Bottlefire turns container images into standalone, zero-dependency Linux executables that bundle Firecracker and launch microVMs automatically. They come with zero-config userspace networking, port mapping, and host-to-vm directory sharing, just like regular containers. They just work on any modern amd64/arm64 Linux platform where KVM is available, without requiring root privilege or system-level setups.
