Alternatives to LangChain

Alternatives to LangChain are specialized frameworks designed for building AI applications with large language models, each offering distinct approaches to development and deployment. LlamaIndex focuses on indexing and retrieval for LLMs, making it a powerful tool for deep exploration of data, while Haystack is a framework by Deepset that allows developers to create search systems, question-answering applications, and conversational AI. Microsoft Semantic Kernel serves as a production-ready SDK that integrates large language models and data stores into applications, enabling the creation of product-scale GenAI solutions. Microsoft AutoGen offers an adaptable framework that can be used to build sophisticated multi-agent systems that have robust conversational AI and task-completion capabilities. CrewAI specializes in role-based multi-agent systems, and Flowise is an open-source, low-code platform for creating customized LLM applications with a drag-and-drop user interface.
