Syntax Highlight for Mac

Quick code previews on macOS

Syntax Highlight is a free Quick Look extension for macOS that makes it simple to inspect source files from the Finder. Instead of launching a full editor, you can preview code files with colorized syntax right in the Quick Look pane, which speeds up browsing and reduces context switching when working with multiple files.

Benefits for developers

• Reduces the need to open files in an editor, saving time when scanning project folders.
• Improves readability of snippets by applying language-specific coloring and formatting.
• Lightweight and free to install, so it doesn’t add bloat to your workflow.
• Integrates directly with Finder, keeping previews quick and unobtrusive.

Languages supported

• JavaScript
• C++
• HTML and CSS
• Python
• Go
• Java
• Ruby

Recommended alternative

If you want another option to try, Detect It Easy (free) is a suggested alternative. It provides different detection and inspection features that may better fit reverse-engineering or file-type analysis use cases while remaining freely available.
