Our take
Pick Aider if developers who already live in git and a TTY and will paste an API key. Pick Gemini CLI if developers who want Gemini as a CLI agent and will sign in with Google or an API key. Skip Aider if people who want an IDE Agent sidebar (Cursor, Cline, Continue) and will not run aider in a repo.
