    Description

    About Browser Information

    Introduction

    Browser Information focuses on the software side of your session: engine and platform clues, user-agent context, and a compact feature matrix. Use it when the question is “which browser and what can it do,” not “what size is my screen.”

    What this tool does

    It summarizes identity and capability signals the browser exposes to pages, with clear empty states when privacy reduction hides detail. Hardware-heavy fields such as concurrency, memory, and viewport depth live on Device Information instead, with short pointers here when useful.

    When to use it

    Use it for support macros, WebView checks, and feature planning. Prefer User Agent when a CDN or legacy sniffer is the dispute, Browser Features for a wider API matrix, and Device Information for geometry and hardware hints.

    How it works

    Reads navigator and related surfaces in-page. Client Hints and reduced user agents intentionally omit older detail. Feature rows are detection checks, not guarantees that permissioned APIs will succeed after a prompt.

    Step-by-step instructions

    1. Open Browser Information over HTTPS in the profile under test.
    2. Note engine, platform, and any reduced or incomplete identity fields.
    3. Scan the feature summary for APIs relevant to your bug.
    4. Cross-check Device Information or User Agent when the ticket needs those angles.

    Common problems

    Incomplete fields are often privacy policy, not a broken page. In-app WebViews differ from desktop Chrome. Extensions that spoof the user agent change what you see here.

    Privacy explanation

    Identity and feature signals stay in your tab for diagnostics. DeviceHub does not sell fingerprint marketplace data from this page.

    Runtime principles

    Built for the browser

    What happens when you run this test — without downloads or accounts.

    1. 01

      Runs in your browser

      Browser Information uses standard web APIs — no install, extension, or desktop app required.

    2. 02

      Reads what the browser allows

      Results come from events and capability signals the web platform exposes for this session.

    3. 03

      Private by default

      Input and diagnostic values stay in your browser session for display — nothing is sold as media.

    Compatibility

    Supported browsers

    Expected support for modern engines. Individual APIs may still vary by device.

    Hardware and form factors this browser test is designed to exercise.

    • Desktop browsers

      Chrome, Firefox, Safari, and Edge on Windows, macOS, Linux.

    • Laptops

      Reports identity and feature signals for the active session.

    • Phones & tablets

      Mobile browsers with web platform capability probes.

    Privacy

    Your data stays with you

    Browser Information is built privacy-first. Diagnostics run in your browser session whenever web APIs allow.

    Troubleshooting

    Common problems

    Quick fixes before you dig into FAQs.

    Values look incomplete or generic
    User-agent reduction and Client Hints intentionally limit detail. Compare User Agent and Browser Features tools, and try another browser if you need a second view.
    Feature matrix disagrees with documentation
    Enterprise policies, private mode, and feature flags can disable APIs that docs list as supported. Retest in a clean profile and check Browser Features for a focused probe list.
    Mobile reports a desktop-like platform
    Request Desktop Site and some WebViews rewrite platform hints. Capture Browser Info from the same profile where the bug occurs.

    Browse FAQs
    What does Browser Information show?
    Engine and platform context, user-agent related signals, and a compact feature summary for the current session.
    Why do some fields look incomplete?
    User-agent reduction and Client Hints intentionally limit detail for privacy.
    Is this the same as Device Information?
    No. Device Information covers viewport and hardware-oriented signals. This page stays on browser software and features.
    Does it change my settings?
    No. It only reads what the browser already exposes to web pages.
    Is data stored for ads?
    DeviceHub shows diagnostic fields in your session. It is not a fingerprint marketplace.
