User-Agent 문자열 모음 (PC·모바일·인앱 브라우저·검색봇)

User-Agent(UA)는 브라우저나 프로그램이 서버에 요청을 보낼 때 "나는 어떤 클라이언트다"라고 밝히는 헤더 값입니다. 개발하다 보면 이 문자열이 필요해지는 순간이 꽤 있습니다. VB.NET이나 VBA로 웹 페이지를 긁어올 때 기본 UA로 보내면 막히는 사이트가 있어서 실제 브라우저 값을 넣어야 하고, PHP로 접속 로그를 분석할 때는 들어온 요청이 PC인지 모바일인지, 사람인지 봇인지 구분해야 하죠. 아래는 실제 접속 기록에서 볼 수 있는 UA 문자열을 모아 둔 목록입니다.

문자열을 읽는 요령

거의 모든 UA가 Mozilla/5.0으로 시작하는데, 이건 역사적인 이유로 붙어 있는 관례일 뿐 Firefox라는 뜻이 아닙니다. 실제 정보는 괄호 안과 그 뒤에 있습니다.

괄호 안은 운영체제입니다. Windows NT 10.0은 윈도우 10(11도 이 값으로 보고하는 경우가 많습니다), 6.1은 윈도우 7, 6.2는 8, 6.3은 8.1, 5.1은 XP입니다. Win64; x64는 64비트 브라우저, WOW64는 64비트 윈도우에서 돌아가는 32비트 브라우저라는 뜻이고요. 모바일은 Android 9; SM-N950N처럼 안드로이드 버전과 기기 모델명이, 아이폰은 iPhone OS 12_3_1처럼 iOS 버전이 들어갑니다.

괄호 뒤쪽은 브라우저 엔진과 이름입니다. 여기서 헷갈리는 부분은 크롬 계열 브라우저들이 모두 Chrome/버전 Safari/537.36을 달고 다닌다는 점입니다. 그래서 브라우저를 판별할 때는 맨 뒤에 붙은 고유 토큰을 먼저 봐야 합니다. Whale/이면 네이버 웨일, OPR/이면 오페라, Edge/면 구버전(EdgeHTML) 엣지, SamsungBrowser/면 삼성 인터넷입니다. 이런 토큰이 없을 때 비로소 크롬으로 봅니다. Trident/7.0; rv:11.0은 인터넷 익스플로러 11입니다.

인앱 브라우저와 봇

목록에 섞인 KAKAOTALK, NAVER(inapp; ...)는 카카오톡이나 네이버 앱 안에서 링크를 열었을 때의 UA입니다. 안드로이드 쪽은 ; wv(WebView)가 함께 붙어 있죠. 인앱 브라우저는 파일 다운로드나 팝업, 외부 로그인 연동이 일반 브라우저와 다르게 동작하는 경우가 많아서, 이 토큰을 보고 "외부 브라우저로 열어 주세요" 안내를 띄우는 처리를 종종 합니다.

Googlebot, Google Favicon, BingPreview, PhantomJS는 사람이 아니라 검색엔진 수집기나 자동화 도구입니다. 접속 통계를 낼 때 이런 요청을 빼지 않으면 방문자 수가 부풀려집니다. 다만 UA는 보내는 쪽이 마음대로 적을 수 있는 값이라, 정말 구글 봇인지 확인해야 할 때는 UA만 믿지 말고 접속 IP의 역방향 DNS까지 확인하는 게 정석입니다. 목록 중간의 Mozilla / 5.0(...)처럼 공백이 이상하게 들어간 값이나 앞에 숫자가 붙은 값은 손으로 만든 UA를 쓰는 크롤러일 가능성이 높습니다.

코드에서 쓰는 방법

VB.NET에서 요청을 보낼 때 UA를 지정하는 가장 간단한 방법입니다.

Using wc As New Net.WebClient()
    wc.Headers.Add("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/75.0.3770.142 Safari/537.36")
    Dim html As String = wc.DownloadString("https://example.com/")
End Using

PHP에서 들어온 요청의 UA는 $_SERVER['HTTP_USER_AGENT']로 읽습니다. 모바일 여부 정도는 간단한 정규식으로 충분합니다.

<?php
$ua = $_SERVER['HTTP_USER_AGENT'] ?? '';
$isMobile = preg_match('/Mobile|Android|iPhone|iPad/i', $ua) === 1;
$isKakao  = stripos($ua, 'KAKAOTALK') !== false;
$isBot    = preg_match('/bot|crawler|spider|BingPreview|PhantomJS/i', $ua) === 1;

크롤링 용도로 위 목록에서 UA를 고를 때는 너무 오래된 버전은 피하는 게 좋습니다. 목록에 있는 크롬 버전대는 지금 기준으로 한참 지난 값이라, 일부 사이트는 "지원하지 않는 브라우저" 페이지를 돌려주기도 합니다. 그런 응답이 오면 내 PC 브라우저의 현재 UA(주소창에 개발자 도구를 열고 navigator.userAgent를 입력하면 나옵니다)로 바꿔 보는 게 가장 빠른 해결책입니다. 그리고 최근 크롬은 UA에 들어가는 정보를 일부러 줄이고 있어서, 세밀한 기기 판별이 필요하다면 UA 문자열만으로는 한계가 있다는 점도 염두에 두세요.
