pricing

Unity Robotics Pricing & Plans

Unity Robotics operates under a paid licensing model, leveraging the Unity game engine's subscription tiers. Specific pricing for Unity Robotics components or solutions is typically integrated into Unity's Pro, Enterprise, or Industry-specific plans, which offer various features and support levels. Unity's core engine offers a Personal plan (free for individuals/small teams under revenue thresholds), Plus, Pro, and Enterprise subscriptions. The Unity Pro plan, for example, starts at approximately $150/month per seat when billed annually, providing access to advanced features, support, and the ability to develop commercial applications without revenue limitations. Enterprise plans offer custom pricing based on organizational needs, dedicated support, and specialized tools for large-scale development.

  • Unity Personal: Free (for individuals or companies with less than $100K revenue in the past 12 months)
  • Unity Plus: ~$399/year per seat (billed annually)
  • Unity Pro: ~$1800/year per seat (billed annually, approximately $150/month)
  • Unity Enterprise: Custom pricing (for large organizations with specific needs)
