Open-source visual builder for agents and RAG flows.
Category: No-Code Builders · Type: Visual agent/flow builder · Website: https://www.langflow.org
Overview
Langflow provides a drag-and-drop canvas for assembling LLM pipelines and agents from components, exporting to Python/API. The open-source project (github.com/langflow-ai/langflow) is actively maintained; its original steward DataStax was acquired by IBM in 2025, and the DataStax-hosted Langflow cloud was deprecated in early 2026, so it is best treated as a community/IBM-backed open-source project rather than a hosted DataStax product.
Key Features
- Drag-and-drop flow canvas
- Built on LangChain components
- Export flows to API/Python
- Open source, self-hostable
Role in the Agentic AI Stack
A visual front-end to the LangChain ecosystem, overlapping with Dify for rapid agent prototyping.
