Langflow vs Prefect
Side-by-side comparison to help you choose the best tool.
Langflow
freemiumLangflow is an open-source, low-code visual builder for creating AI agents and RAG pipelines built on top of LangChain. Its drag-and-drop canvas lets developers and AI teams compose LangChain components visually - connecting LLMs, vector stores, tools, and memory - without writing boilerplate code. Langflow is popular for rapidly prototyping complex AI pipelines that can then be deployed as APIs.
Prefect
freemiumPrefect is a modern workflow orchestration platform for data and ML pipelines with Python-native task scheduling, observability, and error handling. It makes it easy to convert existing Python scripts into observable, scheduled workflows with minimal changes. Prefect provides automatic retries, caching, parameterisation, and a rich dashboard for monitoring pipeline runs.
