The short version

  • Only Deno has a free tier, so it costs nothing to try first.
  • Each has a real cost: Deno egress bandwidth overage costs $0.20/GB which can become expensive for high-traffic applications; Proxmox VE per-socket licensing model: cost scales with CPU socket count, not vCore count, resulting in high costs for multi-socket servers

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Deno

  • Egress bandwidth overage costs $0.20/GB which can become expensive for high-traffic applications
  • CPU time overage is $0.10/hour on Pro and Builder tiers, adding to costs for compute-intensive workloads
  • Enterprise pricing is not disclosed; requires sales contact

Proxmox VE

  • Per-socket licensing model: cost scales with CPU socket count, not vCore count, resulting in high costs for multi-socket servers
  • Linux-based host only; Windows hypervisors not supported, limiting adoption in Windows-focused organisations
  • Clustering and high-availability setup requires operational expertise and careful network configuration
  • Commercial support tiers limit advanced features (just-in-time access, network flow logs) to paid subscriptions
  • Smaller ecosystem of third-party plugins and integrations compared to VMware vSphere
