**3X-UI** is an advanced, open-source web control panel for managing [Xray-core](https://github.com/XTLS/Xray-core) servers. It provides a clean, multi-language interface for deploying, configuring, and monitoring a wide range of proxy and VPN protocols — from a single VPS to multi-node deployments.
Built as an enhanced fork of the original X-UI project, 3X-UI adds broader protocol support, improved stability, per-client traffic accounting, and many quality-of-life features.

## Features
- **Multi-protocol inbounds** — VLESS, VMess, Trojan, Shadowsocks, WireGuard, Hysteria2, HTTP, SOCKS (Mixed), Dokodemo-door / Tunnel, and TUN.
- **Modern transports & security** — TCP (Raw), mKCP, WebSocket, gRPC, HTTPUpgrade, and XHTTP, secured with TLS, XTLS, and REALITY.
- **Fallbacks** — serve multiple protocols on a single port (e.g. VLESS and Trojan on 443) using Xray's fallback support.
- **Per-client management** — traffic quotas, expiry dates, IP limits, live online status, and one-click share links, QR codes, and subscriptions.
- **Traffic statistics** — per inbound, per client, and per outbound, with reset controls.
- **Multi-node support** — manage and scale across multiple servers from a single panel.
- **Outbound & routing** — WARP, NordVPN, custom routing rules, load balancers, and outbound proxy chaining.
- **Built-in subscription server** with multiple output formats.
- **Telegram bot** for remote monitoring and management.
- **RESTful API** with in-panel Swagger documentation.
- **Flexible storage** — SQLite (default) or PostgreSQL.
- **13 UI languages** with dark and light themes.
- **Fail2ban integration** for enforcing per-client IP limits.

## Quick Start
```bash
bash <(curl -Ls https://raw.githubusercontent.com/mhsanaei/3x-ui/master/install.sh)
```
During installation a random username, password, and access path are generated. After installation, run `x-ui` to open the management menu, where you can start/stop the service, view or reset your login credentials, manage SSL certificates, and more.
For full documentation, please visit the [project Wiki](https://github.com/MHSanaei/3x-ui/wiki).
## Supported Platforms
**Operating systems:** Ubuntu, Debian, Armbian, Fedora, CentOS, RHEL, AlmaLinux, Rocky Linux, Oracle Linux, Amazon Linux, Virtuozzo, Arch, Manjaro, Parch, openSUSE (Tumbleweed / Leap), Alpine, and Windows.
**Architectures:** `amd64` · `386` · `arm64` (aarch64) · `armv7` · `armv6` · `armv5` · `s390x`.
## Database Options
3X-UI supports two backends, chosen during the install:
- **SQLite** (default) — a single file at `/etc/x-ui/x-ui.db`. Zero setup, ideal for small and medium deployments.
- **PostgreSQL** — recommended for high client counts or multi-node setups. The installer can install PostgreSQL locally for you, or accept a DSN to an existing server.
At runtime the backend is selected via environment variables (the installer writes these to `/etc/default/x-ui` for you):
```
XUI_DB_TYPE=postgres
XUI_DB_DSN=postgres://xui:password@127.0.0.1:5432/xui?sslmode=disable
```
### Migrating an existing SQLite install to PostgreSQL
```bash
x-ui migrate-db --dsn "postgres://xui:password@127.0.0.1:5432/xui?sslmode=disable"
# then set XUI_DB_TYPE and XUI_DB_DSN in /etc/default/x-ui and restart:
systemctl restart x-ui
```
The source SQLite file is left untouched; remove it manually once you have verified the new backend.
### Docker
The default `docker compose up -d` keeps using SQLite. To run with the bundled PostgreSQL service, uncomment the two `XUI_DB_*` env lines in `docker-compose.yml` and start with the profile:
```bash
docker compose --profile postgres up -d
```
The image bundles Fail2ban (enabled by default) to enforce per-client **IP limits**. Fail2ban bans offenders with `iptables`, which requires the `NET_ADMIN` capability. `docker-compose.yml` already grants it via `cap_add`; if you start the container with `docker run` instead, add the capabilities yourself, otherwise bans are logged but never applied:
```bash
docker run -d --cap-add=NET_ADMIN --cap-add=NET_RAW ... ghcr.io/mhsanaei/3x-ui
```
