Set the scan scope, start the scan, then export the report or add it to compare.

All checks use browser-available APIs. Some hardware, GPU, network, battery, and other fields may be affected by system permissions, browser policies, and privacy settings. “Unavailable” is normal.

Instructions

Software Usage Instructions

Set the detection scope: After entering the tool, first select the items you want to detect in “Detection Settings”. You can enable local fingerprint summary, Canvas hash, battery information, media device statistics, network latency probing, and screen refresh rate estimation.
Configure export parameters: Set the file name prefix, default export format, and whether to include a timestamp in the file name. After setup, you can click “Save Settings”, and they will be applied automatically the next time you open the tool.
Start detection: Click “Start Detection and Proceed to Next Step”. The tool will read information about the current device’s system, browser, screen, graphics, network, storage, privacy, and feature support.
View detection results:
- Summary information: Quickly view the device type, system, browser, screen, and GPU information.
- Grouped details: View details grouped by system and hardware, browser, display and screen, graphics and GPU, network, storage, battery, media devices, browser capabilities, privacy, and fingerprint.
- Search and filter: Enter keywords such as Chrome, WebGL, resolution, or memory to quickly locate related fields.
- Copy content: Copy a single field, a group, or the current device summary.
Parse UA string: You can paste a User Agent string in “Detection Settings” and click “Parse UA” to view the corresponding system, browser, device type, and rendering engine.
Export the current report: In “Export Comparison”, select JSON, TXT, CSV, XML, HTML, or Markdown format, then click “Download Current Report” to save the detection results.
Package multi-format reports: Click “Download Multi-Format Package” to generate multiple formats at once and compress them into a ZIP file.
Compare multiple devices: Click “Add to Comparison List” to save the current detection results, or import multiple JSON report files. The interface only displays the first 20 file names, but all files will be read during processing.

FAQ

A: Some information depends on system permissions, browser policies, and privacy settings. For example, fields such as device memory, network type, battery status, and media device labels may not be readable in certain environments. This is normal.

A: The CPU core count and memory come from system-provided APIs and may be processed by the browser. Memory is usually an estimate, and the core count may also be lower than the device’s actual specifications due to privacy protection or runtime environment restrictions.

A: WebGL GPU information can be used to assess graphics rendering capabilities, maximum texture size, WebGL version, and renderer name. It is suitable for web compatibility checks, graphics feature troubleshooting, and device capability records.

A: The device fingerprint summary is calculated from several device and environment fields and is used to compare different detection results locally. It is not an account, password, or identity document, but it is still sensitive technical information, so it is recommended to use and share it only in trusted scenarios.

A: JSON, TXT, CSV, XML, HTML, and Markdown are supported. JSON is suitable for programmatic reading, CSV for organizing tables, TXT and HTML for human viewing, XML for data exchange, and Markdown for document records.

A: First export a JSON report on each device, then return to “Export Comparison” and import these JSON files. The tool will generate a comparison list and can export a CSV or ZIP report package.

A: The number of audio input devices, audio output devices, and cameras can usually be counted, but device names may only be displayed after permission is granted. When not authorized, showing the count or “Unavailable” is common behavior.
