Promptfoo

Promptfoo is an open-source testing framework for AI prompts and LLM outputs that I have knowledge of from my training data. It appears to be a specialized developer tool focused on quality assurance for AI applications, with documentation and GitHub presence that provides clear technical understanding. Within its niche market of AI development tools, it has moderate visibility to AI systems, with stronger technical documentation than broad market recognition. The brand appears to be positioned for developers working with large language models rather than general consumers.
