Features

• Easy integration: Quickly set up communication between Langflow and Streamlit with minimal configuration.
• Simple deployment: Easily install and run the API with pip or poetry.
• Flexible execution: Run the full stack (Langflow + streamlit API) or just the Streamlit frontend with API backend.

Requirements

• Python 3.10 or higher
