Cortex Code
A beautiful, lightweight code editor for macOS.
Cortex Code is a fast, minimal code editor built in Swift for macOS — the newest member of the Cortex family. It pairs tree-sitter-powered syntax highlighting with familiar workspace chrome (activity bar, file explorer, command palette, quick open) and the signature Aurora animated background with Liquid Glass UI shared across the Cortex line.
$ swift run CortexCode What it does
Tree-sitter highlighting
Grammar-accurate, structural code coloring — Swift and JSON via tree-sitter, with fallbacks for many more.
Familiar workspace
Activity bar, lazy file explorer, editor tabs, command palette (⌘K), quick open (⌘P), and find in file.
Aurora + Liquid Glass
The same breathing gradient background and glass UI as the rest of the Cortex family, for visual depth.
Pure Swift, no bloat
A native NSTextView editor built as a Swift package — no Electron, no Xcode project required.
