The short version

  • Each has a real cost: Grafana the free tier retains metrics, logs and traces for 14 days only; Headscale the clients are proprietary software maintained by a company with no obligation to Headscale, so a client update can change protocol behaviour and break your control server until volunteers catch up.
  • They diverge on capability: Grafana covers Dashboard creation, Headscale covers Self hosted control server.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Grafana

  • The free tier retains metrics, logs and traces for 14 days only
  • Free is capped at 10,000 active metric series and 50 GB each of logs and traces a month
  • The Pro plan carries a $19 a month platform fee before any usage charges
  • Logs and traces are billed on three separate meters, at $0.050 per GB processed, $0.400 per GB written and $0.100 per GB retained
  • Retaining data is an ongoing charge rather than a one off, so historical data costs every month it exists

Headscale

  • The clients are proprietary software maintained by a company with no obligation to Headscale, so a client update can change protocol behaviour and break your control server until volunteers catch up.
  • Features that live on the vendor side, including the admin console, Funnel and app connectors, do not exist here and cannot be added, so feature comparisons against Tailscale are misleading.
  • There is no official web interface, so day to day administration is a command line tool or one of several unofficial front ends of varying quality and maintenance.
  • It is deliberately single tenant, so a managed service provider cannot use one deployment to serve several customer networks.
  • Upgrades have required database migrations and policy format changes between releases, and with no support contract a failed migration on the control server is your problem alone.

Answered from the vendors’ own pages

Grafana: What is Grafana's pricing model?

Grafana offers a freemium model with a free tier, Pro tier starting at 19 USD/month with pay-as-you-go usage charges, and Enterprise plans starting at 25000 USD/year.

Source
Headscale: Is Headscale made by Tailscale?

No. It is an independent community project. Tailscale acknowledges it but does not support it, and the clients it relies on are the vendor ones.

Grafana: How long is data retention for each plan?

Free tier provides 14-day retention for metrics, logs, traces, and profiles. Pro tier extends this to 13 months for metrics and 30 days for logs/traces/profiles. Enterprise offers custom retention options.

Source
Headscale: What do I lose compared with the hosted service?

The admin console, the vendor relay network unless you use the public DERP servers, and hosted only features such as Funnel and app connectors.

Grafana: What support is included in each tier?

Free tier includes community support only. Pro tier provides 8 times 5 email support. Enterprise includes premium 24/7 support.

Source
Headscale: Can I still use the public relay servers?

Yes, the default configuration can use them, though many self hosters run their own DERP to remove that dependency.

Grafana: Does Grafana offer volume discounts?

Yes, Grafana uses adaptive pricing with automatic volume discounts as usage scales, and provides cost-optimization tools to help eliminate spending on unused data.

Source
Headscale: Is it suitable for a company network?

For a technical team, yes. There is no vendor to escalate to, so it needs someone on staff who is willing to own the control server.
