What Is My Browser?
Full device snapshot in 7 sections — browser & engine, OS, display (resolution, viewport, pixel ratio, color depth), hardware (CPU cores, memory, touch), locale & time zone, preferences (color scheme, reduced motion, DNT), state (cookies, automation), and capabilities (WebGL, WebGPU, service worker, geolocation, storage).
Detecting…
All info is detected locally via window.navigator, window.screen and matchMedia. Nothing is uploaded.
How to use this what is my browser
- Open this page in the browser you want to inspect — detection runs automatically on load.
- Browse the seven sections: browser & engine, OS, display, hardware, locale, preferences, capabilities. Each value reflects what your browser actually exposes — not a guess.
- Tap any field to copy just that value. Useful when filing a bug report and the developer asks for one specific detail.
- Click 'Copy all info' for a complete text dump — paste it into bug reports or support tickets so the developer doesn't have to ask follow-up questions.
- Refresh the page after changing browser settings (dark mode, language, do-not-track) to see updated values — none of this is cached.
Frequently asked questions
How accurate is browser detection?
We use the modern userAgentData API when available (correctly identifies Brave, Vivaldi, Edge etc.) and fall back to user-agent string parsing otherwise. The UA string is decades old and easily spoofed, but for genuine browsers it's still the most reliable identifier — fingerprint-evasion extensions can lie about it, in which case the result reflects what they're claiming, not the real browser.
What is WebGL renderer?
The GPU model your browser exposes for hardware-accelerated graphics. Useful for diagnosing rendering issues — if WebGL shows 'SwiftShader' or 'Mesa software', your browser fell back to CPU rendering (slow, but works on machines without GPU drivers). Native GPU names like 'NVIDIA GeForce RTX 4070' or 'Apple M2 Pro' mean hardware acceleration is on.
What does 'storage estimate' mean?
How much disk this site (or any origin) can use, and how much is currently used. Reflects browser-allocated quotas — usually 50-60% of free disk on Chrome, less on Safari. Big web apps (offline maps, video editors) need to check this before saving — going over the quota triggers a quota-exceeded error.
Why does my user-agent show 'Chrome' when I'm using Brave or Edge?
Chromium-based browsers share Chrome's user-agent string by default to dodge sites that gate features by browser. The modern userAgentData API exposes the real brand (Brave, Edge, Vivaldi) — that's what's shown when supported, with UA fallback otherwise. Safari ironically still announces itself accurately; Chromium derivatives intentionally don't.
Can I trust this info for fingerprinting or anti-fraud testing?
Partially. The values here show what a server-side fingerprint would also see — but real fingerprinting systems combine these signals with timing, canvas hash, audio context and dozens of other inputs to produce a unique identifier. Use this tool to verify what your browser exposes; don't assume matching values means a real fraud system would identify you the same way.
