How Browser Detection Works

Brave Detection

Brave is the only browser that exposes a navigator.brave object with an isBrave() method. This is the most reliable way to detect Brave, as it's an intentional API provided by Brave Software.

if (navigator.brave && await navigator.brave.isBrave()) {
  // User is on Brave Browser
}

Chrome vs Chromium-based Browsers

Many browsers (Edge, Opera, Brave) are built on Chromium and include "Chrome" in their User Agent string. To identify true Chrome, we check for the absence of other browser identifiers (Edg, OPR, Brave) while confirming the presence of "Chrome".

const ua = navigator.userAgent;
const isChromium = ua.includes('Chrome');
const isEdge = ua.includes('Edg');
const isOpera = ua.includes('OPR');
// True Chrome = Chromium without Edge/Opera/Brave markers

Firefox Detection

Firefox uses the Gecko engine and identifies itself clearly in the User Agent with "Firefox". It's straightforward to detect as no other major browser uses this identifier.

const isFirefox = ua.includes('Firefox');

Safari Detection

Safari detection is tricky because Chrome's UA also contains "Safari". We detect Safari by checking for "Safari" in the UA while excluding Chrome and Chromium identifiers. Safari is the only major browser using WebKit without also being Chromium-based.

const isSafari = ua.includes('Safari') &&
                 !ua.includes('Chrome') &&
                 !ua.includes('Chromium');

Limitations & Privacy

User Agent strings can be spoofed, and privacy-focused browsers may modify or reduce fingerprinting signals. This tool uses client-side detection only and does not send any data to external servers. For the most accurate Brave detection, the navigator.brave API is authoritative since it requires Brave's actual codebase to expose it.
