BrowserBash

An open-source AI browser testing CLI that converts plain-English test objectives into real browser actions, eliminating the need for CSS selectors, XPath, or code. It targets software developers, QA engineers, and engineering teams who need to validate AI agent outputs or automate end-to-end tests without brittle locators. The tool runs on free local models via Ollama or free OpenRouter models, requires no API keys, and integrates with CI and MCP hosts like Claude Code and Cursor.
