## Choose when

### Choose lagent if…

- License: lagent is Apache-2.0, langroid is MIT.
- Pricing: Available freely due to its open-source nature, but customization or enterprise support might involve additional costs..
- Tags unique to lagent: agent, llm, transformers.
- Also covers LLM Frameworks.
- When you need a streamlined approach to develop LLM-based agents with minimal overhead, lagent can be particularly advantageous due to its lightweight design.

### Choose langroid if…

- License: langroid is MIT, lagent is Apache-2.0.
- Tags unique to langroid: agents, ai, chatgpt, function-calling.
- Also covers Data & Retrieval, Inference & Serving, Model Training.
- langroid ships Docker support for self-hosted deployment.
- You need to integrate multiple agents working with large language models.

## When NOT to use lagent

- Avoid using lagent if your project necessitates integration with a broader set of tools that are not natively supported by this framework, as it offers limited out-of-the-box extensibility.
- Steer clear if you need robust scalability features right from the start. While lightweight, lagent may require additional custom work to handle more demanding scaling requirements.

## When NOT to use langroid

- You require support for a broad range of programming languages beyond Python.
- The project scope does not include multi-agent interactions or function-calling capabilities.
