Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
Zen
Bridges multiple AI models and CLIs, enabling orchestrated workflows across Claude Code, Gemini CLI, Codex CLI, and other AI development tools.
LLM Sandbox
Securely run LLM-generated code in isolated containers across 7 languages and 3 container backends.
How to run each
Zen As a local MCP server: Docker image
claude mcp add --env "GEMINI_API_KEY=<YOUR_GEMINI_API_KEY>" --env "OPENAI_API_KEY=<YOUR_OPENAI_API_KEY>" --env "OPENROUTER_API_KEY=<YOUR_OPENROUTER_API_KEY>" --env "XAI_API_KEY=<YOUR_XAI_API_KEY>" --transport stdio zen -- docker run -i --rm -e GEMINI_API_KEY -e OPENAI_API_KEY -e OPENROUTER_API_KEY -e XAI_API_KEY mcp/zenRequires: GEMINI_API_KEY (secret), OPENAI_API_KEY (secret), OPENROUTER_API_KEY (secret), XAI_API_KEY (secret)
LLM Sandbox As a local MCP server: PyPI package
claude mcp add --transport stdio llm-sandbox -- uvx llm-sandboxCommands built only from what the marketplaces declare; the full set for every client is on each card.
Tools each declares
The marketplaces of LLM Sandbox publish no list of tools, so we do not compare tools.
Settings each asks for
Only Zen asks for
GEMINI_API_KEY (secret)OPENAI_API_KEY (secret)OPENROUTER_API_KEY (secret)XAI_API_KEY (secret)
Only LLM Sandbox asks for
BACKENDCOMMIT_CONTAINERDOCKER_HOSTKEEP_TEMPLATEKUBECONFIGNAMESPACESANDBOX_CAP_DROPSANDBOX_CPUSSANDBOX_MEMORYSANDBOX_NETWORK_MODESANDBOX_READ_ONLYSANDBOX_SECURITY_OPT
Settings as each marketplace publishes them. Asking for fewer is not better in itself.
