The AI CLI space has expanded quickly. Claude Code from Anthropic brings conversational coding assistance to the terminal, Codex CLI handles code generation and agentic tasks from the command line. Most open claw setups start with a single command. If you're looking for an open-source AI assistant that runs locally, OpenClaw is one of the more capable options out there — it supports multiple model backends and works on Windows, macOS, and Linux without requiring a cloud account. The open source AI coding space has matured quickly. OpenCode gives you a terminal-native agent that works with any model backend, and GitHub Copilot CLI brings AI suggestions directly into your shell if you prefer a managed service.
