    I’d use the navigator.userAgent property, but this can be easily edited by the user to appear as something else.

    function isUserOnTelegram(){
    return navigator.userAgent.includes('Telegram');
}

    Joshua’s answer can work but it is not recommended since the user can easily bypass it.

    The best way is to check if web sockets are available, sin some features are not available on telegram web app.

    This is the code for it:

    const supportsWebRTC = !!window.RTCPeerConnection;
if (supportsWebRTC) {
  // Likely a regular browser
} else {
  // May be Telegram web app
}
