For developers who spend most of their day in a terminal, AI-powered CLI tools have become essential. Ollama's local model runner is ideal when privacy or latency matters, since nothing leaves your machine. OpenAI's Codex app takes a different approach — it connects to cloud models for stronger reasoning on complex coding tasks. If your workflow already revolves around GitHub, install Copilot CLI to get AI suggestions without leaving the terminal. For a broader antigravity-style toolkit that covers code generation, refactoring, and project automation in one binary, download Antigravity — it works independently of any specific hosting platform.
