Our review
Gemini CLI is Google's open-source terminal coding agent: it reads and writes files, runs commands and searches the web, and a personal Google account gets a generous free quota — the fastest zero-cost way to try a terminal agent.
Stability on complex tasks still trails Claude Code, and long sessions occasionally drift. But open source, free, and backed by Gemini models — that combination makes it one of the most worthwhile installs for terminal users.
