Quick Look plugins

Quick Look Plugins is a curated directory of macOS extensions and applications that expand the file formats Finder can preview through Quick Look. It is aimed particularly at developers who frequently inspect source code, configuration files, archives, documents, and specialized technical formats without opening full applications. The collection includes tools for Markdown, JSON, plain text, source code, archives, application bundles, installer packages, video, provisioning profiles, and various image formats. It also lists more specialized previewers for chemistry files, 3D-printing models, folders, and mathematical Markdown. Both free and commercial options are included, with installation information provided through Homebrew or manual installation where applicable. The repository functions as a maintained reference catalog rather than a single Quick Look extension.
