* feat(model): add MemberWeights to SubBalancer Per-inbound leastLoad weights, stored with the same gorm json serializer as InboundIds so AutoMigrate adds the text column on every dialect (postgresModelSettled sees the missing column and re-runs). Absent entries mean weight 1.0; only meaningful for strategy leastLoad. * feat(sub): accept memberWeights on the sub-balancer API Parsed as one JSON form field (gin cannot bind bracket-keyed maps from urlencoded bodies). validate() rejects weights under any strategy but leastLoad — xray would silently ignore costs there, so storing them would pretend a knob exists. Non-positive weights error instead of defaulting: a zero usually means a typo'd "never pick this node". Entries for inbounds no longer selected are dropped on save. * feat(sub): emit leastLoad strategy costs from member weights costs[] is built after the tagging loop reuses the exact retagged tags (bal-N-protocol[-k]) and each member's owning inbound id. Members without a configured weight default to 1.0, but costs are omitted entirely unless at least one explicit weight survives — an all-1.0 array would bloat every subscription response for no effect. * feat(sub-balancers): leastLoad member weight inputs Weight fields render only under leastLoad and hide on strategy change without dropping their values, so an accidental toggle away and back loses nothing until save; non-leastLoad submits strip them entirely because xray would ignore costs. Weights travel as one JSON form field (gin cannot bind bracket-keyed maps) and every locale gets the three new keys in the same commit per the dead-keys rule. * docs(api): document memberWeights on sub-balancers leastLoad-only JSON form field; update notes that omitting it clears stored weights. Regenerated openapi artifacts via make gen + the docs copy/gen:api step nothing checks automatically. * fix(api-docs): use the allowed object ParamType for memberWeights * fix(sub-balancers): cap the member-weight list height Many selected inbounds pushed the modal body past the viewport. The weight rows now scroll inside a 220px viewport, mirroring the inbound picker's listHeight so both lists read the same. * fix(sub): anchor leastLoad cost matches to exact member tags Verified against xray-core: without regexp, WeightManager matches costs by substring (strings.Index), so the bare tag "bal-1-vless" also hits the deduplicated "bal-1-vless-2" and both members get the first entry's weight. Anchored ^tag$ regexps make every cost entry match only its own member. Also confirmed value<=0 makes xray derive a weight from the first digit of the matched tag — validating weights > 0 server-side was the right call. * fix(sub-balancers): keep member weights across the enabled toggle The table's toggleEnabled re-posted a full-row payload without memberWeights, and the update path treats an absent key as "erase" — flipping the switch silently dropped every configured weight. Round-trip the stored weights through the toggle payload, and prove persistence with a re-Get in the weight-validation test (the returned struct alone would stay green even if Save skipped the column). * fix(sub-balancers): address review on member weights - omitempty on MemberWeights: the panel sends null for every pre-existing and non-leastLoad balancer, which failed the hand-written zod response schema on every fetch (zod .optional() accepts undefined only; switched to .nullish() per repo convention) and drifted the generated contract. Regenerated openapi artifacts + docs copy + MDX. - Bound weights to the positive float32 range: xray decodes costs as float32, so an over-range value makes clients reject the whole subscription document and an underflow decays to the tag-digit fallback weight. Tests for both directions. - Trim six comment blocks to the 2-line cap from CLAUDE.md. --------- Co-authored-by: DIMFLIX <dimflix@users.noreply.github.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.
Screenshots
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
