VERDICT

Should I use Vyos?

Not disclosed - vyos.io

Depends. Buy it if you have network-engineering skills and want a free, scriptable router/firewall OS for cloud or bare metal. Skip it if you need a GUI, plug-and-play setup, or vendor hand-holding.

Confidence

Medium. Based on ~30 public sources: G2, Trustpilot, PeerSpot, Reddit, vendor docs, NVD, and news.

  • Homelab builders
  • ISPs and MSPs building custom routers

  • Teams without Linux or command-line skills
  • Buyers who need vendor-guaranteed, phone-support SLAs
  • Anyone unwilling to self-manage patching and upgrades

Gotchas - check before you buy

high

Free tier is rolling release only; LTS builds and official support require paid subscriptions

high

Exposed instances with static SSH keys risk MITM until CVE-2025-30095 is patched

medium

Build tools were pulled from public repos, making self-built images harder

medium

Tiny vendor (~$1.2M projected revenue); long-term support depth is thinner than big-network vendors
