LLMs produce non-deterministic outputs, making traditional exact-match testing ineffective. How can you verify an application response is contextually accurate when the response can vary with every request? Let's take a look at promptfoo!

Website performance directly affects the user's experience, and your business's bottom line. One way of identifying performance issues is via API-based load testing tools such as k6. API load tests tell you whether your services scale, and how quickly they respond under load, but they don’t measure the full user experience. Let's see how Google Lighthouse can help!

Load testing is crucial for ensuring your applications can handle expected load volumes. In this guide, we'll set up a complete load testing environment using k6 for testing, Prometheus for metrics collection, and Grafana for visualization—all orchestrated with Docker.
