What Users Say About CubeSandbox

👍 What Users Love

  • ✓Hardware isolation (dedicated guest kernel) is a real security win over Docker
  • ✓Sub-60ms start and <5MB overhead make thousands of concurrent sandboxes viable
  • ✓E2B SDK drop-in means zero-code migration for existing users
  • ✓Snapshot/rollback is a killer feature for RL training and SWE-Bench rollouts
  • ✓Apache 2.0, self-hosted, and CNCF-listed — no vendor lock-in

👎 Common Concerns

  • ⚠Self-hosting on Linux + KVM is real ops work vs. a managed service
  • ⚠Windows/macOS hosts need a Linux VM in the loop for local dev
  • ⚠No MCP server yet — integration is via the REST API/SDK only
  • ⚠New project relative to E2B, so ecosystem/tooling is thinner
  • ⚠Cluster deploy needs Terraform familiarity for anything past single-node
