How to Set Up 3X-UI VPN on Your VPS — Step-by-Step Guide

// 1. What Is 3X-UI VPN?

3X-UI is a free, open-source graphical user interface for managing VPN servers, built on top of the Xray-core project. It gives you a full web-based admin panel to manage users, protocols, traffic, and SSL certificates — all from your browser.

Supported protocols:

• VMess — Classic V2Ray protocol with encryption and obfuscation
• VLESS with REALITY — Next-generation protocol for maximum security and anti-detection
• ShadowSocks — Lightweight encrypted proxy protocol
• WireGuard — Modern, high-performance VPN protocol
• Trojan — Disguises VPN traffic as normal HTTPS connections

Built-in features include user management, traffic monitoring, bandwidth limits, expiration dates, and automatic SSL via Let's Encrypt.

Who it's for:

• Privacy-conscious users who want full control over their VPN
• Developers and system administrators managing remote access
• Small VPN providers serving clients or teams
• Remote workers needing secure connections to company resources
• Gamers looking to reduce latency with custom routing

// 2. Why Self-Host Your VPN?

Commercial VPN services are convenient, but they come with tradeoffs. Self-hosting with 3X-UI eliminates most of them:

• No logging by third parties — You control all data. No one else sees your traffic or keeps logs.
• No bandwidth limits — Commercial VPNs throttle speeds. Your VPS gives you the full pipe.
• Choose your server location — Pick from 12 global locations for the lowest latency to your needs.
• Multi-user support — Share your VPN with family or team members, each with their own credentials and limits.
• Much cheaper long-term — A $24.99/mo VPS replaces multiple commercial VPN subscriptions.
• Complete protocol flexibility — Choose the best protocol for your situation, including advanced options like VLESS+REALITY for bypassing restrictions.

// 3. VPS Requirements

3X-UI itself is lightweight, but bandwidth and concurrent connections scale with your hardware. For a personal VPN serving 1-3 users, VPS Start ($24.99/mo) is all you need. For multi-user deployments, step up to VPS Medium ($39.99/mo) for unmetered bandwidth and more headroom.

// 4. Step-by-Step: Install 3X-UI on DejavuHost

Prefer to install it yourself? Choose Ubuntu 22.04 LTS or Debian 12, then follow the steps below.

• Head to our VPS Hosting page and select VPS Start or VPS Medium
• Pick a server location closest to where you'll use the VPN
• Complete checkout (we accept Bitcoin via BTCPay!)

Once your VPS is provisioned (typically within a few hours), you'll receive your server credentials via email.

Run the official 3X-UI installer:

The installer will ask you to:

1. Set a custom admin username and password
2. Choose a panel port (use a non-standard port for security)
3. Set a web base path (e.g., /secretpath)

Open your browser and navigate to your panel:

Log in with the credentials you set during installation. You'll see the 3X-UI dashboard with system stats, connection status, and the inbound management panel.

Set up your first inbound connection:

1. Go to Inbounds and click Add Inbound
2. Set a descriptive name for your connection
3. Select protocol: VLESS (recommended with REALITY for best security)
4. Configure REALITY settings: uTLS fingerprint, destination domain, generate keys
5. Add a client with an identifier email
6. For REALITY: set Flow to "xtls-rprx-vision"
7. Save and copy the connection URL

Use the connection URL or QR code from Step 5 with one of these clients:

// 5. Pre-Installation & Custom Setup

Unlike other providers that hand you a blank server, DejavuHost offers application pre-installation at no extra cost. Whether it's 3X-UI, OpenVPN, WireGuard standalone, or any other VPN solution — tell us what you need and we'll set it up.

Here's how it works:

1. Select "Other (Raise a Ticket)" from the OS dropdown during checkout
2. In your ticket, mention the application you want pre-installed (e.g., "3X-UI VPN panel on Ubuntu 22.04")
3. Complete your order as normal
4. Our team provisions your VPS with 3X-UI installed, SSL configured, and ready to add clients
5. You receive your panel login credentials and get started immediately

This applies to 3X-UI and any other application you need. No extra cost, no hassle — your server arrives ready to use.

// 6. Troubleshooting

// 7. Wrap-Up

3X-UI gives you a full-featured VPN management panel for free — multi-protocol support, user management, traffic monitoring, and SSL automation, all through an intuitive web interface.

Our VPS Start plan ($24.99/mo) is all you need for a personal VPN serving 1-3 users. Scale up to VPS Medium ($39.99/mo) for multi-user deployments with unmetered bandwidth, or VPS Premium ($64.99/mo) if you're running a small VPN provider.

Or skip setup entirely — we'll pre-install 3X-UI and have it ready for you to add clients the moment you log in.
