Langchain Alternatives You Can Use to Build AI and Agentic Workflows

Building AI and agentic workflows is at the core of modern AI development in 2025. And LangChain has been the go-to framework for creating AI applications for a while now. But some developers are seeking alternatives that offer more flexibility, simplicity, and cost-effectiveness.

While LangChain has enabled rapid development of LLM-powered apps with tools for chaining, agents, and memory, its heavy abstraction, complex debugging, and difficulty with real-world use often make it more suited for prototyping than production-level applications.

In this article, we’ll explore some powerful LangChain alternatives you can try out that’ll help you build effective AI and agentic workflows. I’ll go through each one’s key features and best use cases so you can get a good idea of how it might help you.
