This made me realize that obsidian is *not* opensource, but in a way obsidian made me feel like it was opensource. Obviously now that I researched it, it is quite obvious that it is not, but still it 'feels' like it should be opensource.

I had absolutely no idea either, I had just assumed that it was, which was a dumb assumption to make. Thanks for pointing it out!

another one in the same space: https://helixnotes.com/

Is this related to https://helix-editor.com/ ??

AFAICT no. It's similar to Hermes Agent and the Hermes JavaScript engine. They are two very different things. Though you could argue that both Helix projects are editors but I don't think that's meaningful in this instance.

AI'm building a native version[0] of Obsidian in Qt6 (QWidgets, cpp), replicating the markdown editor takes a while, there are so many ways of corrupting the file or losing the rendered markdown style... but its getting there[1] and its lightweight, using about 15mb ram, no gpu and barely uses any cpu when the cursor or scroll moves, like a text editor should be. Still need to render widget tables, lists and syntax h…

I open sourced https://asnotes.io - it's markdown based with wikilinking, task management, a kanban board and static site publishing. It runs locally and is Git friendly. The aim was to build something using formats and tech that is likely to stand the test of time.

Interesting. I recently "vibe-coded" my personal Obsidian clone, because I want proper Emacs keybindings, and Obsidian does not support those, not even through extensions. I do not know what to do with my pet project. I'm using it myself, and it has tons of futures that took quite some effort to get right. For example, WYSIWYG table editing is not trivial, and Claude Opus agrees with me, in the sense that it could no…

I too have vibe-coded my own personal obsidian/sublime replacement in rust, and also ran into WYSIWYG table editing and rendering issues with opus 4.7. Took a couple iterations but now formulas/rendering are perfect. GPT5.5 actually handled that very well compared to 4.7

Big fan of the note up front about how long they’ve been working on it, feel like we’ll be seeing a lot more of that as an anti-slop signal

Thanks. Even though there's "LICENSE.md 3 years ago" file, today I also added this text :)

This is hand crafted, for the most part.

I really like the look and feel!

It appeals to me as a minimalistic version of the Bear[1] notes app.

A few years ago I played around with copying the Bear app interface for the web, the idea was to create a visually identical mockup of the app so you could immediately visualise changes made when customising various theme values. I stalled with the implementation of the last part, but the rest of it is up at bear.christippett.dev

Wait, why are you mixing the two? You can have the software be under an open source license, yet still not be a monk that has taken a vow of poverty, it's not black and white. AFAIK (as a long-term Obsidian daily user) Obsidian makes their money on various things attached to the editor/viewer itself, but don't actually charge for the editor/viewer. Even if they did, they could still slap a FOSS license on it, and con…

"Wait, why are you mixing the two? You can have the software be under an open source license, yet still not be a monk that has taken a vow of poverty, it's not black and white." I don't think they are mixing the two. If they open sourced it, there would be immediate competition. Anyone could fork it and circumvent/compete with any premium features they might want to add to it in the future. It's very hard to use this…

Well they'd just release it under a non-commercial license. The majority of their income comes from Obsidian Sync, and someone can't just host their own version of Obsidian Sync for all the Obsidian users for free. And there are already self-hosted alternatives to Obsidian Sync, in fact Obsidian even endorses them themselves[1].

As for their other paid service, Obsidian Publish, since all Obsidian notes are in plain markdown there are already many free alternatives.

So open sourcing would not harm any of those income streams. It's not about Obsidian losing profit. If you want to read the actual reasons they have decided not to open source Obsidian, they have talked about it on their forums[2]

> So that anyone could tweak it however he wants. That was true before the "AI era" as well.

Well, yes. Just now, any regular user can clone the repository and ask an LLM to tune it to his needs.

I never thought about this before, and it hasn’t been mentioned significantly in the vast amount of AI threads I read here. But it’s a really good point as skeptical as I am (in mid-2026) of AI first codebases

Why should it be opensource? Obsidian gives you complete control of your data, which it stores in an open standard. Please explain to me why developers should act like monks who've taken a vow of poverty? The devs built something valuable, they should profit from it.
