* fix(routing): allow dns.servers on private IPs past the geoip:private block rule Xray's own DNS client traffic is dispatched through the same routing table as proxied client traffic. When dns.servers points at a private IP (e.g. a self-hosted AdGuard Home / Pi-hole reachable on the same Docker network as Xray) and the panel's default geoip:private block rule is active, Xray's own DNS lookups get silently dropped. Xray then falls back to dialing destinations by raw hostname once its internal DNS attempt times out (~4s), so proxied connections still work, just with a multi-second stall added to every new domain-based connection, with no error surfaced anywhere. EnsureDnsServerRouting keeps a managed "direct" allow-rule for any private literal IP found in dns.servers, inserted immediately before the geoip:private block rule (matched by shape, not position). It only acts when both ingredients are present, keeps the managed rule in sync as dns.servers changes across saves, and never touches manually authored rules. Fixes #5773 * fix(routing): scope the DNS allow-rule to its port, guard against reorder/UI drift Addresses three review findings on the initial fix: 1. The allow-rule now carries a "port" matcher (grouped by the dns.servers entries that share it), instead of opening every port on the private DNS IP to proxy-client traffic. A private resolver that also exposes an unauthenticated admin UI on the same address would otherwise become reachable through the proxy too. 2. EnsureDnsServerRouting now strips every previously-managed rule and rebuilds the current set fresh, reinserted immediately before the (re-indexed) geoip:private block rule on every save. Comparing IP content alone missed the case where an admin drags the rule below the block rule in the Routing tab (or reorders something else and incidentally moves it) — silently reintroducing the exact stall this fix addresses, with nothing to notice or correct it. 3. dnsAllowRuleShape now tolerates an "enabled" key as long as it's true, matching the existing EnsureStatsRouting precedent (xray_setting.go's `delete(apiRule, "enabled")`). The Routing tab's rule editor writes that key on every save regardless of whether anything changed, and its enabled switch writes it on a plain toggle — without this, either action permanently disowns the rule from management and a duplicate gets inserted next save. A rule explicitly disabled (enabled=false) is left alone and a fresh one is (re-)created, respecting the admin's choice instead of silently re-enabling it. No-op detection now compares rebuilt rules against the original routing.rules JSON (both decoded through encoding/json to a common type) rather than reflect.DeepEqual on the parsed Go values, which falsely reported changes for identical content stored as []any vs []string. 5 new tests cover multi-port grouping, position drift, and both enabled-key cases; existing tests updated for the port field. * fix: avoid size-computation overflow in allocation hint CodeQL flagged make([]map[string]any, 0, len(clean)+len(managed)) as a potential integer-overflow risk in the capacity computation. Drop the addition and hint with len(clean) alone — it already covers most of the eventual size, and append still grows correctly for the rest. --------- Co-authored-by: Volov <volovdata@google.com>

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, 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 and custom page templates.
- 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 <(curl -Ls https://raw.githubusercontent.com/mhsanaei/3x-ui/master/install.sh)
To install a specific version, append its tag (e.g. v3.4.0):
bash <(curl -Ls https://raw.githubusercontent.com/mhsanaei/3x-ui/master/install.sh) v3.4.0
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.
For full documentation, please visit the project Wiki.
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
