KubePanel vs CloudPanel
CloudPanel puts "cloud" in the name, but runs on a single VM. KubePanel is built on Kubernetes from the ground up. There's a difference between running on the cloud and being cloud-native.
CloudPanel is modern and lightweight, but limited to a single server. KubePanel delivers true cloud-native architecture.
CloudPanel is a well-designed panel for deploying sites on a single cloud VM. It's fast to set up and supports multiple runtimes. But it cannot provide high availability, automatic failover, or replicated storage because it runs on one machine. KubePanel distributes workloads across a Kubernetes cluster with container isolation, self-healing, and replicated storage across nodes.
Side-by-Side Comparison
CloudPanel CE vs KubePanel across infrastructure, features, and reliability
| Feature | CloudPanel | KubePanel |
|---|---|---|
| Architecture | Single cloud VM | Multi-node Kubernetes cluster Advantage |
| High Availability | Not available | Built-in multi-node Advantage |
| Isolation | Shared OS (vhost separation) | Container-level per domain Advantage |
| Storage | Local disk (single VM) | Replicated (Linstor/DRBD) across nodes Advantage |
| Failover | VM snapshots / manual | Automatic pod rescheduling Advantage |
| Workloads | PHP, Node.js, Python, Static | PHP, Python, Node.js, Django |
| No built-in email | Postfix + Dovecot + DKIM + Rspamd Advantage | |
| Backup | Remote backup (S3, SFTP) | VolumeSnapshot + nightly automated |
| Security | UFW firewall, fail2ban | WAF + L3 + SMTP firewall + geo-blocking Advantage |
| DNS | External DNS only | Cloudflare integration + CRD Advantage |
| SSL/TLS | Let's Encrypt | cert-manager (auto-renewal) |
| Self-Healing | Manual service management | Automatic reconciliation Advantage |
| Node Management | N/A (single server) | Drain, cordon, scale cluster Advantage |
| Monitoring | Basic (disk, CPU, memory) | Per-domain metrics, live traffic, alerts Advantage |
| Open Source | CE edition (MIT) | Source-available |
| Migration Tool | None | Built-in cPanel migration Advantage |
The Architectural Difference
What "cloud-native" really means compared to "cloud-hosted"
Beyond Single-Server
CloudPanel installs on one VM. If that VM goes down, everything goes down. KubePanel spans multiple nodes, so a single node failure doesn't affect your customers. Sites automatically reschedule to healthy nodes.
Replicated Storage
CloudPanel uses local disk on the VM. KubePanel uses Linstor/DRBD replicated storage that synchronizes data across nodes in real-time. Your data survives hardware failures without manual intervention.
Complete Email Stack
CloudPanel has no built-in email. You need external email services or manual Postfix setup. KubePanel includes a full email stack: Postfix, Dovecot, OpenDKIM, and Rspamd with per-domain DKIM signing out of the box.
