Key features
  • Inspect 3D mesh geometry and measurements
  • Repair duplicate faces and degenerate triangles
  • Fix incorrect face orientation
  • Close small triangular holes
  • Handle selected self-intersections
  • Compare before and after repairs
  • Optional uniform scaling of models
  • Download repaired STL files
  • Process files up to 50 MB
  • Local browser processing with no file upload
  • Mesh Simplification: reduce triangle count with quadric-error decimation while preserving silhouette
  • LOD Chains: generate multiple detail levels from one high-poly asset
  • Watertight Rebuild: close holes and rebuild surfaces on damaged models
  • Mesh Inspection: detect non-manifold edges, holes, winding, missing UVs and platform compatibility
  • 3D File Converter: convert between OBJ, STL, PLY, OFF and GLB formats
  • 3D Model Viewer: inspect models with orbit controls, grid and wireframe
  • 3D GIF Maker: export rotating GIF or MP4 turntable animations from models
  • REST API: programmatic access for scripts and asset pipelines
  • MCP server: AI client integration for agents like Claude
What makes it different
  • Runs entirely in your browser with no file uploads to servers
  • Free with no account or subscription required
  • Open-source software under GPL-3.0-or-later license
  • Conservative repair approach preserving original design intent
  • Real-time before and after visualization of repairs
  • Queue-backed pipeline with Postgres state tracking maintains work across device refreshes and crashes
  • Data privacy: models never used for ML training, stored in private object storage with signed expiring downloads
  • Owned hardware infrastructure with zero-egress storage keeps economics viable for large 3D files
  • Same account and allowances across Studio, REST API and MCP interfaces
  • Processing split by tier: paid work runs on dedicated workers not held up behind free traffic
