Aerokube Moon vs TestCafe

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.

TestCafe is a free, open-source test runner and end-to-end framework for web testing. Tests can be written in JavaScript or TypeScript, or recorded in a browser with TestCafe Studio. The runner works in modern browsers locally or remotely and supports concurrent runs across browsers. It can also switch between iframes and multiple browser windows to cover interactions across those contexts.

The framework includes server-side API testing tools for standalone API tests or functional tests. Other capabilities include automated waiting, authentication roles, hooks, request mocking, and debugging mode. Its CI guide lists services including GitHub Actions, GitLab, Jenkins, Azure DevOps, and CircleCI, plus BrowserStack, LambdaTest, and Sauce Labs. Installation is available through npm, with a Docker image for CI/CD pipelines. After each run, TestCafe says it deletes browser cookies, clears storage, and reloads the page; parallel runs use separate sandboxed environments. The framework is MIT-licensed. Paid Dashboard plans have test-run quotas, but those do not limit the open-source runner.
