Best for: Developers building multi-agent LLM applications

Visit Langroid

Langroid is an open-source framework built around multi-agent programming. Instead of one large prompt, you design several agents that each handle part of a job and pass work between them, which can make LLM applications easier to organise.

The project is free on GitHub and has a sizeable community of stars and forks. It suits developers who want a structured, code-based way to build with language models.
