Claude Code doesn’t have an official built-in sandbox environment, but the development community has created several third-party sandboxing solutions to address security concerns when using Claude Code with the --dangerously-skip-permissions flag. These community-built sandbox environments run Claude Code inside Docker containers, providing isolation between the AI agent and your main system while still allowing Claude Code to operate with full autonomy. The most notable implementations include projects like “claude-code-sandbox” and “cco” which create containerized environments where Claude Code can execute commands, edit files, and run tests without requiring permission prompts, while keeping these operations safely contained within the Docker environment.
These sandbox solutions address a key challenge with Claude Code: while the permission system provides security by asking for approval before each action, it significantly slows down workflows and interrupts the autonomous nature of the tool. The community-developed sandboxes solve this by creating isolated environments where Claude Code can run with the --dangerously-skip-permissions flag safely. These environments typically include pre-installed development tools, programming language runtimes, and common utilities, while providing features like automatic port forwarding, volume mounting for your project files, and workspace-specific configurations.
Security features in these sandbox implementations include process isolation to prevent Claude Code from affecting your host system, filesystem access control through Docker volume restrictions, and network isolation to control external connections. Some implementations also provide browser-based terminal interfaces for monitoring Claude Code’s activities and offer automatic cleanup of containers when work is complete. While these are third-party solutions rather than official Anthropic products, they have become popular among developers who want to use Claude Code’s full autonomous capabilities without compromising system security.
