About Langflow
Langflow is a visual, low-code platform for building AI agents, retrieval-augmented generation (RAG) pipelines, and multi-step AI workflows using a drag-and-drop interface. Originally created as an open-source project in 2023, Langflow was acquired by DataStax in 2024 and integrated with the Astra DB vector database platform.
The platform provides a node-based visual editor where users connect components representing LLMs, vector stores, document loaders, text splitters, embedding models, and custom Python code. Each component has configurable inputs and outputs, allowing users to build complex AI pipelines without writing infrastructure code. As of early 2026, Langflow supports connections to OpenAI, Anthropic Claude, Google Gemini, Cohere, HuggingFace models, and local LLMs via Ollama.
Langflow can be self-hosted (open-source, available on GitHub with 20,000+ stars) or used through the DataStax-hosted cloud version. The cloud version includes a free tier with limited executions, a paid tier starting at approximately $25 per month with higher limits, and enterprise pricing for teams needing dedicated infrastructure and support. The platform targets developers and technical teams building AI-powered applications who want a visual development environment rather than pure code.
