VLESS Protocol
VLESS Protocol
Lightweight and efficient VPN protocol optimized for streaming and high-bandwidth activities with minimal overhead.
VLESS is OrbVPN's stealth workhorse
By default, VLESS runs over the Reality transport (XTLS-Vision), which performs a genuine TLS handshake with a real website's certificate — making your traffic cryptographically indistinguishable from normal HTTPS. VLESS also supports Direct TCP, WebSocket, gRPC, and Cloudflare CDN Fronting transports, and pairs with OrbVPN's 10 mimicry profiles. Learn more in the Reality transport guide.
