* fix(nodes): stop un-activated nodes from resetting "start after first connect" expiry In a multi-node setup a client is attached to inbounds on several nodes, but its `client_traffics` row is shared per-email (the column is `gorm:"unique"`). With "start expiry after first connect", the expiry is stored as a negative duration and each node converts it to an absolute deadline (now+duration) the first time the client connects *there*. The master's per-node traffic merge wrote `expiry_time = ?` unconditionally for every node sync. So a node where the client never connected keeps reporting the un-activated negative duration and clobbers the absolute deadline that the node where the client *did* connect had already activated — last writer wins. The shared row flip-flops and usually lands back on the negative value, so the main panel shows the timer "not started" while the active node counts down, and the subscription (which reads this row and recomputes negative as now+duration on every fetch) reports a perpetually-resetting, wrong expiry and usage. Guard the merge so an un-activated (<= 0) value reported by a node can never reset an already-activated absolute deadline. A positive node value is still adopted, so a node that legitimately moves the deadline forward (traffic reset / auto-renew) still propagates. The rule lives in both the SQL CASE used by the merge and a small `mergeActivationExpiry` helper (kept in lockstep) that the structural-change check reuses so the guard does not trigger spurious config re-pushes. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(nodes): cast expiry merge params to BIGINT for Postgres The "start after first connect" merge guard introduced the comparison `? <= 0` in the client_traffics expiry_time CASE. There Postgres infers the parameter type as int4 from the literal 0, so binding a real expiry value — a negative start-after-connect duration or a positive absolute deadline (~1.7e12 ms) — overflows int4 and the whole setRemoteTrafficLocked transaction fails, breaking node traffic and expiry sync on Postgres. SQLite (dynamic typing) was unaffected. Wrap both params in CAST(? AS BIGINT) (portable across SQLite and Postgres) so the parameter is typed bigint, matching the explicit casts the sibling GreatestExpr/ClientTrafficEnableMergeExpr helpers already use. Verified against Postgres 16: TestNodeFirstConnectExpiry_NotClobbered failed before this change and passes after; SQLite suite unchanged. --------- Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Co-authored-by: Sanaei <ho3ein.sanaei@gmail.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)
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:
- Cloud-init user-data — unattended install on any cloud (Hetzner/AWS/DO/Vultr/GCP/Azure/Oracle)
- Packer golden image — build an AWS EC2 AMI + qcow2 (amd64/arm64) with per-instance credentials generated on first boot
- Amazon Lightsail — launch script + reusable snapshot builder
- AWS Marketplace checklist
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
