PromptLayer

PromptLayer is the first platform built for prompt engineers, helping teams track, manage, and share their LLM requests.

PromptLayer serves as an observability and management platform for developers building applications using Large Language Models (LLMs). It acts as a middleware between an application and LLM providers like OpenAI, Anthropic, and Google, capturing and logging every API request. This allows teams to maintain a complete history of their model interactions, which can be searched, filtered, and analyzed to debug issues, track costs, and monitor performance. Designed for prompt engineers and AI developers, PromptLayer provides a central registry for managing and version-controlling prompts. Users can iterate on prompt templates, compare different versions, and evaluate their effectiveness using custom datasets. By grouping requests into sessions, it offers a clear view of conversational context, simplifying the process of refining user experiences powered by AI. It is an essential tool for moving from development to production with LLM-based features.
