Why We Replaced Firecracker with QEMU
Hocus are building a self-hosted alternative to cloud development environment tools like GitPod and Codespaces. They moved away from Firecracker because it's optimized for short-running (AWS Lambda style) functions - which means it never releases allocated RAM or storage volume space back to the host machine unless the container is entirely restarted. It also lacks GPU support.
