// about Langflow
Langflow is a visual, open-source platform for building LangChain applications through a drag-and-drop canvas. Each LangChain component — LLMs, prompts, agents, tools, vector stores, document loaders — is a node that can be wired together and tested in real time. It makes complex RAG systems, multi-agent workflows, and chatbots accessible to developers without deep LangChain expertise. Langflow can be self-hosted or run in the cloud via DataStax Astra, and it exports deployable Python code from any workflow.
