WhyLabs
After an incredible journey, we are closing this chapter of our story. WhyLabs, Inc. is discontinuing operations. It's been a privilege to define the AI Observability category together with our trailblazing customers and our extraordinary team. While WhyLabs as a company is ending, the importance of tools that enable responsible AI adoption is ever growing. We believe that the standards and technologies in this space will continue to evolve, and we are proud to have contributed to advancing the field of responsible AI operations through open source: Beyond our software, we hope the thousands of people who participated in the Robust and Responsible AI community will continue to spread best practices throughout the AI industry. We extend our sincere gratitude to everyone who made this journey possible - from our investors who supported our vision from day zero, customers who entrusted us with their AI systems, to our visionary team who made WhyLabs possible, partners who collaborated with us, and to our family and friends who supported us throughout. Together we were able to inch the world closer to a more responsible adoption of AI technology!
Promptfoo
The AI Security Platform that catches vulnerabilities in development. Trusted by 127 of the Fortune 500 and 300,000+ developers worldwide.
Based on the limited social mentions available, users view Promptfoo as a comprehensive open-source tool that combines LLM performance evaluation and security red-teaming capabilities in a single CLI interface. The tool appears to have gained significant credibility after being acquired by OpenAI in March 2026, which users seem to view as validation of its effectiveness. There's notable interest from the developer community, particularly in Korean markets, suggesting it's gaining traction among AI practitioners. However, with only social mentions and no detailed user reviews available, it's difficult to assess specific user complaints or detailed pricing sentiment.
