Where each one falls short

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

Spline

  • AI generation features produce inconsistent and often distorted results, failing at basic depth perception tasks
  • Limited to simpler designs - not suitable for high-poly, detailed production models
  • Performance degrades with complex scenes containing many objects and materials
  • Limited non-Apple platform coverage compared to cross-platform design tools
  • Tutorials are either too fast for beginners or too basic for advanced users

Stampli

  • Pricing is by quote only: the pricing page publishes no rate, no minimum and no cost driver, offering only a Request a Quote form
  • Payments and card products are sold alongside the core AP automation rather than being separately priced on the public site
