Aider is an open-source terminal-based AI pair programming tool that edits code directly in your local git repository. It creates proper git commits, supports all major LLMs, and can work across multiple files simultaneously. Aider is popular with developers who prefer terminal workflows over IDE extensions.
Qoder is an agentic coding platform launched by Alibaba, with an IDE, JetBrains plugin, and CLI built around Quest Mode for delegating multi-step tasks.
