Evaluation & testing

Promptfoo

Open-source evaluation and red-teaming tool that generates adversarial inputs from configurable plugins, runs them against an LLM application, and grades outputs with deterministic and model-graded metrics in CI. The paid enterprise editions add RBAC and team scoping; audit logging and retention are not documented.

Ask for a demonstration

Demonstrate an end-to-end red-team scan of my deployed agent, including which plugins ran and how findings are scoped to a team.

Capabilities and evidence

Support labels reflect the supplied research. Documentation and vendor claims are not independent product tests. “Not established” means the researcher did not find support; it does not prove a capability is absent.

Documented by provider

Promptfoo documents generating a wide range of adversarial inputs via plugins covering prompt injection, jailbreaking, PII leakage from RAG context and tool-based vulnerabilities such as unauthorized data access and privilege escalation, then grading outputs with deterministic and model-graded metrics.

Limit: The guide does not quantify detection coverage or false-positive rates, and does not document capture of LLM spans or tool-call traces.

Documented by provider

Promptfoo Enterprise is a hosted SaaS edition and Promptfoo Enterprise On-Prem is self-hosted on any major cloud with a dedicated runner inside the customer network; both list RBAC and team management.

Limit: Audit logs, SSO, retention settings and compliance certifications are not stated on the enterprise page.

Source s2

Documented by provider

The red-teaming guide describes running scans continuously in CI/CD and feeding user-reported issues back into the red-team configuration on a review cadence.

Limit: No documented mechanism that blocks a release automatically; gating depends on the customer's pipeline.
