Alumnium

Alumnium is an open-source Python library for software and test engineers who want to write human-readable test instructions and execute them as automated web and mobile tests.

Key capabilities include:

• Natural-language test commands using simple primitives like do (actions), check (assertions), and get (data extraction) that translate into executable automation.
• Tooling integrations with Selenium, Playwright, and Appium, enabling browser and mobile testing without switching ecosystems.
• LLM provider support across Anthropic, Google Gemini, OpenAI, Meta Llama, DeepSeek, and Mistral, plus local models via Ollama.
• Reliability features such as automatic waiting and retry behavior during execution.

Pricing: Free (open-source), distributed as a PyPI package (requires Python 3+).

Notable for its high-level abstraction that supports gradual adoption in existing Python test setups, plus an optional Model Context Protocol (MCP) server that lets general-purpose AI agents (for example, Claude Code) drive web and mobile automation. It also reports 98.5% on the WebVoyager benchmark with Claude Code and Selenium.
