What Is Promptfoo? Promptfoo 是什么？
Promptfoo is an open-source project with 22k+ GitHub stars. Test and evaluate LLM outputs and prompt quality
The project focuses on testing, prompt, evaluation use cases and is designed as a developer library or framework—you integrate it into your own application by importing it as a dependency.
Source code is available at github.com/promptfoo/promptfoo. Its 22k+ GitHub stars indicate strong real-world adoption across engineering teams globally.
Promptfoo takes an opinionated approach that works well for its target use case. A practical choice for teams that want to run this locally. Performance scales with hardware—the quality difference between running on a capable GPU vs. CPU is substantial for latency-sensitive applications.
