What is Promptfoo?

Red teaming and vulnerability tests in your CI/CD.

Who is Promptfoo best for?

Promptfoo is best for developers and security teams who need to test LLM apps and agents for prompt injection and data leaks.

  • Red teaming AI agents and RAG apps

    It generates attacks tailored to your app, including prompt injections, jailbreaks, PII leaks and unsafe tool use by agents.

  • Security checks in CI/CD

    Scans run in GitHub, GitLab or Jenkins pipelines and report findings with fix steps inside pull requests.

  • Comparing prompts and models

    You write test cases in YAML and compare outputs across model providers on your own machine, at no cost.

  • Companies with strict data rules

    The On-Premise plan runs on your own infrastructure with full data isolation and a dedicated runner.

How much does Promptfoo cost?

Promptfoo's open-source Community edition is free forever with up to 10,000 red-teaming probes a month, while its Enterprise and On-Premise plans are priced by quote.
