The short version

  • Each has a real cost: Arch Linux installation and maintenance assume real Linux knowledge; there is no hand-holding by design; OpenWrt support is per device and per hardware revision, so a model number that worked last year may point at a different chipset this year and be unsupported.
  • They diverge on capability: Arch Linux covers Rolling release, OpenWrt covers Package manager.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

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

OpenWrt

  • Support is per device and per hardware revision, so a model number that worked last year may point at a different chipset this year and be unsupported.
  • Flashing can brick a device permanently, and on hardware without a serial console or a recovery bootloader there is no way back.
  • Devices with 4MB or 8MB of flash have been dropped from recent releases, so a lot of older hardware is stuck on unsupported versions with known vulnerabilities.
  • Hardware acceleration for NAT and routing depends on vendor drivers, and enabling traffic shaping frequently cuts a gigabit connection to a fraction of its rated throughput.
  • A sysupgrade keeps your configuration but not your installed packages, so every release upgrade is followed by reinstalling and reconfiguring add-ons by hand.

Answered from the vendors’ own pages

Arch Linux: Is Arch Linux free?

Yes, entirely free and open source.

OpenWrt: How do I know my router is supported?

Check the Table of Hardware for your exact model and revision before buying or flashing. Do not assume that a supported model number means a supported unit; manufacturers change chipsets within a model.

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.

OpenWrt: Is the OpenWrt One worth buying over a used router?

If you are evaluating OpenWrt rather than rescuing hardware you own, yes. It is supported by definition, has an unbrickable boot arrangement, and part of the price funds the project.

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.

OpenWrt: Will flashing void my warranty?

Almost always, and it may also break the ISP remote management your provider relies on for support. Keep the stock firmware image before you start.

OpenWrt: Is opkg still the package manager?

It is in the current stable releases, but development has moved towards apk, so expect package tooling and command syntax to change at the next major release.
