Nyx VPN: Encrypted. Private. Free. When other VPNs get blocked, Nyx keeps you connected. Built on next-generation stealth technology (V2Ray/Reality), Nyx gives you private, censorship-resistant access to the open internet with no account and no logs. WHY NYX • No sign-up, no email. Your identity is a single anonymous account number nothing ties the app to you. • Stealth that beats blocks. On-device detection spots when your network is being filtered (DPI, DNS or TLS interference) and automatically switches to Reality-grade stealth so you stay connected. • One app, every protocol. WireGuard, Hysteria2, VLESS, VMess, Trojan and Shadowsocks the right protocol for every network. • Strict no-logs. We don't keep records of the sites you visit or what you do online. • Strong encryption everywhere. Modern, military-grade encryption protects every connection especially on public Wi-Fi in hotels, cafes and airports. ONE TAP TO FREEDOM Open the app and tap once. Auto-connect and auto-reconnect keep you protected as you move between networks. A clean, fast interface in 18 languages, with light and dark mode. MORE THAN A VPN Nyx also includes a built-in private browser plus handy tools: speed test, ping, IP info and a secure password generator.

Verdict
The clearest difference is in-app purchases: O3Z at none against Nyx VPN's 3. O3Z also leads on iOS requirement (13.0 vs 16.0). Nyx VPN's advantage is update cadence (every 4 weeks vs every 4 months). On price, ads and device support there is nothing between them.
