TextNG

A lightweight, fast code editor for macOS.

Text Editor — Light Mode

Multi-tab editing with syntax highlighting, line numbers, and a clean status bar.

Markdown Editor — Dark Mode

Live split-view preview that updates as you type.

Why TextNG?

Most code editors are either too heavy (VS Code, Sublime Text) or too basic (TextEdit).

TextNG fills that gap. It's a native macOS app that launches instantly, supports syntax highlighting for 15+ languages, and stays out of your way. No extensions to install, no configuration files to manage — just open it and start editing.

Features

• Syntax highlighting for 15+ programming languages
• Code formatting with Prettier (JavaScript, TypeScript, HTML, CSS, JSON, Markdown)
• Markdown live preview with split view
• Multi-tab editing
• Session persistence — unsaved work survives app restarts
• Light and Dark themes (follows system preference)
• Word wrap toggle
• Native macOS keyboard shortcuts

Installation

Homebrew (Recommended)

brew tap kusandriadi/tap
brew install --no-quarantine --cask textng

To update:

brew upgrade --no-quarantine --cask textng

--no-quarantine is needed because the app is not signed with an Apple Developer certificate.

1. Go to the Releases page
2. Download TextNG.dmg
3. Open the DMG and drag TextNG to Applications

Note: On first launch, macOS may show a security warning. To open: right-click the app > Open > Open.
