Proxmox Datacenter Manager vs ProxCenter: What Each One Does
Proxmox now ships its own multi-cluster tool, so where does ProxCenter fit? Here is an honest breakdown of what PDM and ProxCenter each do, where they overlap, and why many fleets run both.
Two tools born from the same problem
Anyone managing more than one Proxmox VE cluster knows the limitation: Proxmox's excellent web interface is per-cluster. Ten clusters means ten browser tabs, ten separate credential sets, and no consolidated view of anything.
Two products now address this gap, and prospects ask us about the difference weekly, so let us answer it properly.
Proxmox Datacenter Manager (PDM) is built by Proxmox Server Solutions GmbH, the makers of Proxmox VE itself. After an alpha in December 2024 and a beta in September 2025, PDM reached its stable 1.0 release in December 2025, followed by version 1.1 in May 2026. It is fully open source under AGPLv3, ships as a Debian-based appliance written largely in Rust, and connects Proxmox VE and Proxmox Backup Server instances as "remotes".
ProxCenter is our datacenter management platform for Proxmox VE fleets, built for enterprise operations, regulated environments, and MSPs. It deploys as a containerized stack (Next.js frontend, Go orchestrator, PostgreSQL) and connects to your clusters through the Proxmox API.
The short version of this article: these products overlap on the dashboard and diverge almost everywhere else. PDM is centralized visibility and infrastructure lifecycle from the vendor itself. ProxCenter is an operations platform: delegation, compliance, automation, migration tooling, and multi-tenancy. Many of our customers run both, and we consider that a perfectly good architecture.
What PDM does well
Credit where due, because there is real substance here:
- Consolidated visibility. PDM aggregates health, resource usage and KPIs across all connected remotes into a single dashboard, with locally cached data that keeps the last known state visible even when a remote is offline. Version 1.1 added native Ceph monitoring across clusters (OSDs, monitors, managers, MDS, pools, CephFS and cluster flags) and a cross-remote guest list with filtering and common per-guest actions.
- Cross-cluster live migration. Moving a running VM between independent clusters from a central interface is genuinely useful, and PDM does it.
- Centralized SDN (EVPN). Configuring EVPN zones and VNets across multiple remotes from one place simplifies overlay networking in distributed setups.
- Infrastructure lifecycle. Version 1.1 brought centralized management of automated installations (answer files served to remotes, install progress tracked centrally), which is a genuinely differentiated capability nobody else has, because nobody else builds the installer.
- First-party trust. It comes from the vendor, follows the Debian release cycle with roughly three years of support per major version, and costs nothing.
If your need is "see all my clusters in one place and move VMs between them", PDM answers it, and you should use it.
Where the two products diverge
The divergence starts the moment your question changes from "what is the state of my fleet?" to "how do I run operations on this fleet with a team, under constraints?"
Delegation and access control
PDM is currently a tool for administrators: the people who log into it are trusted operators. ProxCenter is built around multi-cluster RBAC: roles with scoped permissions across the fleet, role-level default scopes, LDAP and OIDC integration with group mapping, SSO-only login policies, enforced TOTP two-factor, and a PostgreSQL audit trail recording who did what, where, and when. The moment you have junior admins, an outsourced NOC, a security team asking for audit evidence, or customers, this layer stops being optional.
Compliance
ProxCenter assesses your connections against NIST 800-53 r5, NIST 800-171 r2, CMMC Level 2 and ISO/IEC 27001:2022, with per-node results and exportable PDF reports built from a check-to-control crosswalk over its hardening checks. For healthcare, public sector, defense supply chain, or any audited environment, this is the difference between a screenshot and a deliverable.
VMware exit tooling
ProxCenter includes a migration pipeline from VMware sources (ESXi-direct and vCenter, including vSAN): warm migration with changed-block tracking and a final delta sync, preserved MAC addresses, preflight go/no-go checks, and bulk operation. XCP-ng, Nutanix and Hyper-V sources are supported as well. PDM manages Proxmox remotes; migrating into Proxmox from another hypervisor is outside its scope. In 2026, with Broadcom renewals forcing decisions, this is frequently the reason a ProxCenter evaluation starts.
Automatic workload balancing
ProxCenter's DRS continuously evaluates load across clusters and executes rebalancing with per-cluster migration caps, per-target inflow limits, affinity rules and maintenance evacuation. PDM's guest orchestration is at its initial phase by Proxmox's own description, focused on day-to-day actions rather than automated placement policy.
Multi-tenancy for MSPs
ProxCenter's vDC module gives tenants a cloud-style cockpit with quota enforcement, native IPAM with automatic IP and MAC reservation, per-tenant PBS bindings with auto-provisioned namespaces and ACLs, tenant-scoped backup jobs, and white-labeled per-tenant reports. PDM has no tenant concept: every user sees the infrastructure as infrastructure.
Operational reporting and observability
ProxCenter ships scheduled PDF reporting (capacity, inventory, compliance, security, utilization, site recovery), an alerting engine with thresholds and silences, sFlow/OVS network flow visualization with Sankey diagrams, site recovery orchestration with scheduled replication, and rolling cluster updates with health verification. PDM's reporting is its dashboard.
The honest overlap table

PDM's roadmap is public and moving (deeper PBS integration, Proxmox Mail Gateway remotes, off-site replication copies are all listed), so expect the left column to grow. We update this comparison as it does.
So which one should you run?
Run PDM alone if you are a small team of trusted administrators, your need is consolidated visibility and occasional cross-cluster migration, and features from the bottom half of the table are not on your requirements list. It is free, first-party, and good at what it does.
Add ProxCenter when any of these become true: you need to delegate access with real RBAC and prove it with an audit trail; an auditor or a customer asks for compliance evidence; you are migrating off VMware and want tooling rather than scripts; you operate as an MSP with tenants; or you want the fleet to balance and report on itself instead of being watched.
Running both is not a contradiction. PDM costs nothing and its installation management and first-party Ceph views are useful regardless. Several of our customers keep PDM as the infrastructure engineer's console and ProxCenter as the operations platform the wider team and the auditors interact with. The two connect to the same Proxmox APIs and do not conflict.
Our position has not changed since Proxmox began shipping native fleet features: we build on top of what Proxmox provides, not against it. When the platform grows a native capability, ProxCenter integrates with it rather than competing with it. PDM makes the Proxmox ecosystem stronger, and a stronger Proxmox ecosystem is exactly the market we serve.
FAQ
Is ProxCenter a fork or wrapper of PDM? No. They are independent products with different codebases. Both talk to the Proxmox VE API.
Does ProxCenter require PDM? No. ProxCenter connects directly to your clusters. They can coexist on the same fleet without conflict.
Is PDM going to make ProxCenter redundant? PDM's published roadmap centers on visibility, lifecycle and Proxmox-family integration. RBAC delegation, compliance evidence, VMware exit tooling and MSP multi-tenancy are a different problem space, and it is the one we build for. We revisit this comparison with every PDM release.
Which one do I try first? Both, honestly. PDM is a free download from proxmox.com, and ProxCenter's Community edition is free as well. For the Enterprise features, a trial only requires your node count.
