The short version

  • Each has a real cost: Jaeger tracing is only as good as the instrumentation, and partial instrumentation produces misleading gaps; pfSense pfSense CE and pfSense Plus are not simply the same software with a support contract layered on top; Plus is a separately developed edition with its own feature set, and moving between them is a migration, not a toggle
  • They diverge on capability: Jaeger covers Distributed trace search, pfSense covers Stateful firewall and NAT.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Jaeger

  • Finding which service in a request path causes the latencynot pfSense
  • Understanding real service dependencies rather than the diagram on the wikinot pfSense
  • Debugging failures that only appear under production traffic patternsnot pfSense

pfSense

  • A home user or small business wanting a free, fully-featured firewall on commodity hardware with no licence costnot Jaeger
  • A business wanting an integrated firewall appliance with vendor support, typically buying a Netgate appliance bundled with pfSense Plusnot Jaeger
  • A team wanting to evaluate advanced features like real-time threat intelligence before committing to Netgate hardware or a Plus migrationnot Jaeger
  • An organisation replacing an expensive commercial firewall with an open source alternative while retaining the option to add commercial support laternot Jaeger

Where each one falls short

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

Jaeger

  • Tracing is only as good as the instrumentation, and partial instrumentation produces misleading gaps
  • Storage is the real operational cost: high-volume tracing on Elasticsearch or Cassandra is a cluster to run and pay for
  • Traces alone, without correlated metrics and logs, leave you switching between tools during an incident

pfSense

  • pfSense CE and pfSense Plus are not simply the same software with a support contract layered on top; Plus is a separately developed edition with its own feature set, and moving between them is a migration, not a toggle
  • Running Plus on non-Netgate hardware depends on Netgate's current migration terms, which have changed over time, so a buyer planning to use white-box hardware with Plus should verify current eligibility rather than assume it works as it did previously
  • CE has no official vendor support channel; a business relying on it for production firewalling without a support contract is self-supporting on community forums
  • Some newer features and threat intelligence integrations are Plus-only, so CE users do not get feature parity going forward even though both editions remain under active development
  • Netgate's own appliance pricing and the terms of the CE-to-Plus migration path are not always clearly presented in one place, requiring some digging to understand the real total cost of a Plus deployment on non-Netgate hardware
  • As with any self-managed firewall, security depends on the operator applying updates and correctly configuring rules; there is no managed security operations layer included even in Plus

Questions people ask

Is Jaeger or pfSense better?
Neither clearly leads. Jaeger starts at Free and pfSense at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Jaeger or pfSense?
Jaeger starts at Free and pfSense at Free.
Does Jaeger or pfSense run on more platforms?
Jaeger runs on Linux, Kubernetes, Docker. pfSense runs on Linux.
Can I use Jaeger for free?
Both have a free tier, so you can try either at no cost before committing.
What is Jaeger best used for?
Jaeger is most often used for finding which service in a request path causes the latency, understanding real service dependencies rather than the diagram on the wiki, debugging failures that only appear under production traffic patterns. Of those, finding which service in a request path causes the latency and understanding real service dependencies rather than the diagram on the wiki are not what pfSense is typically brought in for.
What can Jaeger do that pfSense cannot?
Jaeger covers Distributed trace search, Dependency graph, Adaptive sampling, Pluggable storage. pfSense covers Stateful firewall and NAT, VPN support, Traffic shaping and QoS, Package ecosystem.

Answered from the vendors’ own pages

Jaeger: Is Jaeger free?

Yes, open source and CNCF-graduated. Costs are the storage backend you run.

pfSense: What is the difference between pfSense CE and pfSense Plus?

CE is the free, open source edition installable on any compatible hardware; Plus is a commercial edition from Netgate with additional features and support, typically bundled with Netgate appliances.

Jaeger: Do I use Jaeger or OpenTelemetry?

Both, usually. Instrument with OpenTelemetry and use Jaeger to store and query the traces.

pfSense: Can I run pfSense Plus on my own hardware?

It is possible through a migration from a CE installation via Netgate's official channel, but the terms and availability of that path have changed over time and should be confirmed directly with Netgate.

Jaeger: Does Jaeger handle metrics and logs?

No. It is a tracing system. Metrics and logs need Prometheus, Loki or an equivalent.

pfSense: Is pfSense CE really free with no catch?

Yes, CE has no licence fee and no hardware lock-in, though it comes with community rather than vendor support.
