Aerokube Moon vs Selenium

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.

Selenium is a free suite of tools for automating web browsers, primarily to test web applications. WebDriver provides language bindings for controlling browsers locally or remotely, and is a W3C Recommendation. The main project supports.NET/C#, Ruby, Java, Python, and JavaScript. Selenium IDE is a browser add-on for recording and replaying interactions in Chrome, Firefox, and Edge. For distributed tests, Selenium Grid spreads work across machines and combinations of browsers and operating systems. Grid offers Standalone, Hub and Node, and Distributed configurations; Docker and Kubernetes deployment resources are also linked. Selenium Manager can discover, download, and cache browser releases and drivers. Documentation covers browser-specific functionality for Chrome, Edge, Firefox, Internet Explorer, and Safari, and names GitHub Actions and Jenkins as CI/CD examples. Selenium began in 2004 at ThoughtWorks in Chicago. Grid has no authentication by default, and the project advises restricting external access and placing it behind a secure network. The latest Opera driver functionality is not supported, and that driver is officially unsupported. Selenium costs nothing.
