Browser Info
See exactly what your web browser reveals about you — version, operating system, language, screen, cookies and which modern features it supports. Everything is detected locally and never sent anywhere.

How to use the Browser Info tool
- Scan the summary. The top cards name your browser, operating system and device type, parsed from the user agent string shown below them.
- Review the details. The details table lists language, timezone, CPU cores, memory, screen and more, while the features table shows which modern web APIs your browser supports.
- Export the report. Copy the full report or download it as a text file to attach to a bug report or share with a developer.
About this tool
Every time you open a website, your browser hands over a surprising amount of information: its name and version, your operating system, preferred languages, timezone, screen resolution, and whether features like WebGL, service workers or the clipboard API are available. This browser info tool gathers all of that in one place so you can see your own digital fingerprint the way a website would. It is useful for debugging site problems, checking feature support before using a new API, or simply understanding what data your browser exposes.
All detection runs with plain JavaScript inside your browser using the standard navigator, screen and feature-detection APIs. Nothing is transmitted to a server, logged or tracked — the report exists only on your screen until you copy or download it. That makes this a safe, private way to inspect your browser configuration without any third-party analytics involved.
Frequently asked questions
Does this tool track me or store my information?
No. All values are read locally in your browser and displayed only to you. Nothing is uploaded, saved on a server or shared with any third party. If you close the tab, the report is gone.
Why does my browser version look wrong or generic?
Modern browsers deliberately "freeze" or reduce parts of the user agent string to limit fingerprinting. Chromium browsers, for example, cap the version details and mask the exact OS build. The tool shows the best interpretation of what your browser reports.
What does "device type" mean and how is it detected?
Device type is a best-guess of desktop, tablet or mobile based on keywords in your user agent and touch capabilities. Because any device can spoof its user agent, treat it as a strong hint rather than a guaranteed fact.
Why do some features show as not supported?
A feature shows as unsupported when your browser lacks the relevant API, or when a security setting (such as blocking third-party storage) disables it. Some APIs also require a secure HTTPS context, so results can differ between sites.
