The short version

  • Each has a real cost: Arch Linux installation and maintenance assume real Linux knowledge; there is no hand-holding by design; 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: Arch Linux covers Rolling release, pfSense covers Stateful firewall and NAT.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

pfSense

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

Where each one falls short

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

Arch Linux

  • Installation and maintenance assume real Linux knowledge; there is no hand-holding by design
  • Rolling releases break: an update can require manual intervention, and reading the news before updating is genuinely expected
  • Unsuitable for machines that must simply keep working without attention
  • AUR packages are user-submitted and carry no security review

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

Arch Linux: Is Arch Linux free?

Yes, entirely free and open source.

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.

Arch Linux: Is Arch good for beginners?

Not as a first Linux system. It assumes you will read documentation and maintain the system yourself, which is the trade it makes deliberately.

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.

Arch Linux: What is the AUR?

The Arch User Repository, a very large collection of user-submitted build scripts. It is why almost anything is installable on Arch, and it carries no security review.

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.
