What is Promptfoo?
Promptfoo is prompt engineering tools from Promptfoo, based in San Francisco, United States. Open-source tool for testing, evaluating and red-teaming LLM prompts and applications.
Once an AI feature reaches production, prompts stop being text in a file and start behaving like code: they need versions, tests, evaluation against a dataset, and a way to change them without a deployment. Prompt engineering tools provide exactly that. They matter most for teams where non-engineers write the prompts and engineers own the consequences.
A free plan is available, with paid plans for growing teams.
