📁 Structure

The repository is organized by framework, with each top-level folder containing examples, configuration, and a README.md for that framework. The examples range from simple agent tasks to more advanced scenarios, including multi-agent workflows, RAG (Retrieval-Augmented Generation), API integrations, support for state-of-the-art protocols such as A2A and MCP, and much more.

Main modules:

• ag2/
• agno/
• autogen/
• claude-agents-sdk/
• crewai/
• deepagents/
• google-adk/
• langchain/
• langgraph/
• llama-index/
• microsoft-agent-framework/
• openai-agents-sdk/
• pydantic-ai/
• smolagents/
• strands-agents-sdk/
• study-agents-differences/

All modules use uv for dependency management (pyproject.toml + uv.lock). Always check the README.md in each module for specific setup and usage instructions.

🚀 Getting Started

1. Choose a framework: Navigate to the relevant folder for the agent framework you want to explore.
2. Install dependencies: Run uv sync inside the framework folder to install all dependencies.
3. Configure API keys: Copy .env.example to .env and fill in your API keys.
4. Run examples: Execute files with uv run .py.

🧪 Comparison and Experiments

The study-agents-differences/ folder contains comprehensive scripts and utilities for comparing frameworks on common tasks, including RAG, API integration, and multi-agent workflows. It provides:

• Unified agent interfaces for Agno, LangGraph, LlamaIndex, OpenAI, and Pydantic-AI
• Performance benchmarks measuring response time, token usage, and tool utilization
• Detailed results and analysis comparing different agent designs and tool integrations
• Interactive Streamlit UI for real-time comparison (streamlit run agent-ui.py)

🤝 Contributing

All contributions are welcome! If you have suggestions for new examples, frameworks to add, or improvements to existing content, please open an issue or submit a pull request.

Notes

• All modules use uv for dependency management (pyproject.toml + uv.lock). Check each module's README.md for installation and usage.
• Install dependencies before running examples.
• Example .env.example files are provided where needed for API keys and settings.
