Langflow

Langflow is an open-source framework and visual builder designed for creating and deploying large language model applications without requiring extensive coding expertise. It provides a drag-and-drop interface where developers and non-technical users can chain together LLM components, connect to external APIs, and build complex AI workflows quickly. The platform supports multiple LLM providers including OpenAI, Anthropic, and local models, making it flexible for different use cases ranging from chatbots to data processing pipelines. Langflow is particularly valuable for enterprises and startups that want to prototype and deploy custom LLM applications while maintaining control over their infrastructure and avoiding vendor lock-in. Compared to competitors like FlowiseAI, Dify, and Make (formerly Integromat), Langflow emphasizes being lightweight, community-driven, and developer-friendly while still enabling non-technical team members to participate in application building. The tool addresses a critical gap in the AI stack by providing an accessible way to go beyond simple prompt engineering into building production-ready applications that combine multiple AI models, logic gates, and external integrations. For teams building internal tools or custom AI solutions, Langflow offers the flexibility of open-source software combined with the usability of visual programming interfaces.
