What is Promptfoo?

Promptfoo is a powerful open-source framework designed to automate the evaluation and testing of prompts for large language models (LLMs). It enables developers to systematically assess prompt quality, detect regressions, and compare performance across multiple models. With Promptfoo, you can define test cases, run evaluations, and generate detailed reports. It integrates seamlessly into CI/CD pipelines, allowing continuous testing of prompt changes. The tool supports various LLM providers and can be extended with custom metrics. Ideal for teams building AI applications, Promptfoo helps maintain high-quality prompts and reduces the risk of unexpected behavior in production.
