Browser benchmark tests

Array Test Runs deterministic array workloads covering prime-number sieving, transformations, sorting, searching, mutations, flattening, spread operations, and typed arrays. v1.0 › Bitwise Test Runs deterministic integer workloads covering bitwise logic, bitmasks, pixel packing, hashing, bit counting, binary data, and combined stress operations. v1.0 › Built-in Objects Test Exercises native JavaScript objects and APIs, including collections, typed arrays, buffers, promises, Proxy and Reflect, internationalization, and modern utilities. v1.0 ›

WebGL 2.0 Test Renders 1,060 frames of a detailed 3D scene through WebGL 2 at a fixed 1920 x 1080 internal resolution and measures frame throughput. v1.0 › WebGPU Test Renders 1,060 frames of a fixed 1920 x 1080 physically based 3D scene through WebGPU and records frame throughput and available adapter data. v1.0 › Shader Pipeline Test Measures browser and GPU throughput while rendering a fixed 3D scene with seven WebGL shader configurations. v1.0 › Draw-call Stress Test Adaptively increases draw calls, finds stable throughput near 70% of detected peak FPS, and scores the selected draw-call workload with its measured FPS. v1.0 › Geometry Stress Test Adaptively increases terrain tessellation, samples stable FPS at each density, and reports the peak geometry workload and its measured frame rate. v1.0 › Canvas Test Measures Canvas 2D rendering throughput with a fixed 15-second physics scene at 1000 x 600. v1.0 › SVG Test Measures how quickly the browser applies a fixed sequence of zoom, pan, and matrix transformations to a detailed SVG map. v1.0 ›

jQuery Test Measures how quickly the browser completes a fixed jQuery 3.7.1 UI workload spanning DOM updates, SVG content, and a virtualized image grid. v1.0 › Angular Test Measures how quickly the browser completes a fixed Angular 20 workload spanning large view updates, reactive SVG, and a virtualized image grid. v1.0 › Vue.js Test Measures how quickly the browser completes a fixed Vue 3 workload spanning reactive views, SVG updates, and a virtualized image grid. v1.0 › React.js Test Measures how quickly the browser completes a fixed React 19 workload spanning component views, SVG updates, and a virtualized image grid. v1.0 › Svelte Test Measures how quickly the browser completes a fixed Svelte 5 workload spanning reactive views, SVG updates, and a virtualized image grid. v1.0 › Crunch Test Stresses browser DOM and CSS processing by inserting highlighted text, validating computed styles, and removing temporary elements. v1.0 › DOM Search Test Searches a deterministic 2,500-item DOM tree with lookup, selector-matching, and tree-traversal APIs. v1.0 › DOM Create Source Test Builds and mutates deterministic 2,500-item DOM workloads using multiple element-construction and update techniques. v1.0 ›

CSS Capabilities Evaluates browser support for 74 established CSS capabilities and reports 24 limited-availability features separately. v1.0 › HTML5 Capabilities Checks 61 established HTML and web-platform capabilities with safe local probes and reports 20 limited-availability capabilities separately. v1.0 › Page Load and Responsiveness Capabilities Measures scripted UI responsiveness with a deterministic 96-record workload in a fixed 1280 x 720 viewport and records page-load diagnostics separately. v1.0 › Responsive Layout Capabilities Tests responsive layout correctness under controlled mobile, tablet, and desktop size changes using integrated layout and resize behaviors. v1.0 ›
