The short version

  • Only OnShape has a free tier, so it costs nothing to try first.
  • Each has a real cost: MoI (Moment of Inspiration) it is developed by one person, so releases are years apart and there is no support organisation to escalate to when something blocks your work.; OnShape the free plan is non commercial only and makes every document publicly accessible, so nothing designed on it can be kept private
  • They diverge on capability: MoI (Moment of Inspiration) covers Direct NURBS modelling, OnShape covers Cloud-native CAD.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

MoI (Moment of Inspiration)

  • It is developed by one person, so releases are years apart and there is no support organisation to escalate to when something blocks your work.
  • There is no parametric history and no assembly structure, so a late design change means remodelling rather than editing a feature.
  • It produces no dimensioned drawings or manufacturing documentation, so anything heading for production needs a second package for the paperwork.
  • Exchange is limited to surface formats such as STEP and IGES with no native interoperability with mainstream MCAD systems, so it sits at the edge of an engineering pipeline rather than inside it.
  • Each major version is a fresh purchase, and the long gaps between versions mean a fix or a feature you need can be several years away with no interim release.

OnShape

  • The free plan is non commercial only and makes every document publicly accessible, so nothing designed on it can be kept private
  • The Standard plan is $1,500 per user per year and Professional $2,500
  • Simulation, rendering, CAM and advanced PDM all require the Professional plan
  • SSO, analytics and advanced administration are Enterprise only with no published price
