The short version

  • Each has a real cost: Debian community-only support; no official organisation provides paid support (unlike Ubuntu's Canonical); 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.
  • 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.

Debian

  • Community-only support; no official organisation provides paid support (unlike Ubuntu's Canonical)
  • Paid professional support requires hiring private consultants; no Debian-backed support tiers or SLAs
  • No official compliance certifications or hardened distributions available; organisations requiring FIPS or DISA-STIG must implement separately
  • Stable release cycle intentionally conservative, leading to older software versions compared to rolling-release distributions
  • Security support responsibility falls on community; no guaranteed response times for vulnerabilities

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.

Questions people ask

Is Debian or OpenWrt better?
Neither clearly leads. Debian starts at Free and OpenWrt at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Debian or OpenWrt?
Debian starts at Free and OpenWrt at Free.
Does Debian or OpenWrt run on more platforms?
Debian runs on Desktop, Server, Supercomputers, Embedded, Laptop, Workstation. OpenWrt runs on Routers, Access points, x86-64, ARM, MIPS, Embedded gateways.
Can I use Debian for free?
Both have a free tier, so you can try either at no cost before committing.
What is Debian best used for?
Debian is most often used for individual developers and users prioritising software freedom and community governance, organisations with in-house linux expertise maintaining their own systems, embedded systems and supercomputing installations where community support suffices, open-source projects and communities requiring a free, neutral linux foundation. Of those, individual developers and users prioritising software freedom and community governance and organisations with in-house linux expertise maintaining their own systems are not what OpenWrt is typically brought in for.
What can Debian do that OpenWrt cannot?
OpenWrt covers Package manager, LuCI web interface, Traffic shaping, VPN and DNS.

Answered from the vendors’ own pages

Debian: Is Debian free?

Yes. Debian is entirely free to download, use and modify. No licensing fees are required, and the project explicitly commits to remaining free.

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.

Debian: What support options are available for Debian?

Debian support is community-driven through IRC channels, mailing lists, user forums and direct contact with package maintainers. Organisations requiring professional support can hire private consultants listed in the Debian consultants directory.

Source
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.

Debian: How long does Debian receive security updates?

Each stable Debian release receives five years of support: three years of full maintenance plus two years of long-term support.

Source
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.
