The short version

  • Each has a real cost: ELK Stack the free Basic self managed subscription excludes machine learning, alerting, single sign on via SAML or OpenID Connect, LDAP and Active Directory authentication, field and document level security, searchable snapshots and cross cluster replication; 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.

ELK Stack

  • The free Basic self managed subscription excludes machine learning, alerting, single sign on via SAML or OpenID Connect, LDAP and Active Directory authentication, field and document level security, searchable snapshots and cross cluster replication
  • Cross cluster operations require the same subscription tier on every cluster involved
  • The 99.95 percent monthly uptime SLA applies only to the Platinum and Enterprise subscription tiers
  • Three deployment models are priced on three different bases: resource based for Cloud Hosted, usage based for Serverless and licence based on nodes and RAM for self managed
  • Elastic Cloud Serverless does not yet support traffic filtering, cross project search or bring your own key
  • The pricing page publishes no rate for any tier

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.
