AI Observability
WhyLabs was a category-defining AI observability platform that has discontinued commercial operations but open-sourced its complete technology stack. The company's legacy includes whylogs for privacy-preserving data logging and langkit for LLM monitoring, which remain available for teams seeking responsible AI adoption tools.

WhyLabs was a pioneering AI observability company that helped define the category of responsible AI monitoring and management. The company developed an AI Control Center that enabled teams to monitor machine learning and generative AI applications in real-time, surface potential security threats, and reduce the time-to-resolution of AI incidents while preserving data privacy. Although WhyLabs has discontinued its commercial operations, the company has made significant contributions to the AI observability field that continue to benefit the industry. The complete WhyLabs platform has been open-sourced, along with key tools including whylogs (an open standard for privacy-preserving data logging) and langkit (an open-source toolkit for monitoring and securing large language models). These resources remain available to help teams implement responsible AI practices. The company built a community of thousands of practitioners through their Robust and Responsible AI initiative, spreading best practices throughout the AI industry. WhyLabs' legacy lives on through its open-source contributions and the standards it helped establish for AI observability and responsible AI adoption.
