PromptLayer

PromptLayer is a prompt management, evaluation, and observability platform for AI engineering teams that lets non-technical domain experts—product, content, and subject-matter specialists—visually edit, version, and deploy prompts without touching code or waiting on an app redeploy. It combines a no-code prompt registry, dataset-backed and human/AI-graded evals, and production tracing that ties logs, cost, and latency back to specific prompt versions. Its core differentiator is decoupling prompt iteration from engineering releases so experts can collaborate and ship changes safely.
