PreviewCode provides QuickLook file previews and Finder file icon thumbnails for source code documents and data files for a wide variety of programming languages.

The app provides two app extensions: Code Previewer and Code Thumbnailer, which can be viewed and managed in macOS’ System Preferences > Extensions. The app itself is a container for these extensions.

You must run the app first to gain these benefits.
