Zerobox

Lightweight process sandboxing with file, network, and credential controls, powered by OpenAI Codex's runtime.

Desktopfreeglobal

A lightweight, cross-platform process sandbox that runs commands with deny-by-default controls for filesystem, network, and environment access, and can inject credentials so a process can use API keys it never directly sees. It helps developers and teams run AI agent tool calls or third-party commands without exposing files, networks, or secrets, and is available as an open-source, self-hosted desktop app under a permissive license.
