Best 10 to use in 2026

Qwen Code is an open source AI coding agent that lives mainly in your terminal. It is built to work best with Qwen models, especially Qwen3-Coder and newer versions like Qwen3.6, Qwen3.7, and Qwen3.8. It reads your codebase, understands what you are asking for in plain language, and then plans, writes, and checks the code for you.

Amp is an AI coding agent built by Amp Inc, a company that spun out of Sourcegraph in 2025. It helps developers write, edit, and test code by working through tasks called threads. Instead of just suggesting code, Amp can run commands, use tools, and even work on its own using remote machines called orbs.

Grok Build is xAI's terminal based coding agent that helps you plan, write, and fix code right from the command line. You describe what you want to build or fix, and it reads your codebase, makes a plan, edits files, runs commands, and tests the results.

Kimi Code is an AI coding agent and command line tool built by Moonshot AI. It helps developers explore codebases, edit multiple files, run commands, and finish programming tasks from start to finish. Instead of just suggesting a line of code, it can plan a task, use tools, and work through it step by step.

GitHub Copilot CLI brings GitHub's Copilot coding agent straight into your terminal. Instead of switching to an editor, you type a request and it can plan the work, edit files, run shell commands, and open pull requests on its own. It connects natively to GitHub, so it can read issues, work with branches, and manage pull requests without extra setup. You can pick from many AI models, including Claude, GPT, and Gemini options, and switch between them as needed. Plan mode lets you review a checklist before any changes happen, while autopilot mode moves faster with fewer stops. Every file change and command needs your approval first, so you stay in control throughout the process.

Cursor CLI is a coding agent you run right in your terminal instead of inside an editor. You type what you want in plain language, and it reads your files, plans the work, makes the edits, and runs commands with your approval.

OpenCode is a free, open source AI coding agent made for developers. It works in your terminal, as a desktop app, inside popular code editors, and through a local web interface.

Claude Code is an AI coding agent built by Anthropic that works inside your real development environment. Instead of just answering questions, it reads your codebase, plans the right steps, and takes action, editing files, running commands, and checking its own results.

Codex is an AI coding agent from OpenAI that can plan, write, test, and fix code with real autonomy. You describe a task in plain language, and Codex works through your project step by step, running commands, checking tests, and preparing changes for you to review.

Warp is a modern terminal that has grown into a full Agentic Development Environment, or ADE. It started as a fast, Rust-based terminal app and later added AI features that let you work with coding agents right from your command line. Warp lets you use its own Warp Agent or bring in other agents like Claude Code, Codex, and Gemini CLI, all inside the same terminal window. It also includes Oz, a tool for running agents locally or in the cloud, and Warp Drive, a shared space for saving workflows and notes your team can reuse. Warp is open source and works on macOS, Linux, and Windows. This lets you switch between everyday terminal work and AI coding tasks in one place.
