Ultimate 1-Minute Xray/3x-ui Setup: VLESS, Hysteria2, Caddy Self-Steal & Smart Outbounds in One Script

An open-source bash script, 3xui-fast-install, automates deploying a hardened Xray node with a 3x-ui panel.

It supports multiple transports including VLESS, Reality, and Hysteria2, with TLS termination via Caddy or Let’s Encrypt.

The script also bundles security and performance setup such as UFW, Fail2ban, BBR, Docker, and custom routing rules.

It can route outbound traffic through tools like Cloudflare WARP, Opera Proxy, or Tor, reducing manual setup on Ubuntu and Debian VPSs.
