updateInboundClientIps wrote the [LIMIT_IP] lines that drive the jail while the scan's transaction was still open, and marked the addresses in bannedSeen at the same time. A commit failure after that point rolls the database back but takes nothing back from the log: fail2ban proceeds to ban addresses the panel never recorded, and the in-memory bannedSeen entry makes the next scan skip them, so the rollback is never repaired. Selection stays inside the transaction. processObserved now collects one pendingBan per enforced client and publishes after the commit succeeds, disconnecting only the clients whose lines actually reached the log. The Xray disconnects already ran after the commit for the same reason. Recording moved with the write rather than with the decision: selectAdvancedSinceLastBan no longer mutates anything, and recordBannedSeen runs once a line is on disk. It also runs for clients with nothing to ban, because that is the pass that forgets addresses a client no longer exceeds its limit with - pruning used to be a side effect of the filter, and skipping it left a stale entry that suppressed the next legitimate ban. The log file is opened once per scan instead of once per client, the write error is checked instead of discarded, and Close is reported. updateInboundClientIps no longer reports shouldCleanLog, because the only thing that set it was the ban branch that moved out; processObserved sets it when a publication actually happens. disAllowedIps went with the write it served. Tests: a transaction failed at COMMIT through a deferred foreign key leaves no line and no bannedSeen entry; a publication that cannot open the log leaves the address retryable; a client returning under its limit has its entry forgotten, so going over again is banned a second time; a committed over-limit scan publishes and reports; and writeBanLines surfaces a write error rather than swallowing it.

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
