What is PromptLayer?<\/h2>\n

PromptLayer sits between your app and AI models such as OpenAI, Anthropic and Google. It logs every request and response, so you can see what your prompts are doing, how much they cost and how fast they run.<\/p>\n

Its visual prompt registry lets non-technical teammates, like product managers or domain experts, edit and test prompts without touching the codebase. Evaluations help you compare prompt versions before you ship them.<\/p>\n
