Is WhyLabs worth the price?

40/100

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 transition@whylabs.ai.

This is not a buyable SKU. Best for someone who will fork the OSS, not someone who wants a hosted WhyLabs bill.
