Spline
Spline is a free browser-based 3D design software that facilitates real-time collaboration for creating interactive web experiences.
"Like Xspiral but focused on free browser-based 3D design for interactive web experiences."
Teams that want real-time collaboration for web-ready 3D work and cost control.
Sends you ahead of Xspiral on cost and browser simplicity for quick interactive demos with real-time teamwork.
If you need the broader 2D/3D tooling and AI features of Xspiral, Spline may fall short.
