Launch websites with enterprise needs at startup speeds.

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?

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?

@ray_artlas Thanks! Right now you'd need to press Space again after saving to refresh the preview. Auto-refresh on file change is on the roadmap — it's a great use case for Mermaid workflows and I want to get it right.

Auto-refresh on file change will land in the next release.
