Prefactor
Evaluate your AI Agents in real-time
What does Prefactor do?
Most agents pass their evals and fail in production. Prefactor is the evaluation layer that closes the gap. We score every agent run in real time, surface quality regressions and drift as they happen, and show engineering teams exactly how their agents are performing at scale. Built for the teams shipping agents to customers.
Editorial take
Prefactor stands out in developer tooling because its launch connects a focused product promise with measurable community attention. It is most useful to evaluate as a workflow tool—not as a replacement for human judgment.
