metacubexd gives your Mihomo proxy kernel a proper control room in the browser, from live traffic graphs to a full YAML profile editor. Real-time panels show upload and download speed, totals, active connections, memory use, and the busiest proxies, plus your current exit IP and latency to Google, Cloudflare, and GitHub. Proxy groups appear as cards with per-node latency bars, so switching a selector or running a latency test takes one click. Every connection is listed with its host, process, matched rule chain, and traffic, and can be closed or exported to CSV or JSON. Rules are searchable and filterable by type, and individual rules can be toggled on or off. Live logs stream by level, ready to search or download. With the all-in-one server image, you can also create profiles, import subscriptions by URL, edit configuration with schema-aware completion, validate it, and restart the kernel from the same page. Thirty-two themes, custom CSS, keyboard shortcuts, a responsive mobile layout, and seven interface languages make it comfortable to use anywhere. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
