MHSanaei/3x-ui

3X-UI is a web control panel for managing Xray-core proxy and VPN servers.

The tool addresses the need to deploy and manage multiple proxy protocols across single or distributed server infrastructure. It works by providing a centralized web interface built on top of Xray-core, handling protocol configuration, user management, and traffic monitoring. The panel supports numerous protocols including VLESS, VMess, Trojan, Shadowsocks, WireGuard, Hysteria2, HTTP, and others, with modern transport options like WebSocket, gRPC, and XHTTP secured through TLS, XTLS, and REALITY. A distinctive feature is per-client traffic accounting with quotas, expiry dates, and IP limits, alongside the ability to run fallbacks that serve multiple protocols on a single port.

Adoption suits operators managing proxy infrastructure who need granular per-client control and multi-protocol flexibility. The tool handles both single-server and multi-node deployments from one panel. It includes a subscription server with custom templates, Telegram bot integration for remote management, and a RESTful API. The project explicitly states it is intended for personal use only and should not be used for illegal purposes or in production environments.

The project maintains active development with regular releases and passing build workflows. Documentation is available in multiple languages and includes detailed guides for advanced features like custom subscription templates. The codebase is written in Go and accepts contributions through standard GitHub workflows.
