Browser Detector Toolv1.0.0

Run a full client-side check to detect your browser, operating system, device characteristics, and web platform features. Use the results to troubleshoot issues, validate environments for QA, and share clear specs with support.

• Click Check Browser to run detection and refresh high-entropy values when available.
• Review Browser Details and Screen Details for name, version, OS, languages, time zone, storage APIs, and display metrics.
• Open Advanced Details to view user agent strings, UA-CH data, media capabilities, WebGL vendor/renderer (text), permissions snapshot, and network info.
• Compare fields marked Changed since last run to diagnose configuration updates or policy changes.
• Copy any row values for bug reports or support tickets.

Apply the detection results to speed up troubleshooting, standardize QA, and improve compatibility planning.

• Share an exact environment snapshot with support to reproduce browser-specific bugs.
• Verify storage APIs, cookies, and service worker availability before enabling PWA features.
• Confirm display metrics (viewport, DPR, color depth) for responsive and high-DPI testing.
• Check language, time zone, and reduced-motion preferences for localization and accessibility audits.
• Compare runs across devices or after updates to detect version changes or policy shifts that affect behavior.
• Capture WebGL vendor/renderer identifiers to investigate graphics or driver-related rendering issues.

Identify your exact browser, version, operating system, and device capabilities. Use this browser detector to run a fast, client-side check that reports user agent data, User-Agent Client Hints, screen resolution, color depth, touch support, storage APIs, and service worker support. Share accurate environment details with support teams, validate QA test plans, and confirm compatibility for progressive web apps and responsive design.

Run detection to capture a timestamped snapshot that you can compare across sessions. Confirm whether cookies, localStorage, sessionStorage, and IndexedDB are available. Verify accessibility preferences such as prefers-reduced-motion and prefers-color-scheme. Check WebGL vendor and renderer to investigate graphics issues on specific GPUs or drivers.

Speed up troubleshooting by copying relevant fields into bug reports. Reduce back-and-forth with support by providing the browser name, full version, platform, and display metrics in one place. Improve compatibility planning by checking language settings, time zone, device pixel ratio, and max touch points before shipping new features.

Reproduce a bug: Run detection, copy the browser name, version, OS, languages, and DPR, then attach the results to your ticket so QA can match your environment. Verify PWA readiness: Check cookies, service worker support, and storage APIs before enabling offline features. Tune responsive layouts: Confirm viewport size, orientation, and device pixel ratio on phones, tablets, and laptops to validate breakpoints and image density. Audit accessibility: Check reduced-motion and color-scheme preferences to ensure animations and themes respect user settings. Diagnose graphics issues: Use the WebGL vendor and renderer to identify problematic GPU and driver combinations that cause rendering artifacts.

What is my browser? Your browser is the software you use to access the web, such as Google Chrome, Mozilla Firefox, Microsoft Edge, Apple Safari, or Opera. This tool detects the browser name and exact version and shows related platform information so you can share precise details with support or QA.

How accurate is the detection? The tool combines the classic user agent string with User-Agent Client Hints when available. Modern privacy features may limit some fields, but the reported name, version, and platform are typically reliable for compatibility checks and debugging.

Does this tool store my data? The tool saves a snapshot locally in your browser using localStorage so you can compare runs. It does not transmit your results to a server. Clear your browser storage to remove saved snapshots.
