The short version

  • Each has a real cost: CloudWatch the free tier covers 5 GB of log ingestion and 10 custom metrics a month, after which log ingestion is $0.50 per GB from 5 to 30 GB; 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.

CloudWatch

  • The free tier covers 5 GB of log ingestion and 10 custom metrics a month, after which log ingestion is $0.50 per GB from 5 to 30 GB
  • Custom metrics are $0.30 each for the first 10,000, so instrumenting broadly gets expensive before volume discounts apply
  • Each custom dashboard beyond the free three is $3 a month
  • Alarms are billed at $0.10 per alarm metric a month, with high-resolution alarms costing more
  • Log storage beyond the free 5 GB is $0.03 per GB per month on top of the ingestion charge

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.

Source
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.
