What's Better in ArcBox

  • Native desktop GUI — visual container management, logs, terminal, stats
  • 10x faster startup — optimized kernel and hypervisor vs QEMU overhead
  • Better file I/O — >90% native vs 50–80% (depends on Colima's mount type)
  • Lower resource usage — <150 MB idle vs ~300 MB
  • Sandboxes — disposable dev environments
  • Automatic DNS.arcbox domains with zero configuration

What Colima Has That ArcBox Doesn't

  • Fully open source — Colima is MIT licensed end-to-end, including the CLI
  • Intel Mac support
  • K3s Kubernetes — built-in lightweight Kubernetes cluster
  • Multiple runtimes — supports containerd and Docker
  • SSH-based architecture — simple, debuggable, and scriptable
  • Linux/Windows — runs anywhere Lima runs
