Our review
Pros
  • Free interactive 2D and 3D topology optimization
  • Multiple load cases, gravity, and passive solid or void elements
  • MATLAB, Python, PETSc, COMSOL, and Grasshopper integrations
  • Combines optimization, uncertainty quantification, and sensitivity analysis methods
  • Connects analysis codes to iterative systems-analysis methods
  • Offers a Python interface and Windows, macOS, and Linux support
Cons
  • More a collection of apps and codes than a conventional SaaS product
  • Manufacturing workflow coverage is narrower than its optimization scope
  • Advanced workflows may require MATLAB, Python, C/C++, or research codes
  • Focuses on computational-model analysis rather than geometry generation
  • Requires analysis codes or models to connect to its methods
  • Support is through community and documentation
