About
Looq is a powerful extension to the standard Quick Look feature on Mac.It replaces the basic file preview (opened by pressing spacebar in the Finder) with a full-featured viewer that understands dozens of additional formats, from Markdown and code to SQLite databases, archives and application metadata.
Install the extension → highlight any file in Finder → press Space.Instead of a basic preview, a full-featured preview will open with rendering, syntax highlighting, navigation and interactive elements - all without opening heavy applications.
Unlike the built-in Quick Look, Looq adds a full interactive preview for:
Markdown files
• Full support for GitHub Flavored Markdown.
• Table of contents on the side that tracks scrolling.
• Mathematics KaTeX (within lines and in separate blocks).
• Mermaid diagrams (BeautifulMermaid + mermaid.js combination is used for all types of diagrams).
• GitHub-styled alerts and emoji shortcodes.
• Live update while editing a file - no flickering.
Source code (over 200 file types)
• Syntax highlighting with the same grammars and themes as in VS Code.
• “Sticky” scope headers (for example, the name of a function or class remains attached to the top when scrolling).
• Line numbers that highlight the current line under the cursor.
• Support for shebang scripts and configuration files.
SQLite database
• Opening .db files without additional tools.
• View tables, switch between them, paginate by row.
• Tooltips with column types and restrictions.
• Work even with tables with a million rows - data is loaded in portions.
Tables (TSV/CSV)
• View TSV files as a native AppKit table.
• Sortable columns, pagination.
Diff/Patch files
• Visual display of changes: red/green code.
• Paired numbers of old and new lines are next to each other.
• Multi-file diffs are divided into tabs.
Archives without unpacking
• View ZIP, TAR, GZ, BZ2 content.
• Display the structure in the same way as the Finder would show it.
Finder-like folders
• View folders as a list or grid of icons.
• Sorting and grouping by date, type, size, tags.
Application and installer metadata
• View information about code signing, entitlements, notarization for: .app, .ipa, .pkg, .dmg, .iso, .torrent, as well as provisioning and configuration profiles.
