Apache-2.0 license; lightweight VMs with container UX + VM isolation; v3.31.0 (May 19 2026)

Adoption

3 medium confidence

3.0

Established CNCF/OpenInfra-adjacent container-runtime project integrated into Kubernetes runtimeclass deployments; broad but operator-concentrated infrastructure adoption rather than a mass per-user count. No clean download/user figure verified; ~8k stars (corroborate only, not the basis). Level 3 reflects specialist infra reach.

standard implementation of lightweight VM containers; integrated runtime; 8k stars

Capability

4 high confidence

4.0

VM-grade isolation with OCI/Kubernetes compatibility and pluggable hypervisors; very strong isolation but higher cold-start than microVM/userspace frontier-definers, so 4.
