Tool profile
Evaluation and testing toolkit for prompts, models, and LLM application behavior.
AI evaluations
Promptfoo is built for teams that want test-driven LLM development instead of prompt tinkering by feel. It focuses on evaluations, benchmarks, red teaming, and security testing for prompts, RAG systems, and LLM applications, with an open-source CLI and library at the center of the workflow.
That makes it much more engineering-oriented than most prompt tools. The value is in repeatable tests, automated attack coverage, and quality/security gates that can be wired into real development and deployment processes.
Quick fit
Editorial take
Promptfoo should be judged like a testing and security tool, not like a prompt-writing assistant. The real question is whether the team is ready to operationalize evals and red teaming as part of the software lifecycle.
