Are there similar or comparative tools in other languages?

I really enjoyed the latent.space podcast, thanks for the introduction!

I am reviewing the code and examples. I recall that you spoke about why you want to use XML in the podcast, and I'm still stuck on my 20 years of disliking XML. I kid, but...

Are there other tools like guardrails in other languages or using other declarative configurations? I would love to know what other options exist. Especially interested in what others in the community have evaluated and determined were insufficient compared to guardrails.

I'm specifically interested in using LLMs locally hosted, and it appears that this is useful if you are accessing an LLM over an API, like OpenAI. Is this the case?

I know there is NeMo from Nvidia: https://github.com/NVIDIA/NeMo-Guardrails
I'm looking for similar guardrails in JavaScript

With the new 0.2.0 updates, Guardrails now supports Pydantic, and it's our preferred way to define structured outputs
