Pricing modelFreemium Freemium
PricingLocal checker: $0 / file. Private repair & export: pay as you go after launch with credits. Free: $0 with account or no account required (10 processing credits per 24 hours, up to 50 MB per file, 250 MB storage). Starter: $15 per month (500 processing credits per month, up to 250 MB per file, 5 GB storage, 7-day free trial). Pro: $35 per month (2500 processing credits per month, up to 1 GB
Key features
  • Local browser STL parsing of binary and ASCII files
  • Five core mesh issue detection families
  • Conservative repair preview for safe fixes
  • Mesh health score and detailed issue report
  • Sampled mesh projection visualization
  • JSON repair report download
  • File size limit up to 10 MiB
  • Triangle limit up to 100,000
  • 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
  • No file upload required—all processing runs locally in your browser
  • Conservative repair approach with verified output before download
  • Free indefinitely for local browser checks
  • Clear boundary between what the tool fixes and what requires manual review
  • 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
