Terminator is the fastest, AI-first, computer use SDK. It's designed to interact with native GUI applications on Windows using a Playwright-like API, like parsing a website. By leveraging OS-level accessibility APIs, Terminator is significantly faster and more reliable for AI agents than vision-based approaches, and can interact with background applications.
⚠️ Experimental⚠️ : Terminator is under active development. Expect bugs and breaking changes. Please report issues – we aim to fix them quickly!
| Operating System | Support Status | Key Characteristics |
|---|---|---|
| Windows | ✅ Active Focus | Full features, best performance, actively developed & documented. |
| macOS | 🟡 Partial | Core functionality available; community-driven, less documented. |
| Linux | ❌ No Support | Not currently supported. |
