Spline 3D Integration Skill

Master guide for embedding interactive 3D scenes from Spline.design into web projects.

When to Use

  • You need to embed an interactive Spline scene into a web project.
  • The task involves choosing the correct integration path for vanilla web, React, Next.js, Vue, or iframe contexts.
  • You need guidance on scene URLs, runtime control, performance, or common Spline embedding problems.

Quick Reference

Task Guide
Vanilla HTML/JS embed guides/VANILLA_INTEGRATION.md
React / Next.js / Vue embed guides/REACT_INTEGRATION.md
Performance & mobile optimization guides/PERFORMANCE.md
Debugging & common problems guides/COMMON_PROBLEMS.md

Working Examples

examples/react-spline-wrapper.tsx Production-ready lazy-loaded React wrapper with fallback
examples/interactive-scene.tsx Full interactive example: events, object control, camera

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.

Stack Method
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 → Export → Code 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.

Limitations

  • Use this skill only when the task clearly matches the scope described above.
  • Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
  • Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
