Hard crust, hollow middle. Skim only.
Summary
PromptLayer is an AI observability tool for developers that provides a unified timeline and waterfall view to trace AI requests, workflows, token usage, latency, costs, and failures. It addresses the challenge of tracking complex multi-step AI systems where a single feature may span multiple prompts, models, tools, retries, and background jobs, offering visibility into which workflows drive costs, where latency occurs, which steps fail, and the true cost per user action.
