What are Aider and OpenCode?
Aider
Aider is a command-line AI pair-programming tool that edits code in your local git repository through natural language. It works with many LLMs, including local ones, and automatically commits sensible changes.
- Terminal-based pair programming
- Git-aware edits
- Repository map context
- Works with local models
OpenCode
OpenCode is an open source AI coding agent designed to enhance your development workflow across terminal, IDE, and desktop environments. Use it to chat about code, generate changes, and execute sophisticated multi-session workflows across your projects. Key features include support for multiple AI model providers (including Claude, GPT-4, and local models), intelligent context-aware code suggestions via LSP integration, and the ability to perform complex refactoring tasks. OpenCode can help you write new features, debug issues, refactor code, and explain complex codebases in natural language. .
- Terminal-first coding agent
- Provider-agnostic model support
- LSP-aware code context
- Multi-session parallel agents
