What Is a Browser Checker?
A browser checker is an online tool that reads information exposed by your browser through standard JavaScript APIs — including your browser name and version, operating system, screen resolution, GPU, timezone, connection type and dozens of capability flags. This tool detects over 60 data points instantly, all client-side, with no server involved and no privacy risk.
Frequently Asked Questions
What browser am I using right now?
Your browser is detected automatically the moment you open this page. The tool reads your user agent string and identifies the browser name, version and rendering engine.
Common browsers detected include Google Chrome, Mozilla Firefox, Apple Safari, Microsoft Edge, Opera and Brave.
The detected browser name and version appear at the top of the results in the Browser and Operating System section.
What system information can I check with this tool?
This browser info checker detects over 60 data points: browser name and version, rendering engine, OS, device type, screen resolution, viewport, device pixel ratio, color depth, physical resolution, GPU vendor and renderer, WebGL version, GLSL version, audio sample rate and latency, camera and microphone count, CPU cores, device memory, battery status, connection type, download speed, RTT latency, timezone, language, privacy signals and storage quota.
The capabilities section checks 30+ browser features including WebGL, WebGL2, WebAssembly, Service Workers, WebRTC, Web Bluetooth, WebUSB, WebXR, Payment Request API, SubtleCrypto, SharedArrayBuffer, Screen Capture, File System Access and more.
Media codec support is also shown: H.264, WebM/VP8, AV1, HLS, MP3, AAC, OGG, Opus and FLAC.
Is this browser checker completely private?
Yes. All detection happens entirely in your browser using standard JavaScript APIs. No data is ever sent to our servers.
The tool does not collect, log or store your browser data, IP address, user agent or any other information.
You can verify this by opening browser developer tools — there are no network requests made after the initial page load.
How do I find my browser version?
Your browser version is shown automatically in the Browser and Operating System section. No action needed — it is detected the moment you open the page.
You can also check manually: in Chrome go to Menu > Help > About Google Chrome. In Firefox go to Menu > Help > About Firefox. In Safari go to Safari > About Safari.
Keeping your browser up to date is important for security, performance and access to the latest web features.
What is a user agent string and how do I copy mine?
A user agent string is a line of text your browser sends automatically to every website you visit. It identifies your browser, version, operating system and rendering engine.
Websites use user agent strings to detect your browser type and serve compatible content. Developers use them to debug browser-specific issues.
This tool displays your full user agent string at the bottom of the page with a one-click Copy button.
What does GPU vendor and renderer mean?
The GPU vendor is the manufacturer of your graphics card such as NVIDIA, AMD, Intel or Apple. The renderer is the specific GPU model or driver used for web rendering.
This information is exposed through the WebGL API using the WEBGL_debug_renderer_info extension. It is used by developers to test and optimize graphics-heavy web applications.
Some browsers or privacy configurations may mask GPU details. In those cases the tool displays the generic WebGL renderer string instead.
Can I check if my browser supports WebGL, WebAssembly or Service Workers?
Yes. The Browser Capabilities section lists 30+ modern web APIs with a clear Yes or No for your current browser, including WebAssembly, WebGL, WebGL2, Service Workers, Web Workers, WebRTC, Web Bluetooth, WebUSB, WebXR, Notifications, Geolocation, Clipboard API, Payment Request and more.
Each feature shows a green Yes or red No status based on your current browser and device configuration.
This is useful for developers debugging browser compatibility issues or for users checking if their browser meets the requirements of a specific application.
Does this tool detect if I am using an automated browser or bot?
Yes. The Privacy and Tracking section includes a WebDriver detection check. The navigator.webdriver property is set to true when a browser is controlled by automation tools like Selenium, Puppeteer or Playwright.
Websites use this signal to detect automated browsers and testing environments.
If you are a regular user browsing normally, the tool will show Not Detected for WebDriver.
