The short version

  • Each has a real cost: Ory Kratos headless means you build every screen, which is significant work compared with a hosted login page; 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: Ory Kratos covers Headless API, 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.

Ory Kratos

  • Products needing complete control over the look and flow of authenticationnot pfSense
  • Applications that must not hand user identity data to a third partynot pfSense
  • Teams building identity as infrastructure across several servicesnot pfSense

pfSense

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

Where each one falls short

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

Ory Kratos

  • Headless means you build every screen, which is significant work compared with a hosted login page
  • More moving parts than a monolithic IAM: Kratos handles identity, and OAuth2 needs Ory Hydra alongside
  • Documentation assumes real familiarity with identity concepts and is not a gentle introduction
  • Self-hosting identity carries the security and availability burden that hosted providers absorb

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

Answered from the vendors’ own pages

Ory Kratos: Is Ory Kratos free?

Yes, open source and free to self-host. Ory Network is a paid managed service.

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.

Ory Kratos: What does headless mean here?

Kratos provides identity flows as APIs and no user interface. You build the login, registration and recovery screens yourself.

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.

Ory Kratos: Does Kratos do OAuth2?

No. Kratos handles user identity; OAuth2 and OpenID Connect provider functionality is Ory Hydra, a separate component.

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.
