Gemini CLI: The Ultimate Open-Source AI Terminal for Developers

Imagine a terminal that thinks with you, not just waits for commands.

Gemini CLI delivers code fixes, writes tests and generates visuals all from your shell. Want to search, summarise docs, or debug live? Done in natural language.

No context switching, no fragmented tools. One environment. One AI-fueled brain. From cluttered terminal windows to streamlined flow, this transforms dev.
