Identify the browser, engine and platform

Web teams use it to identify a visitor’s browser, engine and platform during compatibility testing or log analysis.

Identify the browser, engine and platform. Everything runs in your browser, so the values you enter are never uploaded, shared, or stored.

How to use

Paste a User-Agent string into the input area.
Run the analysis to identify the browser, engine and platform.
Read the recognized details and note the ones relevant to your test.
Clear the field before checking another User-Agent string.

Example

The provided example is a common User-Agent string. After analyzing, look at the browser, engine and system detected. If some values remain unknown, the string may have been altered or may be too old.

Input

Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36

Limits and formats

User-Agent strings can be spoofed or modified, so results are only indicative.
An unknown or very specific string may produce partial information.
The tool does not test the real features of the browser or its compatibility.
Supported text files can be imported, but analyzing one string at a time is clearer.

Where processing happens

The analysis runs in your browser. The string you paste stays on your device and is not sent anywhere. You can inspect logs or test data without an account.

Frequently asked questions

Why does the result not match the browser I see?

A User-Agent string may be changed by an extension, a tool or a compatibility mode. The result reflects the text provided, not necessarily the software actually in use.

Can I analyze several strings at once?

The tool works with the string in the input area. For several visitors, paste each string separately so the results remain easy to compare.

Is this enough for a compatibility test?

No, it gives a clue about the browser, engine and platform. To confirm behavior, test the page in the browser you are investigating.

Can a User-Agent string be changed by an extension or tool?

Yes. User-Agent strings can be spoofed or modified, so results are only indicative. The analysis identifies the browser, engine and platform from the text provided, but an extension, tool or compatibility mode may change that text. Clear the field before checking another string. The analysis runs in your browser and the string stays on your device.

What details does the analysis try to identify?

It tries to identify the browser, engine and platform from the User-Agent string. Read the recognized details and note the ones relevant to your test. An unknown or very specific string may produce partial information. The tool does not test the real features of the browser or its compatibility. The string you paste stays on your device.
