The short version

Only Headscale has a free tier, so it costs nothing to try first.
Each has a real cost: 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.; Splunk no prices are published on any plan; every model requires contacting sales for an estimate
They diverge on capability: Headscale covers Self hosted control server, Splunk covers Log aggregation.

Where each one falls short

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

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.

Splunk

No prices are published on any plan; every model requires contacting sales for an estimate
Three separate pricing models, workload, ingest and entity, so the same deployment costs different amounts depending on which was signed
Ingest pricing bills on data volume, so cost tracks how much you log rather than how much value you get from it
Security, observability and platform are priced separately

Answered from the vendors’ own pages

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.

Splunk: What is Splunk's pricing model?

Splunk offers activity-based, ingest, or workload pricing options depending on the product. Splunk Observability Cloud and AppDynamics use per-host or per-vCPU monthly pricing billed annually. Splunk Cloud Platform and Splunk Enterprise require custom quotes from sales.

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.

Splunk: How much does Splunk Enterprise cost?

Splunk Enterprise pricing requires contact with sales. The vendor offers data-ingest or workload pricing options, supports unlimited users, and can scale to petabytes of data, but specific rates are not published online.

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.

Splunk: What are the differences between Splunk's pricing options?

Splunk offers multiple pricing models: ingest-based pricing charges according to data volume brought into the system; workload-based pricing charges based on computing resources consumed by workloads. Both models apply to Splunk Enterprise and Splunk Cloud Platform. Standard support is included with product purchases; premium support is available as an add-on.

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.
