Overview

What it is

A better look at your files. Preview Markdown with KaTeX and Mermaid, highlight 190+ languages, view CSV and SQLite tables, browse archives and folders. All from Quick Look.

Intent

I need it when

Inspect SQLite databases and tabular data (TSV) without opening external tools

Looq opens .db files to switch between tables, page through rows, and view column types and constraints in tooltips. TSV files render as sortable, paginated native tables. This enables quick data exploration directly from Finder without database clients or spreadsheet apps.

Review code changes and diffs with clear visual distinction between old and new lines

Looq renders diff and patch files with red/green coding and paired old/new line numbers. Multi-file diffs split into tabs. This provides immediate visual feedback on changes without opening a diff viewer or terminal.

Browse source code across 200+ languages with syntax highlighting and context awareness

Looq highlights code using VS Code's grammars and themes across 200+ file types. Sticky scope headers pin enclosing functions and classes as you scroll. Hover-tracking line numbers brighten the gutter. This makes code review and inspection faster without launching an IDE.

Preview Markdown files with advanced formatting (math, diagrams, alerts) without opening a separate editor

Looq renders full GitHub-flavored Markdown with KaTeX math, Mermaid diagrams, alerts, and emoji. Live preview updates as you edit the file. Sidebar table of contents follows scroll position. This eliminates the need to open a Markdown editor or browser just to see formatted output.

Examine archive contents and folder structures without unpacking or navigating nested directories

Looq opens ZIP, TAR, GZ, BZ2 archives natively to browse contents as Finder would. Folders display in list or icon grid view, sortable by date, kind, size, or tags. This saves time and disk space by previewing archive structure before extraction.

Drop

Not a fit when

  • User works primarily on Windows or Linux; Looq is macOS-only (requires macOS 14 Sonoma or later)
  • User needs cloud-based file preview with team collaboration; Looq is 100% on-device with no cloud sync or sharing features
  • User requires real-time collaborative editing; Looq is a preview tool only, not an editor
  • User needs to preview proprietary binary formats beyond the supported types (Markdown, code, SQLite, TSV, archives, folders, app bundles); unsupported formats will not render
  • User operates in an air-gapped or offline environment and needs frequent updates; Looq requires internet access for initial download and license activation
