Quick Setup (< 1 hour)

You can use PromptLayer to manage, test, and track your prompts and multi-step agent workflows. It provides a visual registry where non-technical team members can edit prompts without changing code. You can run regression tests across datasets, score outputs using automated graders or human review, and trace production requests. It records token counts, latency, and costs for every model call, letting you compare prompt performance across different versions. When bugs occur, you can inspect exact logs and roll back problematic changes immediately.
