PromptLayer

Track, version, and manage your LLM prompts — the DevOps layer for prompt engineering

Freemium
Categories: LLM, Developer Tools, Productivity, Automation
PromptLayer is a prompt management and observability platform that sits between an application and its LLM provider, logging every request and response with full metadata so teams can search, replay, and analyze their AI usage in detail. It provides a visual prompt registry where engineers and product teams collaborate on prompt templates with version history, A/B testing, and access controls, making it possible to update prompts in production without touching code or triggering a deployment. The request log captures inputs, outputs, model parameters, latency, and token costs for every API call, with filtering and export for cost analysis and quality audits. PromptLayer integrates with OpenAI, Anthropic, Azure, Cohere, and other providers by wrapping the existing SDK with a single-line change, requiring no architectural refactor. It supports evaluation pipelines, regression testing against golden datasets, and team dashboards for tracking usage trends. PromptLayer targets AI engineers, ML teams, and product builders who ship LLM-powered features and need visibility, reproducibility, and collaborative governance over the prompts driving their products.

  • Check the pricing tiers and usage limits against your expected volume so costs stay predictable.
