Score: 6.8/10 (Innovation: 7, Technical: 7, Documentation: 6, Utility: 7)

SideKernel is a macOS-native microVM sandbox designed to run AI coding agents like Claude Code and Codex with zero third-party dependencies, using Apple's Virtualization framework and a minimal Rust guest agent. It provides an ephemeral, secure environment with host-guest file transfer and network control, making it useful for safely testing untrusted code or running AI agents without risking the host system.

Target audience: macOS developers, AI engineers, security researchers, DevOps
