#Best AI Coding Agent CLI Tools in 2025: Transform Your Terminal Into an AI Powerhouse
The command line has always been the power user's domain. In 2025, AI coding agents have invaded the terminal, turning your humble CLI into an intelligent development partner that can understand your codebase, write features, fix bugs, and even refactor entire projects—all from a simple text interface.
Unlike IDE-based AI tools, CLI agents offer unmatched flexibility, scriptability, and integration with existing developer workflows. Whether you're SSH'd into a remote server or working in a minimal environment, these tools bring AI-powered development anywhere you can open a terminal.
Let's dive into the best AI coding agent CLI tools that are reshaping how developers work in 2025.
#1. Claude Code by Anthropic
The gold standard for agentic coding in the terminal.
Claude Code is Anthropic's official CLI tool that brings the full power of Claude directly to your terminal. It's not just a chat interface—it's a complete agentic coding assistant that can explore your codebase, make changes across multiple files, run tests, and even commit code.
