.blend URL Viewer renders Blender 5.x files in the browser from a URL or GitHub link
↗
Simon Willison released a browser-based viewer that renders Blender .blend files from CORS-accessible URLs or GitHub links, supporting mesh geometry, materials, lighting, and saved camera positions.
The tool lets you inspect Blender models without opening the Blender application, which is useful for reviewing AI-generated 3D assets quickly. Willison demonstrated it by viewing a Blender model that Codex running GPT-6 Astra generated from an image prompt in roughly 18 minutes. Only one feed carries this, so the tool's capabilities are described solely by its author.
