FAQ

What is Langflow used for?

Langflow simplifies app development of RAG (retrieval-augmented generation) and multi-agent AI pipelines and apps. Langflow is a visual low-code builder with prebuilt components to connect to any data source, vector database (from Astra DB to MongoDB or Pinecone) or API.

What is the difference between Langflow and LangChain?

Langflow is a framework that creates all the LangChain objects needed to go into production, but still enables full control over code in a Python-based application. Langflow is integrated with LangSmith for monitoring and observability of your AI apps and pipelines.

What is Astra DB?

Astra DB from DataStax is a serverless vector and NoSQL database and data API for building AI applications with unlimited scale, 20% more relevance than Pinecone, provides ease of use, and supports enterprise compliance and security.

Can I use Langflow with other vector databases?

Yes. Langflow is agnostic to any data source (web, documents, streaming) and vector or other databases. Langflow’s cloud service is tightly integrated with Astra DB but works with any data store.

Is it free to use Langflow’s hosted cloud service?

Yes, Langflow is free to use. Developers can create a free account and build, test and deploy Langflow applications for free.
