Handing a teammate the keys to a Proxmox cluster usually means handing over far too much, so pvecenter puts a narrower, self-service web panel in front of it. The dashboard shows node health, CPU, memory, storage, and recent tasks, and several Proxmox hosts can be managed from one place. Virtual machines are created through a guided wizard or in batches, then powered, cloned, migrated, resized, snapshotted, and reached through an in-browser console. LXC containers get their own pages, and a template pipeline builds cloud-init templates from cloud images. Bridges, VLANs, address pools, and the native Proxmox firewall are managed with rule templates pushed to many guests at once. Backups can run now or on a schedule, with restore, delete protection, and integrity checks. Administrators define reusable resource sizes, per-user quotas, roles, two-factor sign-in, and an audit log of every write. A security baseline scores hosts and offers guided hardening, SSH brute-force protection bans repeat offenders, and an AI inspection assistant explains findings and asks approval for every change. Alerts reach email, Feishu, and webhooks, and certificates renew automatically. The interface is Chinese-first, with a language switch and an English guide. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.
