3D Website QA Checklist — Test Before Launch
QA checklist for 3D websites: device matrix, browser matrix, accessibility audit, performance audit, content audit.
3D website QA: (1) Device matrix — iPhone 12+, iPhone SE (older), Pixel 4a, Galaxy S22, iPad. (2) Browser matrix — Chrome, Safari (desktop and mobile), Firefox, Edge. (3) Accessibility — WAVE audit, screen-reader test (VoiceOver/NVDA), keyboard nav. (4) Performance — Lighthouse on real devices, not just emulator. (5) Content — typography readable, all images load, forms submit, links work. (6) Network — test on throttled 3G to simulate slow connections. Time: 8-16 hours for thorough QA.
Common pitfalls
Three failure modes I see beginners hit: (1) trying to render before assets finish loading — always wait for the loader callback, (2) using full-resolution textures on mobile — always have KTX2 or compressed alternatives, (3) leaving the scene rendering when off-screen — pause the render loop with IntersectionObserver. Each pitfall has a clear fix; the trick is recognizing the symptom.
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 QA Checklist — Test Before Launch 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 qa 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.
