Why search for the flag when I can make a bookmarklet to print it for me? Browse here, and find the flag!

Steps :

site have a js code :

        javascript:(function() {
            var encryptedFlag = "àÒÆަȬë٣֖ÓÚåÛÑ¢ÕӗԚÅКٖí";
            var key = "picoctf";
            var decryptedFlag = "";
            for (var i = 0; i < encryptedFlag.length; i++) {
                decryptedFlag += String.fromCharCode((encryptedFlag.charCodeAt(i) - key.charCodeAt(i % key.length) + 256) % 256);
            }
            alert(decryptedFlag);
        })();
    

lets run this and get the output:

RUN 
 javascript:(function() {
            var encryptedFlag = "àÒÆަȬë٣֖ÓÚåÛÑ¢ÕӗԚÅКٖí";
            var key = "picoctf";
            var decryptedFlag = "";
            for (var i = 0; i < encryptedFlag.length; i++) {
                decryptedFlag += String.fromCharCode((encryptedFlag.charCodeAt(i) - key.charCodeAt(i % key.length) + 256) % 256);
            }
            alert(decryptedFlag);
        })();
 
picoCTF{p@g3_turn3r_1d1ba7e0}
