When I joined the k6 team in late November, the foremost question on my mind was "How does this compare to JMeter?" You see, I come from a performance testing consulting background, and in the last few years, JMeter has been far and away my tool of choice. So what am I doing on the k6 site, talking about how much I love JMeter? Well, firstly, it turns out that the k6 team is pretty open and transparent, especially about potential improvements in k6.

k6 v0.29.0 introduced xk6 and k6 extensions to the k6 community. 🎁🎉💪 You can now extend the functionality of k6 using Go-based k6 extensions and import them as JS modules in your k6 script. This feature opens the gates for anyone to use existing k6 extensions and write custom Go extensions for special requirements. Before this release, importing JavaScript libraries was the only possibility to extend k6.

v0.29.0 contained a lot of interesting features. Have a look at the release notes for details! gRPC is a light-weight open-source RPC framework. It was originally developed by Google, with 1.0 being released in August 2016. Since then, it's gained a lot of attention as well as a wide adoption. In comparison to JSON, which is transmitted as human-readable text, gRPC is binary, making it both faster to transmit and more compact.

How do you get started with the k6 open-source load testing tool? Here's a step-by-step walkthrough of installing k6 and running your very first load test. Timestamps below! Note from Nicole: I realized after this video that I was mixing `let` and `var` in this video. They have different implications on scope, and I would recommend you use `let` or `const` in your own scripts.

k6 is a developer-centric, free and open-source load testing tool built for making performance testing a productive and enjoyable experience. Using k6, you'll be able to catch performance regression and problems earlier, allowing you to build resilient systems and robust applications.
Quickly build test cases to validate the performance of your APIs or microservices. Validate that your system can handle the expected volume of traffic, and catch SLA/SLO-breaking performance regressions in CI before they reach production.
Built primarily for load testing, k6 tests can with advantage be reused for performance monitoring of your APIs and microservices in production.
Features:
- Seamless scaling to the cloud: Designed to use the same test in a local, distributed or cloud environment. It provides an unified experience for various usage.
- Built for automation: Designed for automating your performance tests. Get Pass/Fail behavior on your performance goals.
- Write tests in Javascript code: Full scripting language to write realistic load tests. Reuse modules and Javascript libraries to build and maintain your test suite.
- Multiple choices for storage: k6 can output test results to various backends and formats (Grafana, DataDog, Kafka, JSON).
