WebSocket connections are opened directly by this browser and can target ws/wss services on other domains. The target server may still reject connections based on Origin, authentication or protocol rules. Browser pages cannot set arbitrary request headers. Use this tool only for services you are authorized to test; it does not provide scanning, brute-force or access-control bypass features.
