Alumnium
By Alumnium (open source; alumnium-hq). Category: Natural-language test authoring. Homepage
Alumnium's documentation describes it as an open-source library that adds a natural-language layer over Appium, Playwright and Selenium. Test steps are written as plain-language do, check and get calls inside existing test code, and an AI model the user configures interprets them. Documented surfaces are web through Selenium or Playwright and iOS and Android through Appium. It runs locally, with a GitHub Actions caching example in the docs. An MCP server has setup guides for Claude Code, Codex, Cursor and Visual Studio Code. It is MIT licensed.
