## About the Tool

Promptfoo is an open-source LLM testing, red teaming, guardrails, and evaluation platform for developers building AI applications. It helps teams test prompts, compare models, evaluate RAG pipelines, scan for vulnerabilities, and add structured quality checks to AI development workflows.

The product is useful for SaaS founders and technical teams because AI apps can fail through hallucinations, prompt injection, unsafe outputs, jailbreaks, poor retrieval, and regression after small prompt changes. Promptfoo gives builders a way to test these behaviors locally, in CI/CD, or through enterprise workflows.

Promptfoo's pricing page describes a free Community version with all LLM evaluation features, all model providers and integrations, red teaming limits, vulnerability scanning, and self-hosting. Enterprise and on-premise options add collaboration, monitoring, dashboards, SSO, API access, managed cloud deployment, and support.

For FutureStack, Promptfoo belongs in Developer Tools because LLM security and testing are critical for production AI. It is best for developers, founders, and AI teams that need to test, secure, and monitor AI applications before users break them.
