The Verdict
Gamma is built for professionals and educators, with a focus on ai-generation and responsive-design. Spline targets web designers and product designers and leads with 3d-modeling and real-time-collaboration.
Pricing is close: Spline starts at $9/mo versus $10/mo for Gamma — not a deciding factor on its own.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
