Audit modern browser features and HTML5 capabilities online for free with our Browser Features tool. Instantly test support for WebGL, WebGPU, WebRTC, Service Workers, WebAssembly, WebUSB, Bluetooth, and storage APIs directly inside client browser RAM.
Open the page to initiate automatic client-side property probes across DOM and navigator objects.
Review the visual status grid to check enabled (✓) and unsupported (✕) browser capabilities.
Click Reset anytime to re-evaluate window object properties and hardware feature flags.
Probes modern 3D graphics (WebGL/WebGPU), background processing (ServiceWorkers, WASM), and web hardware interfaces.
Displays clean visual cards with color-coded status badges for instant capability assessment.
All API feature probes execute inside client browser memory. Zero device telemetry leaves your device.
Browser feature detection evaluates whether specific Web APIs and interface constructors exist on client runtime global environments (window, navigator). Rather than relying on user agent string parsing, runtime property evaluation ('serviceWorker' in navigator) guarantees accurate capability auditing.
Modern web applications rely on distinct API categories: 3D hardware graphics acceleration (WebGLRenderingContext, navigator.gpu), real-time peer-to-peer networking (RTCPeerConnection), low-level binary code execution (WebAssembly), and local storage engines (indexedDB).
Auditing hardware interface flags (navigator.bluetooth, navigator.usb) inside browser RAM reveals system capability flags without transmitting telemetry to external servers.
