Build single-executable microVMs from Docker images

Bottlefire turns container images into standalone, zero-dependency Linux executables that bundle Firecracker and launch microVMs automatically.

$ curl -fL https://bottlefire.dev/run/debian:trixie | sh
root@container:/#

# Sandbox with Landlock
$ curl -fL https://bottlefire.dev/run/debian:trixie | \
  landrun --best-effort --unrestricted-network --rox /usr/bin --rox /usr/lib --ro /etc --ro /run --rw /dev/kvm --rw /dev/tty --rwx /tmp sh
root@container:/#

# Download the executable directly
$ curl -fL -o app https://images.bottlefire.dev/debian:trixie?arch=linux/amd64
$ file app
app: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, stripped
$ chmod +x ./app && ./app
root@container:/#

Bottlefire microVMs are built with our open-source CLI tool, bake. 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.
