NetBird vs Splunk
NetBird
Networking
Open source WireGuard mesh VPN with identity based access policies and a hosted control plane
- From
- Free
- Rated
- -
The short version
- Only NetBird has a free tier, so it costs nothing to try first.
- Each has a real cost: NetBird self hosting requires an identity provider, and the bundled option adds a second unfamiliar service to operate, so the free path costs more administrative time than the docker compose file suggests.; Splunk no prices are published on any plan; every model requires contacting sales for an estimate
- They diverge on capability: NetBird covers WireGuard data plane, Splunk covers Log aggregation.
- 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.
NetBird
- Self hosting requires an identity provider, and the bundled option adds a second unfamiliar service to operate, so the free path costs more administrative time than the docker compose file suggests.
- Peers that cannot connect directly fall back to relays, and on a self hosted deployment that relay bandwidth is your cost and your bottleneck rather than an included service.
- If the self hosted management server is down, existing tunnels keep working but no new peer can join and no policy change takes effect, which makes it a component that needs its own availability plan.
- Some capabilities aimed at larger organisations sit in the paid cloud tiers, so a self hosted deployment does not have exactly the same feature set as the hosted one.
- The project moves quickly and configuration and deployment layouts have changed between versions, so self hosted upgrades need reading release notes rather than pulling a new image.
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
NetBird: Is the self hosted version crippled?
No. The management, signal and relay components are all open source and the network works without any NetBird operated service.
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.
SourceNetBird: How does it differ from Tailscale?
Similar model and similar clients, but Tailscale keeps its coordination server proprietary. NetBird publishes its whole control plane, which is the reason most self hosters choose it.
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.
SourceNetBird: Do I need to open firewall ports?
No inbound ports are required. Peers make outbound connections to the signal service and to each other.
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.
SourceNetBird: What happens to traffic if NetBird the company disappears?
On a self hosted deployment, nothing, since you run every component. On the cloud service you would need to stand up your own control plane and re-enrol peers.
