What the numbers say

That is about 20 times as many for OpenAI Codex CLI, though projects that squash each pull request into one commit show fewer commits for the same work, so treat the gap as a rough signal.

Gemini CLI has 107,440 GitHub stars and OpenAI Codex CLI has 129,757; stars show how many people bookmarked a project, not how many use it.
What this comparison does not tell you
These are maintenance signals only. They do not measure speed, output quality, features, documentation or how easy either tool is to run, and we have not benchmarked either tool for this page. A quiet repository can still be a good fit for a stable job, and a busy one can still break between releases. Use the numbers to decide what to check next, not which tool is better.
Each tool’s full record
How this is measured: commits on each repository’s default branch counted through the GitHub API, the last 91 days against the same 91 days a year earlier; stars, licence and archived flag from the repository; README checked daily for maintenance notices. Visitor ratings come from visitors to each tool’s page, not from EvalAITools.
