Show HN: Opensidian

jpzk

Open-source and non-profit under GPLv3, vault-compatible cross-platform markdown notes app. A drop in replacement that supports most of the functionality. It's based on Rust + Tauri v2. Build it yourself, fork it, or run signed prebuilts RPM, DEB, AppImage and Flatpak.

Long term Opsidian user here. This looks exciting. Especially the UI being so snappy. Do you also support the plugin system?

It’s always good to have alternatives but without plugins this is not really obsidian competitor (yet).

Why do you put a license on it when it‘s obviously not copyrightable?

I love open source. But Obsidian exists. Cloning existing apps to open source is almost push-button in the age of Claude. Obsidian makes a good product and frankly barely charges for it. Yes it's closed source but since all your files are markdown there is no lock-in risk. I guess I'd rather see people in open source make new things than copy existing products especially when those products are made by small scrappy indie companies. If everything gets cloned I don't see who has any incentive to try and innovate the next new thing in commercial markets and honestly I see too little evidence of innovation vs. cloning in the open source world.

UPDATE: added web version for testing https://opensidian.org/webversion/

What’s the benefit of tools like Obsidian vs using whatever code editor you have on hand? Why would I use it over vs, say, vs code?

Not sure why we need a copy to be honest. You also pay for maintenance, updates, integration, etc. It is impressive as a project though.

i'm not much into ethics usually, but this is kinda low. ethics aside, where is the profit? rust/tauri is same electron except with rust. legally questionable "open-source" label?

Muhammad523

Brought to you, once again, by Claude Has it become a trend to pick up some proprietary software and vibecode a replacement for it and then slap a FOSS license on it?

Slopsidian.

I liked when it happened to Adobe, but I don't like this.
