3X-UI — advanced, open-source web-based control panel designed for managing Xray-core server. It offers a user-friendly interface for configuring and monitoring various VPN and proxy protocols.

Important

This project is only for personal usage, please do not use it for illegal purposes, and please do not use it in a production environment.

As an enhanced fork of the original X-UI project, 3X-UI provides improved stability, broader protocol support, and additional features.

Quick Start

bash <(curl -Ls https://raw.githubusercontent.com/mhsanaei/3x-ui/master/install.sh)

Database Backends

3X-UI supports both SQLite and PostgreSQL as interchangeable backends. All application logic is written against GORM — Go's database-agnostic ORM — so queries work identically on either engine. You can switch backends at any time through the panel UI without data loss.

Choosing a Backend

	SQLite	PostgreSQL
Setup	Zero config, file-based	Requires a running PG server
Best for	Single-node, low traffic	Multi-node, high concurrency
Backups	Portable + native file export	Portable export

Switching Backends (Panel UI)

1. Open Settings → General → Database.
2. Select a backend (SQLite or PostgreSQL) and fill in connection details.
3. Click Test Connection to verify.
4. Click Switch Database — the panel will:
   • Save a portable backup of current data automatically.
   • Migrate all data to the new backend.
   • Restart itself.

The target database must be empty before switching. Use Test Connection before switching to catch misconfigurations early.

Local PostgreSQL (panel-managed)

When selecting Local (panel-managed) mode, the panel installs and manages PostgreSQL automatically (Linux, root only):

# The panel uses postgres-manager.sh internally.
# No manual PostgreSQL setup required.

External PostgreSQL

Point the panel at any existing PostgreSQL 13+ server:

1. Create a dedicated database and user.
2. Enter the connection details in Settings → Database.
3. Use Test Connection, then Switch Database.

Environment Variable Override

For Docker and infrastructure-as-code deployments, set these environment variables to control the backend without touching the UI:

XUI_DB_DRIVER=postgres        # or: sqlite
XUI_DB_HOST=127.0.0.1
XUI_DB_PORT=5432
XUI_DB_NAME=x-ui
XUI_DB_USER=x-ui
XUI_DB_PASSWORD=change-me
XUI_DB_SSLMODE=disable        # or: require, verify-ca, verify-full
XUI_DB_MODE=external          # or: local
XUI_DB_PATH=/etc/x-ui/db/x-ui.db   # SQLite only

When any XUI_DB_* variable is set, the Database section in the panel UI becomes read-only.

Backup & Restore

Format	Works with	When to use
Portable (.xui-backup)	SQLite + PostgreSQL	Switching backends, Telegram bot backups, long-term storage
Native SQLite (.db)	SQLite only	Quick raw file backup while on SQLite

• The Telegram bot sends a portable backup automatically — this works regardless of which backend is active.
• Portable backups can be imported back on either SQLite or PostgreSQL.
• Legacy .db files from older 3x-ui versions can be imported even while PostgreSQL is active.
