The short version
- Each has a real cost: Consul namespaces, admin partitions and other multi tenancy controls are Consul Enterprise 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: Consul covers Service discovery, Headscale covers Self hosted control server.

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
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
Consul: How much does Consul cost?
Consul does not publish specific pricing. The open source Community edition is free. HashiCorp also offers a Consul Enterprise edition, but pricing details are not disclosed publicly and must be obtained by contacting HashiCorp sales.
SourceHeadscale: 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.
Consul: Is Consul open source?
Consul includes a free, open source Community edition. HashiCorp also offers a proprietary Enterprise edition for organizations requiring advanced features, but no public pricing is available for the Enterprise version.
SourceHeadscale: 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.
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.
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.
