About Langflow
Overview
Langflow is a low-code AI builder for agentic and RAG applications. It lets teams build and deploy AI agents and MCP servers with visual state flows instead of hand-written boilerplate code. It ships with support for all major LLMs, vector databases, and a growing library of AI tools.
Developers can run the open-source build locally with pip install or sign up for a free enterprise-grade cloud account to deploy and scale. The same Langflow experience works whether you use the open-source version or the cloud.
Key Benefits
- Build stateful AI applications with a visual drag-and-drop flow builder
- Reuse hundreds of pre-built flows and reusable components
- Customize anything with Python under the hood
- Run a single agent or a fleet of agents with all components exposed as tools
- Deploy and scale flows as APIs on a free, secure enterprise-grade cloud
- Swap and compare models, tools, and vector stores
How It Works
Start from one of hundreds of pre-built flows or build your own by dragging components onto the canvas. Connect models, vector databases, and tools, then run, share, and collaborate. When you are ready, deploy yourself with pip install or sign up for a free cloud account to expose your flow as an API.
Use Cases
- AI development teams prototype and iterate on agentic workflows visually
- RAG application developers connect models, vector stores, and data sources
- Product teams turn complex AI ideas into visual flows that non-engineers can read
- Organizations deploy and scale AI applications on an enterprise-grade cloud
- Developers customize flows with Python for limitless control
Why Choose This Product
