Show HN: Safe and lightweight VMs for Coding agents

Category: devtools

Tags: virtualization, coding-agents, worktrees, isolation, vm, claude-code

Score: 7.0/10 (Innovation: 7, Technical: 8, Documentation: 7, Utility: 6)

safeagent provides lightweight Linux VMs per git worktree so parallel coding agents like Claude Code can run without port, database, or filesystem collisions. It auto-detects services (Postgres, Valkey, Temporal) from project files, boots Alpine/Wolfi VMs in about half a second on Apple's Virtualization framework, and forwards ports via gVisor user-mode networking. The tight Claude Code hook integration and zero-config service detection make it an unusually polished approach to agent isolation.

Target audience: backend developers, AI coding agent users, devops engineers
