Prompt management, testing, and monitoring platform
PromptLayer is a prompt management, evaluation, and observability platform designed to let domain experts collaborate on prompts and workflows without touching the application codebase. It bridges the gap between developers and product teams building with large language models.
It provides a centralized version-controlled repository for all your model prompts and system instructions. You can track changes, compare versions side by side, and iterate on prompt wording without having to redeploy your software.
PromptLayer lets you run test inputs, evaluate outputs, and monitor production request volumes in real time. This complete visibility into token usage, latency, and model responses helps teams catch regressions before they impact users.
PromptLayer is for engineering and product teams building AI applications who want to decouple prompt engineering from code. It enables non-technical domain experts to refine prompts and run evaluations safely in a shared environment.
