Langflow
Langflow is a visual framework for building AI applications that need multi-agent orchestration or complex RAG pipelines. It was originally built by the LangChain community and later acquired by DataStax.
What it is
Langflow provides a graph-based canvas where each node is a building block - a model, a prompt, a vector store, a tool, or an agent. You connect them visually and the data flows through the graph in real-time. It's like Node-RED for AI.
Why this matters
Complex AI applications have many moving parts. Langflow makes the architecture visible:
- Real-time data visualization: see exactly what data flows between nodes
- Multi-agent orchestration: define agents, give them tools, and orchestrate their collaboration
- RAG pipeline experimentation: swap retrievers, chunking strategies, and rerankers visually
- Export as API: any flow becomes a deployable API endpoint

What runs on it
- Ollama - connect as a local LLM provider
- LangChain - underlying framework for many components
- Flowise - more opinionated, less flexible alternative

What users are saying
“Rodrigo from Langflow here! I've been itching to share this news with everyone on HN, and it’s very timely given it's happening on YC Demo Day. Best of luck to all the founders demoing today! My co-founder Gabriel and I have been building Langflow 24/7 for over a year now.”
“Gabriel from the Langflow team here. We are too! This is going to be really good for the community.”
“> Langflow will forever be free, open-source, and agnostic. Hard to make a bold claim like this when you’re no longer calling the shots. Or did you get that in contract as part of your deal?”
