The short version

  • Each has a real cost: Tailscale requires active configuration and management; cannot be deployed passively like consumer VPNs; VictoriaMetrics promQL compatibility is very close but not identical, and MetricsQL extensions do not port back

Where each one falls short

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

Tailscale

  • Requires active configuration and management; cannot be deployed passively like consumer VPNs
  • Device posture policies and JIT access tiers are locked behind Premium subscription (£18/month), raising per-user costs for enterprises
  • Limited support for legacy protocols and non-modern operating systems (Windows 7, older Android versions)
  • Centralised control plane operated by Tailscale (hosted in US); no self-hosted control plane option for air-gapped or sovereign deployments
  • Cannot replace full VPN functionality for accessing legacy IP-based services; only applicable to modern infrastructure

VictoriaMetrics

  • PromQL compatibility is very close but not identical, and MetricsQL extensions do not port back
  • Smaller community than Prometheus, so fewer guides and third-party integrations
  • The clustered version has meaningfully more moving parts than the single binary suggests
  • Some enterprise features sit outside the open-source offering

Answered from the vendors’ own pages

Tailscale: Is Tailscale free?

Tailscale Personal tier is free forever for up to 6 users. Standard (£8/month per user) adds team features, Premium (£18/month per user) adds security controls, and Enterprise tiers are custom priced.

Source
VictoriaMetrics: Is VictoriaMetrics free?

The open-source version is free with no data limits. An enterprise edition and cloud service are paid.

Tailscale: Does Tailscale route all traffic through a central gateway?

No. Tailscale creates direct encrypted connections between devices using WireGuard. It only proxies traffic when direct peer connections are not possible (some restrictive NAT scenarios). This reduces latency and eliminates VPN gateway bottlenecks.

Source
VictoriaMetrics: Does it replace Prometheus?

It can, but most teams keep Prometheus for scraping and use VictoriaMetrics as the long-term store behind it.

Tailscale: Can I host Tailscale on-premises?

No. Tailscale provides a hosted control plane only. For fully self-hosted mesh networking, consider WireGuard with manual key management or Netmaker. Tailscale Enterprise can provide custom deployments for specific requirements.

Source
VictoriaMetrics: Is PromQL fully supported?

Very nearly. It implements PromQL and extends it with MetricsQL, though a small number of edge-case behaviours differ.
