Browser-based 3D design that exports to the web — with AI generation as a paid add-on.
Pricing
Verified 14 Jul 2026· sourceOverview
Spline is a 3D design tool for people who are not 3D artists. It runs in the browser, the interface borrows more from Figma than from Blender, and its real purpose is producing interactive 3D that ships on a website — hero scenes, product spinners, animated widgets, with code export and event handling built in. Designers who bounced off traditional 3D software get productive here in an afternoon, which is not a small claim. The AI capabilities are worth being precise about: text-to-3D generation, texture generation and style transfer are an optional paid add-on with its own monthly credit allowance, not something bundled into the base tiers. Treat Spline as a 3D design tool with AI attached rather than an AI tool. Its limits show when you push it: complex scenes get heavy in the browser, it is not a modelling package for detailed organic geometry, and the free plan watermarks web exports and caps files. Excellent for web design; wrong for production 3D pipelines.
