Alternatives to Mastra

Aider
Aider is an open-source AI pair programming tool that runs in your terminal. It edits code directly in your local git repository using LLMs such as Claude, GPT-4o, DeepSeek, or local models, and commits each change with a sensible message. Its repository map keeps large codebases in context, making it a leading CLI alternative to IDE-based assistants like Cursor and GitHub Copilot.
