Detect.Expert

在本地分析浏览器 API、数字指纹迹象与身份识别服务，支持自定义 API 阻止规则。

Detect.Expert Browser fingerprinting analysis, detailed reports and configurable API blocking in one Chrome extension. Detect.Expert reveals how websites interact with your browser. Inspect fingerprinting signals, explore technical API activity, identify recognized protection services and turn your findings into clear, shareable reports. What makes Detect.Expert distinctive is the combination of live detection, technical previews, reporting and API control in a single interface, built for developers, security researchers, privacy specialists and anti-fraud engineers. Explore Fingerprinting Techniques Discover supported activity across a wide range of browser technologies: Canvas: pixel extraction, image export and calls such as toDataURL, toBlob and getImageData. WebGL and WebGPU: graphics API activity and GPU capability checks. Fonts and geometry: text measurements, font checks and page-element dimensions. Web Audio: audio contexts, offline rendering and analyser access. WebRTC: connection creation, STUN/TURN configuration, selected media parameters and certificate fingerprints. Browser and device information: User-Agent, Client Hints, screen and window properties, CPU-thread and memory queries. Permissions and interaction: browser permission checks, pointer-property reads and Idle Detection. Advanced browser capabilities: WebAssembly interface calls, timing APIs, WebNN and supported built-in AI APIs. Environment checks: Battery, Network Information, Keyboard API, Window Management and Compute Pressure. Network signals: local-port probing patterns, requested port numbers, DNS-test-like request sequences and selected response headers. Identification resources: recognized anti-fraud and protection resources, extension-resource checks, and Google / Chrome experiment IDs exposed through X-Client-Data. Explore results in the popup or Chrome side panel, with operation counters and local previews of selected technical values and Canvas/WebGL images already read by the website. Create Detailed Reports Turn browser observations into useful documentation. Start a Pro recording of up to 10 minutes to capture a browsing scenario, including visits, sanitized page titles and address templates, permitted network metadata and analysis results. Review your findings, export structured JSON, or create PDF reports through Chrome’s print dialog. Use them for technical investigations, development workflows, audits and collaboration. Control Browser APIs Go beyond observation with 15 configurable API-blocking controls. Choose controls for Canvas readback, WebGL, WebGPU, Web Audio, WebRTC, WebAssembly, local font access, Window Management, Compute Pressure, Idle Detection, Battery, Network Information, Keyboard API, JavaScript Client Hints and clipboard reading. Enable blocking when needed, configure global defaults and refine rules for individual hostnames within your permitted scope. Local By Design Analysis runs locally in your browser. You choose the observation scope, start recordings, review exports and manage saved reports. Detect.Expert brings visibility, documentation and practical API control together, helping you understand and investigate browser fingerprinting with greater precision.
