What is Browser?
This tool detects and displays the web browser you are currently using — its name and version — along with your operating system, device type, rendering engine, language and screen resolution. Everything is read in your own browser using JavaScript; nothing is sent anywhere or stored.
How Browser works
Your browser exposes details through the navigator object and its user-agent string. This page parses that information to recognise common browsers such as Chrome, Firefox, Safari, Edge and Opera, and to work out your OS and device type.
Example: a user-agent containing Chrome/120 on Windows NT 10.0 is shown as “Chrome 120 on Windows 10/11, Desktop”.
Common uses
- Check which browser and version you are using
- Confirm your operating system and device type
- Provide accurate details in bug reports
- Verify you meet a site's browser requirements
Frequently asked questions
What browser am I using?
It is shown at the top of this page, along with the version number, detected from your browser.
How do I find my browser version?
See the Version row — this tool reads it automatically; no need to dig through menus.
Is this information private?
Yes. Detection happens entirely in your browser. We do not collect or store any of it.
Why does it say a different OS version?
Browsers sometimes report a simplified or frozen OS string for privacy, so the version may be approximate.
