Spline

Collaborative browser-based 3D design tool with AI 3D generation and interactive embeds for Webflow, Framer, and Wix Studio

Spline is a browser-based collaborative 3D design tool for building interactive scenes that embed directly into websites and apps. The free plan watermarks web exports; Starter costs $12/month (annual) and removes them; Professional at $20/month adds code exports, unlimited projects, and the Hana 2D editor. AI 3D generation is a separate add-on at $5/month for 2,000 credits. Best for designers who want interactive 3D on the web without learning Blender.

What is Spline?

Spline is a collaborative 3D design tool that runs in the browser (with desktop apps for Mac and Windows) and focuses on shipping interactive 3D to the web rather than rendering stills or film. You model with primitives and parametric objects, apply layer-based materials from a ready-made library, then add interactivity through states, events, timeline animation, physics, particle systems, and game controls. Finished scenes export as JavaScript, React, Next.js, or HTML embeds, drop directly into Webflow, Framer, or Wix Studio, or compile to native iOS (Swift) and Android (Kotlin) code on the Professional plan.

The AI layer, Spline AI, is a metered add-on at $5 per seat per month with 2,000 credits: it generates 3D objects from text or image prompts, creates textures, and applies style transfer, and the results land in the same editable scene as hand-built geometry. Collaboration works like Figma — real-time multiplayer editing, in-canvas comments, and link sharing, with unlimited free viewers on every plan including Free. Professional scenes can also pull live data through variables, webhooks, and API connections, which turns embeds into functional product configurators or dashboards rather than static decorations.

Who is it for?

Spline is aimed at designers who need 3D on the web but have no interest in the Blender or Cinema 4D learning curve. The Free plan is enough to evaluate the editor, but the watermark on web exports and the file cap mean client work realistically starts at Starter ($12/seat/month annual), and code or GLTF export workflows need Professional ($20/seat/month annual).

  • Web designers and agencies adding interactive 3D hero sections, product showcases, and configurators to Webflow, Framer, or Wix Studio sites without writing WebGL code.
  • Product and brand teams that want real-time co-editing and in-canvas review of 3D assets, with stakeholders viewing for free on any plan.
  • App developers exporting scenes as native Swift or Kotlin code, or connecting scenes to live data through variables and webhooks on Professional.
  • Designers experimenting with AI 3D generation who want text-to-3D and texture generation inside an editor they can refine in, at 2,000 credits for $5/month instead of a standalone generator subscription.

Pros and cons

Pros and cons of Spline
Pros Cons
Design-tool interface aimed at designers rather than 3D specialists — no Blender-style learning curve for web-focused 3D work AI features are excluded from every base plan — even paid users must add $5/seat/month, and heavy texture generation or style transfer can burn through the 2,000 monthly credits
Direct embed pipeline into Webflow, Framer, and Wix Studio, with unlimited viewers on every plan including Free Free plan watermarks all web exports and caps the number of files, so anything client-facing effectively requires Starter or above
AI add-on is inexpensive at $5/seat/month for 2,000 credits compared to standalone AI 3D generators Scenes render in real time in the viewer's browser, so complex projects with physics and particles depend on the visitor's hardware and add page weight
Real-time multiplayer editing and in-canvas comments work like Figma, so team review needs no file passing Code, GLTF, video, and native iOS/Android exports are gated behind Professional at $20/seat/month; Starter only covers web and image exports
Modeling is built around primitives and parametric objects — it is not a replacement for Blender or Cinema 4D in high-poly sculpting or offline photoreal rendering pipelines
