Polynite

About Polynite

Polynite is a 3D tool that runs in a browser tab. It opens GLB files, renders them with WebGPU, and makes them smaller.

Why a browser

Most people who need to check or shrink a GLB do not want to install anything, and the ones who already own a 3D suite do not want to open it to answer a question that takes ten seconds. A page that loads, reads the file locally and draws it removes that whole step. WebGPU is what makes it viable: the same cluster based renderer that would need a native build a few years ago now runs on a tab.

What it does today

View

GLB first, and debug views for normals, depth, UVs, clusters and level of detail. OBJ and text glTF open too.

Optimize

Geometry quantization, Meshopt compression, texture resampling, and a side by side comparison before you export.

Simplify

Error driven edge collapse with UV and boundary constraints, and several quality steps from one source.

Keep

An optional library backed by your own GitHub account, so a model you publish follows you from one machine to the next.

Where it is going

Scene editing, animation and rigging, procedural generation, and AI assisted tools through MCP are on the way. They are not here yet, and this page will say so until they are.

Your files

Models you open are read by the page and stay on your machine. Signing in is optional and is never required to view or optimize anything. When you do sign in, Polynite stores what you publish in a repository you own and can take back at any time.

Who makes it

Polynite is built by a small independent team. The source of several components, including the connectors, is published on GitHub.
