# VLess **VLess is a lightweight and efficient VPN protocol designed for enhanced security and performance.** It's a newer protocol that builds upon the foundation of VMess, another popular VPN protocol. VLESS offers several advantages over VMess, making it a more attractive option for many users. It’s the best choice for users who need to circumvent blocks. VLess is designed with the need to obscure internet traffic, making it less detectable by censorship filters, but this can result in slower connection speeds compared to WireGuard. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
