Langflow

Langflow is an open-source platform for building AI applications through a visual interface. You create workflows by connecting building blocks called components. Each component performs a specific task, such as loading data, talking to an AI model, or storing information in a database.

The platform supports agents that can make decisions, use tools, and perform multiple tasks automatically. It also enables Retrieval Augmented Generation (RAG), which lets AI applications search through your documents and provide accurate answers based on your specific data.

There is no cost to use Langflow. It's completely free and open-source. You only pay for external services you connect to it, such as AI model providers like OpenAI or cloud hosting if you choose to deploy your application online.
