Hello, I am Aniruddha, a developer. When I move 3D files between Blender, a slicer and a web page, I keep needing small jobs: open an STL to check it, convert OBJ to GLB, look at the size of a mesh, or share a model with someone who has no Blender installed.
I built OpenFile, a free and open source (MIT) toolkit with 360+ file tools, and it has a group of 3D tools that run entirely in the browser with WebAssembly and WebGL. Nothing is uploaded, so unreleased client models stay on your machine, and it works offline as an installable app. The rest of the toolkit covers PDF, images, video, audio and fonts, which helps when you also need to resize textures or compress renders.
I want honest feedback from people who work with meshes every day. Which formats or checks are missing, and what would make a browser viewer useful in your pipeline? Bugs and ideas welcome on GitHub.
