What is k7?
k7 enables users to create secure virtual machine sandboxes for code execution at scale. The platform serves custom serverless deployments avoiding AWS Fargate dependency, hardened CI/CD runners avoiding Docker-in-Docker risks, and blockchain execution layers for AI decentralized applications. Users can run k7 on Kubernetes clusters using K3s, leveraging Kata Containers with Firecracker or QEMU VMMs, Longhorn for persistent storage snapshots, and k7's proprietary k7d daemon for near-instant warm VM forking through copy-on-write disk and memory cloning.
Should you self-host k7?
k7 scores 51/100 on selfhost.directory (how scoring works) and ranks #20 of 44 in Container Management. It has 824 GitHub stars.
It shipped 7 stable releases in the past year. The latest, v0.5.0, came out on 18 October 2026. New versions land roughly every 5 days.
