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.
