Alumnium

Alumnium is an open-source end-to-end testing tool that lets tests be written as plain-language steps, through an MCP server for coding agents or Java, Python and TypeScript clients for existing suites. It builds on Selenium, Playwright and Appium rather than replacing them, keeps browser and mobile detail out of the agent's context, and is designed to work with smaller, cheaper models. It suits QA engineers and agent-heavy teams testing web, iOS and Android apps who want tests that express intent.
