Codex CLI vs Gemini CLI: which should you use?

Codex CLI on the left and Gemini CLI on the right, each marked at its release date on our ruler.

Our pick: Pick Codex CLI for people who already use Codex and repeat the same setup prompts (presets save the typing); pick Gemini CLI for organizations on Gemini Code Assist Standard or Enterprise (Google says their access is unchanged). No overall winner: we have not benchmarked them against each other. Updated (America/Chicago).

Codex CLI

OpenAI · 0.164.0

Tested (smoke test)

A quality-of-life release: worth updating if you re-type the same prompts or switch models a lot, not a reason to switch tools.

Gemini CLI

Google · v0.65.0

Reported

Skip it as a new starter on a consumer plan; keep it only if you are on an enterprise license or a paid API key.

Pick Codex CLI if

  • People who already use Codex and repeat the same setup prompts (presets save the typing)
  • Teams that connect Codex to enterprise MCP servers and want fewer sign-in hurdles
  • Anyone who wants an open-source (Apache-2.0) agent they can run from a terminal

Skip Codex CLI if

  • You are happy with another coding agent; nothing here changes the core capability
  • You need the image preview feature but your terminal does not support Kitty or Sixel graphics

Pick Gemini CLI if

  • Organizations on Gemini Code Assist Standard or Enterprise (Google says their access is unchanged)

  • Developers who want an open-source Apache-2.0 terminal agent they can read and extend

Skip Gemini CLI if

  • You are on a Google AI Pro/Ultra plan or the free individual tier: Google says Gemini CLI stopped serving those requests on June 18, 2026
  • You want the best coding experience with the latest Gemini models: the README itself points to Antigravity CLI

Pros and cons

Codex CLI

Pros

  • Open source under Apache-2.0 (per the GitHub repository metadata)
  • Installs with a one-line script, npm or Homebrew
  • Frequent releases with detailed changelogs
  • Credential masking and sandbox hardening continue to improve

Cons

  • Release notes do not explain how to use several new features; expect to read the in-app help
  • Image previews need a Kitty- or Sixel-capable terminal
  • Alpha builds ship almost daily, so make sure you install a stable tag
  • Our test confirmed the install and sandboxed command execution only; with a small local model, plain-language edits were unreliable, and the new presets were not tested

Gemini CLI

Pros

  • Open source under Apache-2.0
  • Weekly releases and a fast-moving issue tracker
  • Enterprise access unchanged per Google

Cons

  • Not available on consumer plans since June 18, 2026 (per Google)
  • README says it is not optimized for the latest Gemini models
  • This release is mostly bug fixes
