Is langchain or MetaGPT better?

Neither is universally better. langchain is the stronger fit for Builders who want composable primitives and the broadest ecosystem of integrations for LLM applications; MetaGPT for Experimenting with role-based multi-agent collaboration for software and document generation. Use the side-by-side specs to decide by your own constraints.

Is langchain or MetaGPT free?

langchain is free to run and self-host; MetaGPT is free to run and self-host. Both are free to self-host — you only pay for the infrastructure and any model or API usage.

Which is more popular, langchain or MetaGPT?

By GitHub stars — a proxy for open-source adoption — langchain is ahead (147k vs 71k). Stars measure attention, not necessarily the better fit for you.

About MetaGPT

MetaGPT assigns different roles, such as product manager, architect, project manager and engineer, to LLM agents that collaborate on complex tasks. From a one-line requirement it produces user stories, competitive analysis, requirements, data structures, APIs and documents. The team behind it also publishes research such as AFlow and runs the commercial MGX product.
