GreyhavenHQ / greywall

Container-free, deny-by-default sandbox for AI coding agents. Kernel-enforced filesystem, network, and syscall isolation for Linux and macOS

Why this job: topics: security, ai-security, sandbox

What it does

  • Deny-by-default filesystem. only the working directory is accessible unless you allow more
  • Network isolation. all traffic blocked or routed through greyproxy with a live dashboard
  • Command blocking. dangerous commands like rm -rf / and git push --force are denied
  • Built-in agent profiles. one-command setup for Claude Code, Cursor, Codex, Aider, Goose, Gemini, OpenCode, Amp, Cline, Copilot, and more
  • Learning mode. traces filesystem access and auto-generates least-privilege profiles
