CELERITY Panel puts every Hysteria 2 and Xray VLESS node you run behind one clean web panel, so a fleet of proxy servers behaves like a single service. Add a node and the panel connects over SSH to install the software, certificates, and port hopping for you. Server groups map users to the nodes they may use, and load balancing spreads them by real server load. Cascade topology chains servers together, so clients connect to one node while traffic exits through another, drawn on a visual network map. Traffic rules block advertising domains and unwanted destinations or route selected traffic through custom proxies. Each user receives a subscription link that formats itself for Clash, Sing-box, Shadowrocket, and Hiddify. The dashboard watches online users, traffic volume, and node health in real time, and an in-browser SSH terminal reaches any node without leaving the panel. Programmatic control comes through scoped API keys with IP allowlists and rate limits, signed webhooks announce events as they happen, automatic backups land on S3-compatible storage, and AI assistants can operate the panel through its MCP interface. Two-factor authentication protects the admin login. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
