What is the project about?

Langflow is a low-code application builder designed for creating Retrieval-Augmented Generation (RAG) and multi-agent AI applications. It provides a visual interface for building and testing AI workflows.

What problem does it solve?

It simplifies the development of complex AI applications, particularly those involving RAG and multi-agent systems, by providing a visual, drag-and-drop interface and pre-built components. It reduces the need for extensive coding, making AI development more accessible. It also helps to streamline the process of building, testing, and deploying.

What are the features of the project?

• Python-based: Built on Python, making it compatible with a wide range of AI tools and libraries.
• Model/API/Database Agnostic: Works with various models, APIs, data sources, and databases.
• Visual IDE: Drag-and-drop interface for building workflows.
• Playground: Immediate testing and iteration of workflows with step-by-step control.
• Multi-agent Orchestration: Supports building and managing multi-agent conversations and retrieval.
• Cloud Service/Self-Managed: Available as a free cloud service (DataStax Langflow) or for self-managed deployment.
• API/Python Export: Publish workflows as APIs or export them as Python applications.
• Observability: Integrates with observability tools like LangSmith, LangFuse, and LangWatch.
• Customization: Allows customization of workflows or creating flows entirely using Python.
