Codex CLI vs Claude Code
Compare Codex CLI and Claude Code by workflow, pricing, privacy, model support, and best use cases.
Codex CLI
Choose Codex CLI when you want OpenAI’s coding agent inside a terminal workflow with local repository access, sandboxing, approvals, MCP, skills, and scriptable automation. Choose an AI IDE or prompt-to-app builder if you need a visual development environment or a less technical product-building flow.
Claude Code
Choose Claude Code when you want a powerful Anthropic-native coding agent that can work inside your terminal, IDE, and GitHub workflow. Choose an open-source or provider-agnostic tool if local models, BYOK across many providers, or full transparency matter more than Claude-native integration.
Key Differences
Workflow
Codex CLI is OpenAI’s terminal-first coding agent for developers who want local repository editing, configurable safety controls, and access to Codex models from the command line.
Claude Code is Anthropic’s agentic coding tool for developers who want Claude to work directly inside terminals, IDEs, repositories, and CI workflows.

Privacy & Security
Codex CLI
Codex CLI runs locally and can read project files, edit code, run commands, and persist local session history under CODEX_HOME unless configured otherwise. Data sent to models depends on authentication method, selected provider, ChatGPT workspace settings, API organization settings, MCP servers, and whether local OSS mode is used. Users should avoid exposing secrets in prompts, source files, command output, or connected tools, and should configure approvals, sandboxing, ignored paths, and history persistence for sensitive repositories.
Claude Code
Claude Code may process prompts, codebase context, command output, files, tool calls, and repository metadata to provide coding assistance. Privacy and retention depend on whether the user authenticates through a Claude subscription, Anthropic API, or cloud provider deployment such as Bedrock, Vertex AI, or Foundry. Users should keep secrets out of prompts and source files, use environment variables or secret stores, and review permissions before allowing agentic actions.
