What's My Browser? User Agent & Device Checker

The main result identifies the browser name and the most specific version that the browser exposes. It also shows the operating system, device type and full user agent string.

It checks browser-exposed values such as the user agent, browser brands, operating system, device category, screen and viewport, language, time zone, privacy preferences, hardware estimates, connection hints and supported web features.

A web browser is the application that retrieves and displays websites, such as Chrome, Edge, Firefox, Safari, Opera or Samsung Internet. A device brand such as HP, Dell, Apple or Samsung is not itself a browser.

Read the Browser Version value in the summary. The exact version can be reduced, frozen or omitted by privacy settings, browser policy, an embedded webview or user-agent spoofing.

A user agent string is text exposed by the browser that commonly contains product, platform and compatibility tokens. Websites can read it, but it is not a guaranteed or complete hardware identity.

Use Copy User Agent in the browser summary. When automatic clipboard access is blocked, select the displayed string manually or download the text report.

Yes. Paste a user agent into the User Agent Analyzer and select Analyze User Agent. The parser returns a best-effort browser, version, operating system, device type, engine and architecture.

No. User agents can be reduced, changed, spoofed, frozen or shared by several Chromium-based browsers. Use the result for support and diagnostics, not as proof of identity or security.

Many modern browsers include historical compatibility tokens such as Mozilla even when they are not Firefox. The parser evaluates more specific tokens before generic compatibility text.

Chromium-based browsers include compatibility tokens inherited from the web platform ecosystem. Correct parsing depends on checking the browser-specific Edge token before Chrome and Safari tokens.

Some browsers expose a distinct token or browser-specific interface, while others intentionally resemble Chrome. When no reliable distinct signal is exposed, the result may identify the underlying Chromium family instead.

Client hints are structured browser and platform values that may provide brands, mobile status, platform, architecture, bitness, model and full versions. Availability varies by browser, secure context and permissions policy.

The browser may not implement client hints, the page may not be in a secure context, privacy protections may reduce the values, or a permissions policy may restrict high-entropy hints.

Normally no visible permission prompt is shown, but the browser and site policy decide which values are returned. The button makes the optional request transparent and user initiated.

A reduced user agent commonly reports both as Windows NT 10.0, so the basic result may say Windows 10 or 11. Advanced platform-version hints can provide more detail when available, but should still be treated as browser-reported data.

Only when the browser exposes a model token or an advanced model hint. Many browsers intentionally omit or reduce exact model information for privacy.

The tool combines mobile client hints, user-agent patterns and touch information to infer desktop, mobile, tablet, webview or automated client. The device label is an estimate, not hardware certification.

The rendering engine is the browser component family that interprets web content. Common families include Blink, WebKit and Gecko, but browser branding and engine identity are separate concepts.

Screen size is the browser-reported display area in CSS pixels. Viewport size is the current webpage area and changes when the window, browser chrome, zoom or device orientation changes.

Device pixel ratio is the browser-reported ratio between device pixels and CSS pixels. It does not by itself reveal the physical screen size or guarantee a specific display density.

No page-specific request is made for an IP lookup or geolocation. The tool reports only values available locally in the browser page and does not request location permission.

Yes. The running page confirms JavaScript and reports the browser cookie-enabled setting. It also safely checks local and session storage without retaining the test values.

The feature panel checks availability of capabilities such as local storage, IndexedDB, service workers, web workers, WebAssembly, WebSocket, WebRTC, WebGL, WebGPU, clipboard, sharing, media devices and fullscreen.

No. A feature can exist but still require HTTPS, user activation, a permission, compatible hardware, browser policy or a supported file format. The panel reports interface availability only.

They are browser-exposed preference signals. A site or organization may interpret them differently, and their presence does not guarantee that every website changes its behavior.

Hardware concurrency and device memory are optional, privacy-sensitive estimates. Browsers may cap, round, reduce or omit them, especially outside Chromium-based desktop environments.

Connection information is optional and can be unavailable, rounded or based on a browser estimate. It is not a live bandwidth test and should not be treated as a measured internet speed.

Yes. Privacy modes, anti-fingerprinting settings, user-agent overrides, extensions, remote browsers and embedded apps can reduce or alter browser-exposed values.

Yes. Copy the concise support snapshot or download TXT or JSON. Review the report before sharing because it can include browser, platform, language, screen and capability details.

The page-specific checker processes the values in the current browser and does not send the generated report to an external service. Downloads are created locally, and the tool adds no page-specific permanent storage.

No account, extension, file upload, camera, microphone or location permission is required. Optional advanced client hints are requested only after you select the dedicated button.

Current Chrome, Edge, Firefox and Safari versions can show the standard browser snapshot. Advanced client hints and individual feature results vary by browser, platform and security context.
