OpenMark vs VS Code
A dedicated markdown editor vs a code editor
VS Code is an excellent code editor. But it's an Electron app weighing 300MB+, and markdown support requires extension hunting. OpenMark is purpose-built for markdown on macOS — native SwiftUI, instant launch, Mermaid and LaTeX built-in. Here's how they compare for markdown editing specifically.
