Unlike containers, each sandbox gets its own dedicated kernel, preventing host compromise. Key features include Sandbox Kits (YAML-based configuration artifacts for customizing environments), a host-side proxy that injects credentials without exposing secrets inside the sandbox, and a standalone sbx CLI that doesn't require Docker Desktop. The post addresses common developer questions about why microVMs were chosen over containers, why Docker built its own VMM instead of using Firecracker (cross-platform macOS/Windows support), and current limitations like missing automatic port publishing. ## Full article daily.dev links to this article rather than hosting it.
