k6-browser is a k6 module that supports browser automation through the Chrome Devtools Protocol (CDP). It adds browser-level APIs to interact with browsers and collect frontend performance metrics as part of your k6 tests.

As of k6 version 0.52.0, k6-browser is now bundled in k6 as a core module and usable without a separate binary or compilation step!

Special acknowledgment to the authors of Playwright and Puppeteer for their trailblazing work in this area.

Goals

Bring browser automation to the k6 testing platform while supporting core k6 features like VU executors, scenarios, metrics, checks, thresholds, logging, DNS remapping, IP blocklists, etc.
Test stability as the top priority by supporting non-flaky selectors combined with auto-waiting for actions just like Playwright.
Aim for rough API compatibility with Playwright. The reason for this is twofold: first, we don't want users to have to learn a completely new API just to use xk6-browser, and second, it opens up the possibility of using the Playwright RPC server as an optional backend for the k6 browser module should we decide to support that in the future.
Support for Chromium-compatible browsers first, and eventually Firefox and WebKit-based browsers.

Please take a look at our project roadmap for more details.
