The short version

  • Each has a real cost: Consul namespaces, admin partitions and other multi tenancy controls are Consul Enterprise only; Tailscale requires active configuration and management; cannot be deployed passively like consumer VPNs

Where each one falls short

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

Consul

  • Namespaces, admin partitions and other multi tenancy controls are Consul Enterprise only
  • Audit logging, OIDC authentication and FIPS 140-2 builds require Consul Enterprise, so compliance driven deployments cannot use the free edition
  • Automated backups, redundancy zones, read replicas and automated server upgrades are Enterprise only
  • Long Term Support releases are Enterprise only, so community users must upgrade to stay supported
  • Service mesh and advanced traffic management sit in the Premium Enterprise tier above Standard Enterprise
  • HashiCorp does not publish a Consul rate on its pricing page, which lists per resource prices for Terraform instead

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

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.

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
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.
