Browser Feature Detection — Check API Support
Check which of 50+ Web Platform APIs your browser supports, grouped into Graphics, Media & Audio, Network, Storage, Input, Device APIs, Performance, and Security. Each feature includes a short note on what it does and how it is tested — so you can quickly confirm whether WebGL, Service Workers, WebRTC, WebGPU, or Bluetooth will work in your current browser.
All checks run locally in your browser using standard feature-detection techniques — nothing is installed, enabled, or uploaded.
