FOOSPXE - Turnkey NixOS Dev Environment

What is this?

FOOSPXE is a ready-to-go NixOS development environment. Boot any x86_64 machine and get a fully configured dev box with neovim, LSP, git tools, containers, and more. No setup, no configuration, no clicking through installers.

Get FOOSPXE

Download Live ISO 3.1 GB — Full environment, works offline

Flash to USB with dd, Balena Etcher, or Rufus. Or mount directly in VirtualBox / QEMU. Boot it, explore the live environment, then run foospxe-install to write to disk.

Advanced: Network Boot

If you have iPXE or a PXE server, chainload from:

chain https://foospxe.espoautos.com/boot/boot.ipxe

Or install directly on any existing NixOS system:

nixos-install --flake github:espo/foospxe#foospxe

Easy SSH Config (optional)

Pre-configure your ISO so you can SSH in immediately. Download the config file and put it on a USB stick alongside the ISO (or on any second USB drive).
