KeyShot

  • Professional plan costs £108.25/month per user; total cost for small teams can be substantial
  • 3-year commitment reduces to £3,897 per user, but locks in pricing for extended period
  • Network Rendering, Studio VR, and Cloud Rendering are paid add-ons (£29-£99/month additional)
  • No clear platform support information; likely Windows-only based on CAD tool integrations
