The short version

  • Each has a real cost: Neptune.ai free tier limited to 100 hours per month, exhausted quickly with serious ML 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: Neptune.ai covers Experiment tracking, OnShape covers Cloud-native CAD.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

Neptune.ai

  • Free tier limited to 100 hours per month, exhausted quickly with serious ML work
  • Lacks hyperparameter sweeps compared to Weights and Biases
  • No pipeline orchestration or broader MLOps lifecycle management
  • Dashboard visualization limitations - automatic resizing affects visualization order and size
  • Cloud-based SaaS only (as of last available service) requires internet connectivity

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
