VLESS vs WireGuard: Which Protocol Should You Use
WireGuard is excellent for speed and simplicity on home networks and in countries without heavy VPN blocking. VLESS + Reality is significantly better in hotels, airports, schools and countries with active VPN filtering — because it resembles HTTPS and evades deep packet inspection. Outlivion defaults to VLESS + Reality for this reason.
WireGuard: fast and simple
WireGuard is a modern protocol with excellent throughput, low latency and a small codebase. It is well-audited and supported natively on Linux and increasingly on other platforms.
Its limitation: WireGuard has a distinctive UDP fingerprint on port 51820. Firewalls and ISPs can identify and block it with a simple DPI rule.
VLESS + Reality: designed for blocked environments
VLESS is a lightweight protocol from the Xray project. Reality is a TLS masquerade layer that makes traffic look like HTTPS to a real website.
The result: VPN traffic that passes through most corporate firewalls, hotel networks and country-level censorship systems unchanged.
Speed comparison
WireGuard has slightly lower latency and higher raw throughput on unrestricted networks. The difference is negligible for browsing, calls and HD streaming.
In practice, VLESS + Reality is often faster in restricted environments because it does not need to retry failed connections or fall back to alternative ports.
When to use each
WireGuard: home network or in a country with no VPN filtering where you prioritise maximum throughput.
VLESS + Reality: travel, hotel Wi-Fi, school networks, UAE, China, Iran, or any network that actively filters VPN traffic.
- WireGuard: home, unrestricted countries, maximum throughput
- VLESS + Reality: travel, restricted networks, censored regions
What Outlivion uses
Outlivion defaults to VLESS + Reality because most of our users connect from hotel, airport and travel networks. This ensures reliable access in the scenarios that matter most.

Frequently asked questions
Contact support — server capabilities vary by plan and region. VLESS + Reality is the default for all plans.
Both are secure. WireGuard has a smaller attack surface due to its minimal codebase. VLESS + Reality's security model is different — TLS + Reality extension. Neither has known critical vulnerabilities.
WireGuard is slightly more efficient on battery due to lower cryptographic overhead. The difference is small in normal use.
Yes. The Happ client on iOS supports VLESS + Reality.
