PromptLayer

Version, test, and monitor every prompt and workflow.

Go to Quickstart

Prompt Registry

Give teams a dedicated place to experiment with prompts and manage versions, separate from your application code.

Evaluations

Test prompts, define quality dimensions and scoring logic, and track scores across time.

Dataset Management

Build, organize, and reuse datasets for evaluation, regression testing, and iteration.

Observability

Review inference usage, cost, and latency. Inspect individual request/response pairs alongside full AI-application traces.

Workflows

Build complex, multi-step processes by chaining prompts and logical operations together.

Features

Release Labels

Promote tested prompt versions across environments without changing application code.

AB Testing

Compare prompt variants in production and route traffic based on measured performance.

Analytics

Track usage, quality, and outcome trends as prompts and workflows evolve over time.
