Overview
Description
Stop guessing and start shipping safer AI apps. Promptfoo lets you test prompts, compare LLM models side-by-side, and automatically scan for security vulnerabilities — all from your command line or CI/CD pipeline. Used by OpenAI and Anthropic, it replaces trial-and-error with data-driven decisions so you can build AI your users can trust.
