MeshCrunch reduces polygon count and generates LOD chains for 3D models, exporting to OBJ, STL, GLB, PLY or OFF so game and web-XR scenes load faster. Mesh inspection, format conversion and the 3D viewer run free in your browser with no account; simplification and LOD generation run on their servers and cost processing credits. It also offers a REST API and an MCP server so scripts or an AI agent like Claude can queue the same jobs on assets already in your account.
What holds up
- +Mesh inspection, conversion and viewing run free in-browser with no account needed
- +States plainly it never trains ML models on uploaded files
- +MCP server lets an AI agent price, run and read optimization jobs directly
- +Rejects unsupported formats on upload instead of failing partway through a job
Mind the limits
- −Simplification and LOD generation cost processing credits, unlike the free browser tools
- −Free-account files are deleted after 7 days, or 24 hours if you never sign in
