In their own words
Aerokube Moon
Aerokube Moon runs browser automation sessions inside a customer-managed Kubernetes or OpenShift cluster. It supports Selenium, Cypress, Playwright, and Puppeteer, with Selenium compatibility based on the W3C WebDriver specification and standard capabilities. Browser capacity depends on the cluster, while the license sets concurrent sessions. Without a license key, Moon allows up to four parallel browser sessions for unlimited use. A paid license costs $5 a month for each parallel session, scaling with the number of concurrent sessions. Aerokube recommends Helm installation. The interface lists and filters running sessions, displays browser screens, and launches sessions for manual testing. Optional features include video recording, mobile emulation, clipboard access, file transfer, and developer tools. Moon can capture network activity as HAR and upload it to S3 when configured. It exposes Prometheus metrics, including running sessions and session limits. Moon 2.x has no built-in authentication by default; ingress authentication or sidecars are described.
Web Platform Tests
Web Platform Tests is an open-source suite for checking web platform compatibility across browser implementations. Anyone can run tests through the public wpt.live deployment in an internet-enabled browser, or clone the suite for local use on Linux, macOS, or Windows. The suite includes JavaScript API, rendering, crash, WebDriver, and manual tests. Its command-line `wpt` tool runs tests in a selected browser and can produce machine-readable JSON reports and screenshots. It can also save and load expected results for continuous integration and regression tracking. Regularly collected results from a range of browsers are archived at wpt.fyi. Local setup requires Python 3.9 or later and configuration of test domains in the system hosts file. Running tests in multiple browser processes may make results less deterministic and add noise compared with the default single-process mode. The project is free and open source, and documents Windows, macOS, and Linux setup.
