3D Website Checklist — Pre-Launch Quality Gates
Comprehensive 3D website checklist: performance, accessibility, SEO, browser compat, mobile, security.
Pre-launch 3D website checklist: (1) Performance — Lighthouse mobile 85+, FCP under 1.5s, LCP under 2.5s. (2) Accessibility — prefers-reduced-motion respected, screen-reader content present, keyboard navigation works. (3) SEO — meta tags complete, schema.org markup, sitemap.xml. (4) Browser compatibility — tested on Chrome, Safari, Firefox, mobile Safari, Chrome Mobile. (5) Mobile — touch interactions work, device-tier serves correct quality. (6) Security — HTTPS, CSP headers, no exposed credentials. Time: 4-8 hours of focused QA.
Want a faster path
If your timeline is short and the project matters commercially, hiring an experienced developer often beats self-learning by 4-6 weeks of effort. I take on 3D Website Checklist — Pre-Launch Quality Gates projects on a fixed-price basis — you get the working result without the learning detour. Reach out via the contact page if a structured engagement makes sense for what you're building.
Further reading
Three resources I recommend after this guide: the official Three.js fundamentals docs (excellent and underused), Bruno Simon's Three.js Journey (paid, comprehensive), and the React Three Fiber docs if you'll work in React. Beyond that, reading other developers' source on GitHub — search for 'three-js portfolio' on GitHub trending — accelerates learning faster than any tutorial.
Prerequisites
Before starting on checklist, you need: a JavaScript baseline (familiarity with ES modules, async/await, npm), a working local dev environment (Node 18+, a code editor), and a basic mental model of what WebGL renders. You don't need 3D modeling skills — for most tutorials, the assets are provided. Time investment: 2-4 hours of focused work for the basic version.
Step-by-step outline
Step 1: scaffold the project (Vite + Three.js). Step 2: get a basic scene rendering — camera, light, geometry. Step 3: load the asset (glTF). Step 4: hook up animation timeline (GSAP or built-in). Step 5: add interactivity (click, scroll). Step 6: optimize for mobile (device-tier check, asset compression). Step 7: deploy. Each step builds on the previous; skipping leads to confusion later.
