Codex vs Claude Code vs Gemini CLI (2026)
Blog post from Tembo
The text compares three terminal coding agents—Claude Code, Codex, and Gemini CLI—highlighting their strengths in different areas of coding workflows. Claude Code, from Anthropic, excels at implementing multi-file changes autonomously, making it ideal for refactoring and migrations. Codex, developed by OpenAI, is the best at code review with strong integration into GitHub workflows, offering flexible pricing through ChatGPT plans or per-token API usage. Gemini CLI, an open-source tool from Google, has undergone a transition to Antigravity CLI, affecting its free consumer tier but maintaining availability for enterprise users. The agents differ in their defaults and contexts, with Claude Code leaning towards implementation, Codex towards review, and Gemini offering large-context reads. The text suggests using a multi-agent approach, where tasks are routed to multiple agents to surface bugs more effectively, and highlights the potential for orchestration platforms to automate this process for teams.
