Welcome to the VyOS project, a Linux-based network operating system.
VyOS is a community fork of Vyatta, a Linux-based network operating system that provides software-based network routing, firewall, and VPN functionality.
How it's different from other router distros?
- Unified command line interface in the style of hardware routers.
- Stateful configuration system: prepare changes and commit at once or discard, view previous revisions or rollback to them, archive revisions to remote server, execute hooks at commit time...
- Image-based upgrade: keep multiple versions on the same system and revert to previous image if something went wrong.
- Not just firewall and VPN: includes routing protocols such as BGP and OSPF and complex routing policy language.
- Runs on physical and virtual platforms alike: small x86 boards, big servers, KVM, Xen, VMWare, Hyper-V...
- Completely free and open source, with documented internal APIs and build procedures.
- Community driven: patches are welcome, all code, bugs, and nightly builds are public.
Get the Software
Current stable release: VyOS 1.1.3 (Helium)
Old stable release: VyOS 1.0.5 (Hydrogen)
Which image should I use?
- 64-bit physical machines: amd64.
- Virtual platforms (KVM, Xen, VMWare, Hyper-V): amd64 or i586-virt (drivers and tools included!).
- 32-bit physical without PAE: i586.
i586 image kernel is built without PAE support so it works on older CPUs often found in small embedded boards.

You can verify the build signature against our public key.
VyOS images are hosted on multiple mirrors for better availability.
