Decision brief

Kiln is a versatile AI systems development toolkit that excels in comprehensive evaluation frameworks for agents, RAG components, and fine-tuning processes.

Good fit when

When you need extensive tools for evaluating custom AI agents
For projects requiring retriever-augmented generation with robust optimization features

Avoid when

If your project strictly requires a lightweight tool without comprehensive dataset management options
Avoid if you do not require advanced synthetic data generation capabilities
