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.
Hey everyone! I'm the developer behind Looq.
I built Looq because Quick Look on macOS handles images and PDFs great, but falls flat for everything else developers touch daily. Press Space on a Markdown file, a .swift file, or a SQLite database — you get raw text or a blank panel. I kept opening full editors just to glance at a file, and it added up.
Looq is a single Quick Look extension that previews:
Markdown — full GFM, KaTeX math, Mermaid diagrams, GitHub Alerts, auto TOC
Source code — syntax highlighting for 190+ languages, auto-formatting for minified JSON/CSS/XML
Data files — CSV and SQLite as native sortable tables with column headers and type info
Archives — browse ZIP/TAR contents without extracting
Diff/Patch — color-coded with dual line numbers
Everything runs locally on your Mac. No analytics, no telemetry, no accounts.
What file types or features would you want to see next?
Nice idea !! extending Quick Look for dev files makes a lot of sense. @parcse
Would be cool to see support for log files or very large files too : is that something you're planning to add?
The Mermaid diagram preview sold me instantly. I write a lot of docs in Markdown and always have to open a separate editor just to check if the diagrams render correctly. Does it support live-reloading, like if I edit and save a file while Quick Look is open?
