PromptLayer is a prompt management and LLM observability platform aimed at teams that iterate on prompts collaboratively, without code deploys. It provides a visual prompt registry with versioning and deployment, request logging with cost and latency tracking, and batch evaluation pipelines for regression-testing prompt changes. Non-engineers can edit and release prompts without code deploys, which is the product's distinguishing focus. A free plan with request caps is available; published paid pricing has varied across sources, so confirm current rates with the vendor.
