Greywall

Container-free, deny-by-default sandbox that restricts filesystem, network, and syscall access for AI coding agents.

Desktopfreeglobal

Greywall is a container-free sandbox for AI coding agents on Linux and macOS that restricts filesystem access, network connections, and system calls to only what's explicitly allowed, so agents like Claude Code or Cursor can't reach secrets or files outside the working directory. A complementary observability mode instead logs what an agent actually does on a live dashboard, and a learning mode can auto-generate a least-privilege config from that trace.
