Is WhyLabs worth the price?
WhyLabs shut down.
Official statement on whylabs.ai/pricing: the company is discontinuing operations. The complete platform is open sourced.
whylogs (data logging) and langkit (LLM monitoring) stay as open source. Questions go to [email protected].
This is not a buyable SKU. Best for someone who will fork the OSS, not someone who wants a hosted WhyLabs bill.
