About
PromptLayer provides a visual prompt editor with versioning and deployment, and connects production traces to prompt versions with cost, latency and token tracking. It runs dataset-backed evals and human review, so non-engineers can iterate on prompts without changing the codebase.
Use cases: prompt-engineering, monitoring-observability
