What is Discordbot?
Discordbot is Discord's web crawler that generates link embeds when URLs are shared in Discord servers and direct messages. With Discord's massive user base spanning gaming, education, and communities, the bot plays a crucial role in content discovery. It creates rich embeds with images, titles, and descriptions, making shared content more engaging. The bot supports Open Graph tags and provides special handling for media content like videos and images. For content creators targeting Discord's diverse communities, proper metadata ensures their content is attractively presented.

function detect_discordbot() {
$user_agent = $_SERVER['HTTP_USER_AGENT'] ?? '';
$pattern = '/Discordbot/i';
if (preg_match($pattern, $user_agent)) {
// Log the detection
error_log('Discordbot detected from IP: ' . $_SERVER['REMOTE_ADDR']);
// Set cache headers
header('Cache-Control: public, max-age=3600');
header('X-Robots-Tag: noarchive');
// Optional: Serve cached version
if (file_exists('cache/' . md5($_SERVER['REQUEST_URI']) . '.html')) {
