Choose Spline if you want the more established, widely-adopted pick that most people reach for first, and you prefer a focused 3D & motion tool that does its core job exceptionally well.
Pricing & how you'll pay
GSAP and Spline use broadly similar pricing models, so cost is unlikely to be the deciding factor. Focus instead on which one fits your workflow — and always confirm the latest plans on each site, since pricing changes often.
Workflow & learning curve
The best 3D & motion tool is the one that disappears into your routine. Think about which interface feels more natural to you, which integrates with the apps you already use, and which you'd actually open every day. A short free trial of each tells you more than any feature chart.
Scope — all-rounder or specialist
GSAP stretches across more of the workflow, which is handy if you want fewer tools to juggle. Spline is more focused, which often means it does its core job better. Decide whether you want breadth or depth.
Momentum & community
