QLColorCode for Mac

Quick code previews for macOS

QLColorCode is a Quick Look extension for macOS that lets you inspect source files with colorized syntax without launching a dedicated editor. It renders code in a readable, highlighted format so you can skim through scripts and snippets directly from Finder.

Main advantages

• Instant previews through Quick Look: select a code file and press the spacebar to see a highlighted view.
• Broad language compatibility so many different file types display with proper syntax coloring.
• Minimal disruption to your workflow — ideal for fast checks or comparing small sections of code.
• Free to use, integrating smoothly into the macOS experience without extra overhead.

How to use it

1. Install the QLColorCode plugin following the package instructions.
2. Quit and relaunch Finder if required, then locate a source file.
3. Highlight the file and press the spacebar to open the Quick Look preview with syntax highlighting.

When it’s most useful

QLColorCode is great for developers or anyone who frequently inspects plain text code: quick reviews, spotting syntax at a glance, or confirming file contents without opening a full IDE.
