Nuza is a simple, lightweight alternative to Obsidian for people who just want to write and organize Markdown notes without the bloat. It is free and open source, runs on macOS, Windows, and Linux, and works directly with plain Markdown files. With built-in Vim keybindings, wiki-links, backlinks, search, frontmatter, and more, Nuza keeps note-taking fast, minimal, and fully local.
