Product Snapshot
Promptfoo is an open-source CLI and library for evaluating and red-teaming LLM apps. Promptfoo says it is now part of OpenAI, and it continues to maintain the open-source project for secure and reliable AI application testing.
What You Can Do With It
- Run prompt, model, and RAG evaluations from the CLI or library and review results in the web viewer.
- Build matrix-style comparisons across prompts, models, and test cases with caching, concurrency, and live reloading.
- Red-team LLM apps for prompt injection, jailbreaks, data leaks, policy violations, and insecure tool use.
- Use it locally, self-host it, or run it in CI/CD pipelines with provider integrations and custom API providers.
Why It Stands Out
Promptfoo combines local execution, red-teaming, and shareable review workflows in one open-source toolchain. It is built for developers and security teams that want structured LLM testing without moving evaluation data into a separate hosted platform by default.
Tradeoffs To Know
- The free Community plan is limited to 10k red-teaming probes per month.
- Enterprise features such as SSO, centralized dashboards, collaboration, managed cloud deployment, and API access are paid features.
- It is focused on LLM testing and security, not general-purpose project management or analytics.
