Langflow
Langflow is an open-source low-code AI builder for visually creating, testing, deploying, and serving agentic AI apps, RAG workflows, MCP servers, chatbots, and LLM-powered flows.
Overview
Langflow helps teams move from AI prototypes to production by visually composing application workflows, testing them in real time, exposing flows through APIs, and connecting models, vector stores, tools, and data sources.
Core Features & Capabilities
Ideal for AI engineers, developers, agent builders, RAG developers, data teams, startup founders, product teams, AI consultants, automation teams, enterprise AI teams, chatbot builders, no-code and low-code builders, LLM app developers, and teams that want to prototype, test, customize, and deploy AI workflows faster.
- Build AI applications visually by connecting component nodes for prompts, models, tools, data stores, vector databases, and outputs
- Create agentic applications with agents, reusable components, agent tools, MCP servers, and MCP client integrations
- Prototype RAG workflows, chatbots, document analysis systems, and content generators with real-time playground testing
- Customize behavior with Python components while keeping flows understandable through a visual editor
- Serve flows through APIs, deploy Langflow yourself, containerize apps, or use cloud deployment for production workflows
Trending Use Cases
Why Developers Choose Langflow
Visit the Langflow website or documentation to install Langflow, try the quickstart, explore templates, review components, and build a first flow. Start by connecting inputs, prompts, models, tools, vector stores, and outputs in the visual editor, then test the workflow in the Playground. For production use, trigger flows through the Langflow API, deploy a Langflow server, containerize the app, or use Langflow Cloud. Teams building agent systems should review the agent and MCP docs to expose components and flows as tools or connect external MCP servers.
“Langflow turns AI application development into a visual, customizable workflow where teams can prototype, test, deploy, and extend agents and RAG systems without losing Python-level control.”
