If you work with 3D on the web — Three.js, React Three Fiber, Babylon.js, or you're exporting assets from Blender, Unity, or Godot — you've probably needed a quick way to open a .glb or .gltf file, check it looks right, or grab a clean screenshot of it without spinning up a whole project.
That's exactly why I built GLBKit — a free, no-login, browser-based toolkit for GLB/GLTF developers.
The problem
Every time I needed to sanity-check a 3D model, I ended up doing one of these:
Dragging it into a random online viewer with ads and low limits
Spinning up a local Three.js scene just to preview one file
Manually setting up lighting/camera in Blender just for a screenshot
None of these are fast. GLBKit is meant to remove that friction — drop a file in, see it instantly, and optionally export a render.
What GLBKit does
GLB Viewer
Open and inspect .glb, .gltf, and .zip (packed asset) files directly in the browser. Real-time 3D rendering with orbit controls — no upload-and-wait, no login.
GLB Screenshot
Turn any .glb/.gltf/.zip model into a high-quality render. Export as PNG or JPG, up to 4K, with optional transparent background — useful for thumbnails, marketplace listings, or docs.
More tools (optimizer, converter, and support for additional 3D formats) are actively being added.
Who it's for
GLBKit is built for the whole GLB pipeline, regardless of where your models come from:
Blender exports
Three.js / React Three Fiber scenes
Babylon.js projects
Unity and Godot asset pipelines
Raw WebGL / WebGPU workflows
If your day involves .glb files, there's a good chance GLBKit saves you a step.
