About PromptLayer
PromptLayer is a prompt management, evaluation, and observability platform built for AI engineering teams. It allows users to visually edit, version, test, and deploy prompts without waiting for application redeploys. The system provides agent observability by linking production traces to prompt versions, inspecting failures, and tracking cost, latency, and token usage. Teams can also run dataset-backed tests, human reviews, and automated graders before prompt or workflow updates reach production.
