A Zerto alternative for Proxmox VE
Zerto set the bar for continuous, hypervisor-based replication and slick DR orchestration. Asternodis brings that same near-continuous, low-RPO disaster recovery to Proxmox VE, without the enterprise price tag.
What teams love about Zerto
Zerto's appeal is low-RPO, always-on replication at the hypervisor layer, plus one-click failover, non-disruptive testing, and simple failback. It made DR feel continuous rather than a nightly batch job.
Bringing that to Proxmox
Asternodis replicates your Proxmox VMs near-continuously (from every 10 minutes down to minutes) and adds the orchestration Proxmox lacks: recovery plans, non-disruptive DR testing in an isolated network, and one-click failover and failback across sites. Because it's built on QEMU dirty bitmaps, it protects VMs on any storage backend, not just ZFS or Ceph.

Run DR from either site: one lightweight controller
Zerto's orchestration lives in a ZVM manager at each site, backed by a VRA on every host. Asternodis keeps the same operate-from-either-side resilience in a single lightweight controller per site (no per-host agents) with both sites presenting the identical web UI. Start a failover, DR test, or failback from whichever site you can reach; Asternodis routes each action to the controller that owns it, so there's no split-brain, and the recovery site stays fully in control even if the primary is completely down.
Priced for Proxmox teams
Zerto is priced per-VM for enterprises. Asternodis is priced per DR Site Pair (one production site paired with one recovery site) and business tiers scale on protected nodes, the Proxmox nodes hosting guests you protect. Business licensing starts at $995/year for up to 4 protected nodes, with Business Plus (up to 12) and Enterprise (unlimited) above it, pooled multi-pair packs for MSPs, and unlimited VMs and containers on every tier. Personal, non-commercial home labs run the same software on the $99/year Home Lab license. Every tier includes the full DR feature set. See pricing.
