3x-ui-Upgrade
Runs the Heimdall panel (an improved 3x-ui version of sh7CBAC)
3x-ui Upgrade is a deployment wrapper for running the Heimdall-enhanced 3x-ui panel on Railway through a single exposed port. It combines the management interface, subscription endpoint, and VLESS over WebSocket traffic behind an Nginx reverse proxy. The container downloads the latest Heimdall build during deployment and starts the required services automatically. SQLite is used by default, keeping the setup simple for modest user counts. Persistent Railway volumes can preserve panel users and inbound settings across redeployments. The included templates and startup script provide a compact path from a GitHub repository to a working hosted instance.
