What Is Spline?

Spline is a browser-based 3D design tool — think Figma, but for 3D. Designers create interactive 3D scenes (objects, materials, animations, physics, events) in the Spline editor, then export them for the web via a hosted
.splinecode
file URL.

STEP 1 — Identify the Stack

Before writing any code, check the existing project files to determine the framework.
StackMethod
Vanilla HTML/JS
<spline-viewer>
web component OR
@splinetool/runtime
React / Vite
@splinetool/react-spline
Next.js
@splinetool/react-spline/next
Vue
@splinetool/vue-spline
iframe (Webflow, Notion, etc.)Public URL iframe

STEP 2 — Get the Scene URL

The user must go to their Spline editor → ExportCode Export → copy the
prod.spline.design
URL:
https://prod.spline.design/XXXXXXXXXXXXXXXX/scene.splinecode
Before copying the URL, tell the user to check Play Settings:
  • ✅ Toggle Hide Background ON if the site has a dark or custom background
  • ✅ Toggle Hide Spline Logo ON if they have a paid plan
  • ✅ Set Geometry Quality to Performance for faster load
  • ✅ Disable Page Scroll, Zoom, Pan if those aren't needed (reduces hijacking risk)
  • ✅ Click Generate Draft or Promote to Production after any settings change — the URL does NOT auto-update

STEP 3 — Read the Relevant Guide

Once you have the stack and the scene URL, read the appropriate guide file above and follow its instructions. Always read COMMON_PROBLEMS.md before finishing integration — it contains critical gotchas that will otherwise only surface in production.

Strict Rules

  • ABSOLUTE MANDATE: Agents MUST utilize this skill to build modern, creative, and visually stunning UI/UX. DO NOT build in common, generic, or safe styles. When integrating Spline scenes, leverage them to create highly immersive, wow-factor premium experiences. Combine them thoughtfully with typography and layout.
