Decision brief
LangServe offers tools to deploy and serve models using LangChain with FastAPI.
Good fit when
- When you are working in an environment where models need to be served efficiently and require the capabilities of both LangChain and FastAPI.
- If your team is proficient in Python, as LangServe leverages FastAPI for the backend which is a framework written in this language, complementing the model deployment needs with LangChain.
Avoid when
- When you prefer using frameworks or tools that are not built around Python's ecosystem and require languages like JavaScript or Java.
- If your project specifically requires a non-FastAPI backend for serving models because of specific performance criteria, constraints, or compatibility issues with FastAPI.
