In Depth
Codex CLI
Codex CLI is OpenAI's open-source coding agent that runs directly in your terminal. Built in Rust for speed, it launches into a full-screen terminal UI where it reads your repository, makes edits, and runs commands as you iterate together. It brings the power of o3 and o4-mini into your local workflow with a conversational interface where you review every action in real time. Install via npm or Homebrew, authenticate with your ChatGPT account or API key, and you are coding. The codex-mini model is optimized specifically for low-latency code Q&A and editing. It is included with ChatGPT Plus, Pro, Business, Edu, and Enterprise plans at no additional cost. For developers who want OpenAI's models in a local terminal workflow rather than a browser, this is the tool.
Claude Code
Claude Code is a terminal-based coding agent from Anthropic. You give it a prompt, and it reads your codebase, plans changes, edits files, runs tests, and commits - all autonomously. It spawns sub-agents for parallel work, uses persistent memory (CLAUDE.md files) to remember project context between sessions, and integrates with MCP servers for external tools. I run it on the Max plan ($200/mo) and it handles everything from multi-file refactors to full feature builds. My video on Claude Code sub-agents hit 160,000 views - it's the tool my audience asks about most. The latest version uses Claude Opus 4.6 under the hood.
The Verdict
Both Codex CLI and Claude Code are strong tools in the ai coding space. The right choice depends on your workflow. Read the full review of each tool for a deeper dive, or watch the video walkthroughs to see them in action.
