* fix(flow): restore XTLS Vision when an inbound becomes flow-eligible clientWithInboundFlow strips Vision from a VLESS client whenever the target inbound is not flow-eligible at client-write time — e.g. an XHTTP inbound before its vlessenc (ML-KEM) encryption is set, or a client attached to such an inbound. Nothing restored the flow once the inbound later became eligible: an inbound edit stores its settings verbatim and never re-gates the clients. So enabling encryption on an existing XHTTP inbound left every client without flow, and the generated configs, share links and subscriptions silently dropped flow=xtls-rprx-vision — most visibly on node inbounds and on any inbound where encryption was turned on after the clients existed. Restore the flow at the two points where an inbound can become eligible: - UpdateInbound: after the new stream/settings are final, re-add Vision to clients that currently carry no flow but whose intended flow (their flow_override on a sibling inbound, via EffectiveFlowByEmail) is Vision — only when the inbound is now flow-eligible. - MigrationRestoreVisionFlow: a one-time, idempotent boot migration that applies the same repair to existing installs and refreshes flow_override via SyncInbound. The repair is conservative: it never invents a flow for a client that has none anywhere, never overwrites an explicit flow, and is a no-op on healthy installs. Adds EffectiveFlowByEmail and a unit test covering keep/skip/no-op cases. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * style(flow): serialize restored settings with MarshalIndent Match the indented JSON used by the adjacent timestamp block in UpdateInbound and the externalProxy migration, so a restored inbound's settings column keeps the same multi-line format as everything else (review nit on #5520). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * perf(flow): batch the intended-flow lookup and run it on the active tx restoreVisionFlowForEligibleInbound resolved each empty-flow client's intended flow with EffectiveFlowByEmail, which issued two queries per client (GetRecordByEmail + EffectiveFlow). A client that genuinely uses no Vision keeps an empty flow forever, so it was re-queried on every UpdateInbound and every boot — O(clients) queries per save on a Reality/TCP or XHTTP+vlessenc inbound carrying many non-Vision clients, executed inside the serialized writer transaction. Replace it with EffectiveFlowsByEmails: collect every empty-flow email first and resolve them in a single batched join over client_inbounds + clients (lowest inbound_id wins, same rule as before), chunked for the SQLite bind-var limit. Also thread the active tx through restoreVisionFlowForEligibleInbound so the read runs on the writer's own connection while it holds the lock instead of a separate pooled connection (UpdateInbound passes its tx; the boot migration passes nil → GetDB() as before).

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
