qwen-code
An open-source AI coding agent that lives in your terminal.
A terminal-based AI coding assistant that helps you understand, refactor, and generate code by connecting to Qwen or other AI models.
Qwen Code is an open-source AI coding assistant that runs directly in your terminal, similar in concept to Claude Code. It is built and maintained by Alibaba's Qwen team and is optimized to work with the Qwen series of AI models, though it also supports models from OpenAI, Anthropic, and Google.
The core use case is helping developers work with code from the command line. You can ask it to explain what a codebase does, describe its structure, refactor functions, generate unit tests, or automate repetitive coding tasks. It operates as an agentic tool, meaning it can take multi-step actions — reading files, making changes, and iterating — rather than just answering single questions.
It connects to AI models through several authentication paths: an API key from Alibaba Cloud's Model Studio, a fixed-fee Coding Plan subscription, or API keys from other compatible providers like OpenRouter or Fireworks AI. The tool is configured by editing a JSON settings file, where you declare which models to use and supply your API keys. Optional integrations exist for VS Code, Zed, and JetBrains IDEs for developers who want to stay in their editor.
A developer who works primarily in the terminal and wants an AI assistant to help with understanding and modifying codebases would use Qwen Code. It is particularly relevant for users in China or working with Alibaba Cloud services, where Qwen models are natively supported. The tool is written in TypeScript and requires Node.js 20 or later.
Where it fits
- Ask an AI assistant in your terminal to explain what a codebase does and how it's structured.
- Refactor functions or generate unit tests for existing code by describing what you want.
- Automate repetitive coding tasks like adding error handling or updating API calls across files.
