Terminator

Terminator is an open-source desktop automation tool that enables robust, programmatic control of native Windows applications (and soon macOS, Linux) by leveraging the accessibility tree rather than fragile pixel coordinates or OCR. It provides a Playwright-style SDK and a Model Context Protocol (MCP) server, allowing AI agents like Claude, Cursor, and VS Code to interact with any desktop application through structural selectors and high-level APIs. Ideal for developers automating QA/testing, RPA, and complex multi-app workflows, Terminator is MIT-licensed and prioritized for reliability over traditional tools like PyAutoGUI or AutoHotkey.
