Spline

Spline bridges web design and 3D, positioning itself as an accessible alternative to traditional 3D packages for interactive web experiences. Users model, texture, light and animate scenes in the browser, then publish them as embeds or exports for websites and apps.

Compared with Blender, Spline offers far less modeling and rendering depth but a much shorter learning curve and native web interactivity. Its multiplayer editing model resembles Figma, which helps product teams adopt it, and AI features add prompt-based object and texture generation.

Trade-offs include runtime performance on complex scenes and limits on the free plan, including branding and export restrictions. Paid tiers start at $12 per month. For teams that need interactive 3D on the web rather than film-grade rendering, it is a pragmatic choice.
