* fix(xray): place the freedom domain strategy where the core reads it freedom resolves through the socket layer, so xray-core reads sockopt.domainStrategy and treats both other placements as legacy: it warns on every config load for the outbound-root targetStrategy it migrates itself, and again for the settings-level domainStrategy it deprecates. The panel wrote exactly those two keys from its Freedom Protocol Strategy select, the outbound form card, and the IPv4 routing helper, so any install that had configured a strategy logged a deprecation warning on every start. The strategy now travels in streamSettings.sockopt everywhere the panel emits it: the Basics select, the outbound form (including the JSON tab, which shares the same adapter), the shipped default template, and the IPv4 outbound the routing helper injects. Reading mirrors the loader's own order — root targetStrategy, then the settings keys, then sockopt — so the card keeps showing the value the core would actually run with, and saving drops the legacy keys instead of leaving them behind. A seeder moves the keys for configs already stored in the database, following OutboundRemovedKeysFix. The shared outbound-root Target Strategy field is hidden for freedom, since the core migrates that key into the very sockopt value the card writes and two knobs for one value would race. Tests: placement round-trips and the migration table run through the real vendored core (a captured log handler proves the warning is gone after the rewrite and present before it), and the modal asserts freedom offers a single strategy field. * test(database): seed the template row the seeder test needs A fresh InitDB creates no xrayTemplateConfig row — the panel's setting defaults live in the service layer — so the test has to insert the legacy template itself and then assert the seeder's history gate stops a second pass from rewriting it. * fix(xray): keep one strategy control per outbound, seed the row in tests Review findings: the Transport tab's Sockopts block renders for freedom too, so its Domain Strategy select and the freedom card wrote one sockopt value between them and the card won on save — the field is hidden for freedom now, leaving the card as the single control. The seeder is also pre-marked on a fresh install so it does not run on the second start, and the seeder test seeds the template row itself (a fresh InitDB has none) and asserts the rewrite structurally instead of grepping for a key name that sockopt also uses.

3X-UI is an advanced, open-source web control panel for managing 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.
Important
This project is intended for personal use only. Please do not use it for illegal purposes or in a production environment.
Features
- Multi-protocol inbounds — VLESS, VMess, Trojan, Shadowsocks, WireGuard, AmneziaWG, TUIC v5, Hysteria2, MTProto, 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.
- AmneziaWG built in — DPI-resistant WireGuard runs inside the panel on a userspace network stack, with no kernel module, DKMS, or extra packages to install.
- TUIC v5 sidecar — High-performance QUIC-based proxy with native UDP relay traffic metering, 0-RTT handshakes, and BBR congestion control.
- MTProto proxies — per-client FakeTLS secrets, ad-tags, and quotas, applied live without dropping existing connections.
- 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 with trusted-address exemptions, HWID device limits, scheduled renewal cycles, 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, including cloning inbounds onto other nodes.
- Outbound & routing — WARP, NordVPN, PIA, custom routing rules, load balancers with balancer-to-balancer fallback, and outbound proxy chaining. Bundled geosite and geoip categories are browsable straight from the rule editor.
- Built-in subscription server — raw, JSON, and Clash output, auto-selected from the client's User-Agent, plus custom page templates.
- Telegram and Discord bots for remote monitoring and management.
- RESTful API with scoped, optionally expiring tokens and an in-panel API reference.
- Installable panel (PWA) — pin 3X-UI to a desktop or phone home screen.
- 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 <(curl -Ls https://raw.githubusercontent.com/mhsanaei/3x-ui/master/install.sh)
To install a specific version, append its tag (e.g. v3.7.0):
bash <(curl -Ls https://raw.githubusercontent.com/mhsanaei/3x-ui/master/install.sh) v3.7.0
To install the rolling dev build (latest per-commit pre-release from main, not a stable release), pass dev-latest:
bash <(curl -Ls https://raw.githubusercontent.com/mhsanaei/3x-ui/master/install.sh) dev-latest
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.
Every release asset is published with a .sha256 sum next to it. Both install.sh and the updater verify the archive against that sum and abort on a mismatch.
For full documentation — installation, configuration, operations, and the complete API reference — visit docs.sanaei.dev.
Unattended install
The installer also runs non-interactively for cloud-init.
Set XUI_NONINTERACTIVE=1 (or pipe with no TTY) and it installs end-to-end with
zero prompts, generating random credentials and writing them to
/etc/x-ui/install-result.env. See deploy/ for:
- Cloud-init user-data — unattended install on any cloud (Hetzner/AWS/DO/Vultr/GCP/Azure/Oracle)
- Hetzner Cloud notes — cloud-init deployment on Hetzner
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
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:
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:
docker run -d --cap-add=NET_ADMIN --cap-add=NET_RAW ... ghcr.io/mhsanaei/3x-ui
