About Peeky

Peeky is a macOS Quick Look extension built to preview the files Finder leaves blank. Select one — Markdown, JSON, CSV, source code, ZIP archive, folder, image, or PSD — press Space, and the aim is a formatted preview rather than an icon and a file size. Source code is syntax-highlighted with themes, JSON is pretty-printed, CSV and TSV are drawn as tables, archives are browsed without extracting them, and folders preview as a list or a grid. A companion settings app handles fonts, themes and display options.

Who it's for

Developers who preview Markdown, JSON, and code files in Finder daily.

What it does

  • Syntax highlighting with theme support
  • Pretty-printed JSON and tabular CSV/TSV
