The fastest way to preview 3D models on your Mac. Quick Look thumbnails, full inspector, scene graph, and animations, all in one clean app.
Miru - see inside your 3D models.
Miru is a fast, focused 3D model viewer for Mac. Whether you're a designer reviewing assets, a developer debugging a pipeline, or just curious what's inside that file someone sent you, Miru opens 3D models instantly and gives you everything you need to inspect them, without launching a heavy modeling app.
Built for the way Mac works
Miru integrates deeply with macOS. Press Space on any supported file in Finder to get a live, interactive 3D preview right inside Quick Look, rotate, zoom, and pan without ever opening the app. Double-click to open the full inspector, drag files onto the Dock icon, or set Miru as your default handler for instant access.
A clean, focused inspector
Open a model and you get a clean window built around the 3D scene itself. Drag to rotate, scroll to zoom, option-drag to pan, all the camera controls feel natural from the first second. The sidebar shows the full scene graph with cameras, lights, meshes, and groups clearly labeled. Tap any node to inspect it. A live HUD displays mesh count, material count, and triangle count so you always know what you're looking at.
Animation playback
Models with embedded animations are detected automatically. A animation bar appears at the bottom of the window with play, pause, and a picker for switching between clips. Watch your models in motion exactly as the artist intended.
Native macOS design
Miru is built with the latest macOS technologies and feels like it belongs on your Mac. Liquid Glass surfaces, smooth animations, great icons throughout, and a thoughtful dark interface that lets your models take center stage. The App also remembers everything you've viewed, so picking up where you left off takes one click.
Supported formats
Miru reads standard 3D model files in both text and binary form. Self-contained binary files preview perfectly everywhere, including in Quick Look. Text-based files with external resources open in the full app.
Privacy and performance
Miru runs entirely on your Mac. No accounts, no telemetry, no cloud, your files stay where they are. Built natively for Apple Silicon and tuned for fast load times, even on large multi-mesh assets.
Who it's for
- 3D artists checking exports before delivery
- Game developers verifying pipeline output
- Web and AR developers working with model files
- Anyone who's ever received a 3D file and wished it just opened
Miru does one thing well: it shows you what's in a 3D file. Quickly, beautifully, and without getting in your way.
