Sanaei 679d2e1cca fix: resolve a batch of open bug-tagged issues (traffic accounting, share strategy, sub address, CPU) (#5477)
* fix(node): never re-add a node's full counter on reset/restart (#5456, #5476, #5390)

When a node's per-client counter dips below the master's stored baseline
(node reboot, xray restart, or a reset propagated to the node), the delta
accounting clamped delta to the node's whole current counter and re-added it
to the master total — double-counting a client's lifetime usage in a single
sync and often pushing them over quota. Treat a backward-moving counter as a
reset: add 0 and rebaseline to the reported value, so only genuine post-reset
usage accrues.

Resets also now clear the per-node NodeClientTraffic baseline (ResetClient
TrafficByEmail, resetClientTrafficLocked, BulkResetTraffic, resetAllClient
TrafficsLocked), mirroring the delete paths. Without this the node's pre-reset
cumulative — including traffic it had counted but not yet synced — leaks back
onto the master after a reset, which is the 'reset reverts after a while'
report. The next sync then takes the clean delta=0 + rebaseline path regardless
of node state.

Updates TestNodeCounterReset (was _Clamped, now _NoReAdd) to assert rebaseline
instead of re-add, and adds TestCentralResetClearsNodeBaseline_NoLeak.

* fix(inbound): keep persisted node share strategy on edit (#5375)

Opening the edit modal silently reverted shareAddrStrategy from 'node' to
'listen'. The downgrade effect fires before the form settles: availableNodes
is an empty placeholder until /nodes/list resolves, and Form.useWatch('protocol')
is briefly empty on the first edit render — both transiently make the node
option look unavailable, so the effect clobbered the saved value.

Gate the downgrade on availableNodesFetched (threaded from useNodesQuery through
InboundsPage) and on the protocol watch being settled, so a persisted strategy
is only downgraded when the node option is genuinely unavailable. Adds a
rerender-based regression test covering the nodes-loading race.

* perf(traffic): skip cross-panel quota subquery when no globals exist (#5392, #5389)

disableInvalidClients ran a correlated EXISTS against client_global_traffics
on the full client_traffics table every 5s. On a panel no master pushes to,
that table is empty so the subquery can never match — yet it forced a full
scan that pegged Postgres at 100% CPU on large client counts. Probe the table
first and drop the EXISTS branch when it's empty (the common case), and add an
idx_client_global_email index so the subquery is an index lookup when globals
are present. Cross-panel enforcement is unchanged (TestGlobalUsage_DisablesClient).

This also relieves #5389 ('traffic writer queue full' / panel freeze): the
heavy query runs inside the serialized traffic write, so a slow DB backs the
shared writer queue up until request handlers block.

* fix(sub): don't advertise a leaked client IP for local wildcard inbounds (#5425)

For a local inbound with no node, no custom share address, and a wildcard/blank
listen, resolveInboundAddress fell straight through to the subscriber's request
host. Behind NAT/proxy/CDN that Host can be the requesting client's own IP, so
the subscription wrote the client's address into the inbound instead of the
server's — while the panel's own share link (which doesn't use the request host)
stayed correct.

Prefer the admin's configured public host (Sub/Web domain) over the raw request
host for this last-resort fallback. With no configured host the request host
still stands, so existing single-domain setups are unaffected.

3x-ui

Release Build GO Version Downloads License Go Reference Go Report Card

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)

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 & cloud images

The installer also runs non-interactively for cloud-init and golden images. 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:

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

Environment Variables

Variable Description Default
XUI_DB_TYPE Database backend: sqlite or postgres sqlite
XUI_DB_DSN PostgreSQL connection string (when XUI_DB_TYPE=postgres)
XUI_DB_FOLDER Directory for the SQLite database file /etc/x-ui
XUI_DB_MAX_OPEN_CONNS Maximum open connections (PostgreSQL pool)
XUI_DB_MAX_IDLE_CONNS Maximum idle connections (PostgreSQL pool)
XUI_INIT_WEB_BASE_PATH The initial URI path for the web panel /
XUI_ENABLE_FAIL2BAN Enable Fail2ban-based IP-limit enforcement true
XUI_LOG_LEVEL Log verbosity (debug, info, warning, error) info
XUI_DEBUG Enable debug mode false

Supported Languages

The panel UI is available in 13 languages:

English · فارسی · العربية · 中文(简体) · 中文(繁體) · Español · Русский · Українська · Türkçe · Tiếng Việt · 日本語 · Bahasa Indonesia · Português (Brasil)
