Run weave locally and/or without wandb API key

[HarshTrivedi]

Thanks for the great work!

1. Can I store the traced LLM call logs locally in a file/directory of my choice instead of wandb servers?
2. If yes, can I also run weave without a wand API key, as everything is done locally?

If not, are you aware of any alternative library that supports tracing and saving locally?

Hey @HarshTrivedi , thanks! We might have a fully local (maybe sqlite based) version someday, but it's not a focus atm.

@andrewtruong That would be really cool!

I want to patch the portion of the weave code that submits to wandb server and, instead, make it save to local file/s. Do you think this is doable? If so, can you point me to relevant code/functions I should look at?

If you can somehow expose a hook or callback for custom logic one might want to apply before/after the LLM call, I think it could also be useful for other things outside of local/custom storage.

So wandb local would not be sufficient to use Weave locally?

What I am trying to figure out is Weave supports a local, virtual private cloud mode alike Braintrust.dev
