Mac
Press Space on code, Markdown, data, archives, fonts or 3D models and see them laid out with care. Free for code and documents. Your files never leave your Mac.
Press Space on the files you work with every day and see them properly. Showglass brings rich Quick Look previews and Finder thumbnails to 83 file types in 13 families, in one clean design that feels at home in light and dark.
CODE AND DOCS
Syntax-highlighted code with line numbers and an outline of every function and section. Config files that are easy to read. Markdown set like a real document, with tables, task lists, a table of contents and highlighted code blocks.
DATA, LAID OUT
JSON, XML and property lists as trees you can fold. TSV and JSON Lines as tables with a summary of every column. SQLite databases and Parquet files with their schemas. Jupyter notebooks with their cells and outputs.
ARCHIVES, WITHOUT UNPACKING
Look inside ZIP, TAR, gzip, xz, bzip2, 7-Zip, RAR, JAR, IPA and APK files: a file tree with sizes, and nothing extracted. EPUB books with cover and contents, and comic archives as a page strip.
FONTS AND 3D
Font specimens with the glyph grid, metrics, variable axes and language coverage. glTF, GLB, FBX and 3MF models you can turn around, with real dimensions, materials and counts.
AND MORE
- Developer files: String Catalogs, entitlements, logs, crash reports, diffs, HAR files and model weights (GGUF, safetensors, NumPy).
- Design files: Sketch, Procreate and Krita documents with their embedded previews and layers, plus QOI images.
- Media: tracks, codecs and chapters of Matroska and WebM files, and SRT, WebVTT and ASS subtitles as a timeline.
- Maps: GPX, KML and GeoJSON routes with distance, climb and an elevation profile.
- Folders: an image grid, a breakdown by kind and the largest files.
- Apps: version, signature, architectures, the permissions they ask for and what is inside.
THUMBNAILS THAT SHOW WHAT'S INSIDE
Finder icons for archives, config files, stylesheets, subtitles and data show their real contents, so you can tell files apart before you open them.
THE SHOWGLASS APP
In the app, search by type or extension to see how Showglass previews a file, drop a file on the window to try it, and choose from six color themes. Every family comes with a sample you can open in one click.
FREE AND PRO
Showglass is free, with every feature of the app. 30 file types are free: code and config, Markdown and docs, JSON5 and JSONC. Showglass Pro, a one-time in-app purchase, unlocks the rich views for the other 53 types and five extra color themes.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Showglass 1.2
- Four preview looks with Pro: Folio, Ledger, Vitrine and Atlas give every preview a new layout and type. Pick one in Settings > Themes.
- MKV and WebM play in Quick Look: turn on Showglass's media extension (the app shows you how), then press Space on a Matroska or WebM file to watch it, with its tracks beside the picture.
- Tables you can work with: sort from a column's header, see empty values in each column's profile, and copy rows as CSV, Markdown or JSON.
- Faster code: outline clicks jump at once, colors stay on large files, and the Print theme now colors code in printer's inks.
- Open any file in Showglass: use Open With, the Dock icon, Services or Shortcuts to see a file in its own window.
- Filter with a click: logs by level, archives by kind and extension, tables by a column's most common values.
- Logs open at the end, with First error and Last error. Select several archive entries and copy their paths with Command-C.
- Lighter on big files: Markdown shows GitHub alerts as callouts, and large Markdown, Parquet, subtitle and diff files take less time or memory to open.
