Spline gives designers a browser-based 3D editor whose output drops into a website as an embeddable scene, no game engine required. For the interactive 3D hero sections that marketing teams keep asking for, it is by far the shortest path from idea to shipped. Collaboration works like a design tool rather than like a 3D package.
Who it is for
A brand designer who needs an interactive 3D hero section on a marketing site without a game engine.
Key features
- Browser-based 3D scene editor
- Exports as an embeddable web component
- Interactive events and physics
- Collaborative editing like a design tool
- Free tier adds Spline branding
- Export limits on lower plans
Where it falls short
Exported scenes are heavy enough to hurt page performance on mobile, and the free tier limits exports and adds branding, so production use starts at the paid tier.
Pricing
Free tier includes limited exports and Spline branding; paid plans are per editor and start around $9 a month, with export count and file size as the gates.
Prices move; the tier structure is the part that stays true. Check current pricing on Spline.
