Mx

mx

A fast, lightweight markdown editor for the AI era. Built with Tauri 2 + Rust.

**Website: [getmx.vibery.app](https://getmx.vibery.app/)**


**Coming from [MacDown](https://macdown.uranusjr.com/)?** MacDown has been abandoned since 2020 — no Mermaid support, no Apple Silicon build, no updates. mx picks up where MacDown left off: same simplicity, but with modern features like Mermaid diagrams, KaTeX math, YAML frontmatter, and a fraction of the bundle size.

macOS: "mx is damaged and can't be opened"

macOS Gatekeeper blocks unsigned apps. After installing, run:

xattr -cr /Applications/mx.app

Why mx?

Working with AI means opening dozens of markdown files every day. You need a fast editor that just works — not a vault-based system like Obsidian, not an abandoned app like MacDown. mx opens any `.md` file instantly with live preview. No vault. No config. Just open and go.
