What is K6?

k6 is an open-source load testing tool for testing the performance and reliability of web applications and services. It allows you to script tests in JavaScript to simulate user traffic and monitor how your system responds under different loads.

Some key features of k6 include:

Ability to simulate thousands of virtual users from a single computer
Scripts written in JavaScript for flexibility
Metrics like response times, requests per second, and custom metrics
Checks like response status codes, response content, and custom checks
Thresholds for defining pass/fail criteria
Cloud execution and CI/CD integration

k6 is designed to provide meaningful and actionable load testing results to help identify performance issues before they impact real users. Its simple scripting makes it easy to get started for those familiar with JavaScript. Advanced features like thresholds and checks help provide deeper insight.

Overall, k6 aims to make scalable and realistic load testing easy and accessible to web developers and engineers for building reliable and high-performance web applications.
