5 Best Browser Engine Detection Tools Reviewed:

1. ToDetect

ToDetect’s browser engine version detection can directly read the browser’s exposed core version and cross-check UA, Client Hints, and other data. It helps uncover browser spoofing, UA mismatches, and other issues. Both regular users and technical users can rely on it.

Opening the page instantly identifies your environment—no actions required. ToDetect supports browsers across various environments such as Chrome, Edge, Safari, Firefox, and Chinese multi-kernel browsers like 360, QQ, and Sogou. Whether on desktop, Android WebView, or more complex multi-kernel setups, it reliably outputs the actual engine version so you can quickly confirm your real runtime environment.

2. WhatIsMyBrowser

WhatIsMyBrowser is a long-standing browser detection website where you can check UA details and basic environment information.

It breaks down browser information into understandable modules, making it easy for users to interpret results and identify potential compatibility issues.

3. UserAgentString.com

A website focused on User-Agent analysis, mainly listing browser and system information extracted from UA strings.

With its massive UA database, it can accurately identify UA origins and versions. It remains a classic tool for handling UA anomalies.

4. Device Info

Device Info detects browsers based on real behavior—rendering characteristics, screen data, architecture abilities, JS engine performance, and more. Since these traits are hard to fake, it offers high-value insights for identifying virtual environments and verifying device authenticity.

5. Chrome://version (Built-in)

Chrome and Edge include a built-in chrome://version page.

You can view complete Chromium build versions, command-line flags, paths, and profile information. This is the most authoritative and accurate way to confirm genuine Chrome or Edge (Chromium-based) versions. Open the page to see official, unaltered data.

• Note: This page works only for official Chromium-based browsers; it cannot determine whether UA strings are genuine and does not support iOS WebKit engines.
