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 not manage it (at all) by itself.
Open-sourcing it is an option, but I don't look forward to negative feedback. If anyone else wants Emacs keybindings in Obsidian, I will change my mind :)
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
