The short version

  • Only Galileo has a free tier, so it costs nothing to try first.
  • Each has a real cost: Galileo the free plan is limited to 5,000 traces per month, which is quickly outgrown by production workloads.; 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.

Galileo

  • The free plan is limited to 5,000 traces per month, which is quickly outgrown by production workloads.
  • Real-time guardrails and unlimited trace capacity are reserved for the custom-priced Enterprise tier.
  • Pro plan pricing scales with trace volume, so costs can grow unpredictably as usage increases.
  • On-premises deployment requires an Enterprise contract rather than being available self-serve.

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
