# Opensidian

> Opensidian: open-source, vault-compatible markdown notes app for Linux. Wikilinks, backlinks, graph view and Obsidian themes. Rust + Tauri v2, no Electron. Current version: 0.9.2. GPL-3.0-or-later, non-profit. Opensidian is a clean-room functional clone of Obsidian: it reimplements Obsidian's behaviour from the outside and contains none of its code. Not affiliated with or endorsed by Obsidian or Dynalist Inc.

Opensidian opens existing Obsidian vaults (a folder of markdown files plus `.obsidian/`) without converting them. Linux x86_64 builds ship as slim and portable AppImages, a Flatpak, an RPM and a DEB; every release has a GPG-signed `SHA256SUMS`. The full text of this site as markdown is in [llms-full.txt](https://opensidian.org/llms-full.txt).
