Frequently asked questions
How do I use What is my Browser?
1. Open the tool: There are no fields to fill in. The tool reads the details your browser sends with every request. 2. Run the check: Press Run What is my Browser to send a normal request to GigaTools. 3. Read your details: You see your browser and version, operating system and device type, followed by the full user agent string and the IP address the server received the request from.
Does it name my browser and version?
Yes. The tool reads the browser, its main version, the operating system and the device type from the user agent. Browsers freeze some details, so Windows 11 shows as Windows 10 or 11 and the macOS version is not revealed.
Why does my user agent mention several browsers?
For historical compatibility, most browsers include words like Mozilla, AppleWebKit or Safari, so the string can list names you are not actually using.
Why is the IP different from the one my router shows?
Your router shows a local network address. This tool shows the public address that reached GigaTools, which may belong to your provider, a VPN or a proxy.
Is this information stored?
The result is built from the request your browser already sends, and the result page is marked private and not cached. Like any website, the server may keep standard access logs.
