looks like OneNote but it's different in many ways.

Appflowy if Notion appels you. It is not 1.0 yet so some features you need might not be there.

I use Joplin on top of Nextcloud.

I'm just using a self hosted git repo with markdown files. I was having trouble finding something open source that I could edit with vim that also had a good mobile solution. I also didn't want to get locked into a file format that was specific to an app.

Markdown is ubiquitous and I use git all the time as a developer so it was easier to tack something onto an existing workflow. It's a little janky but at least I won't be screwed by devs abandoning whatever app I was using.

Logseq + SyncThing-Fork for me. The killer feature I was looking for to switch from Evernote was voice recording support, logseq is the first thing I've found that does a decent job of it while having a solid Workflowy-style "bullets all the way down" interface, which I've come to appreciate. The mobile app still leaves a lot to be desired, it's a little clunky with lots of buttons and very limited swipe gestures. Gets the job done anyhow, and the desktop app is amazing.

I use radicals for CalDAV and save notes there together with my calendars. On Android there is jtx Board which let's you work with them. Sadly on Linux I couldn't find anything so I started writing something myself but don't have much time to work on it https://github.com/jeena/JNotes
