Magnitude

Magnitude is an open-source, vision-first browser agent designed to enable natural language control of web browsers. It leverages vision AI to understand and interact with any interface, executing precise actions using mouse and keyboard, and intelligently extracting structured data. Magnitude also includes a built-in test runner with powerful visual assertions. It is built on a future-proof architecture that generalizes well across complex modern sites, desktop apps, and VMs, unlike traditional browser agents that rely on numbered boxes. It supports flexible abstraction levels and deterministic runs, making it suitable for automating web tasks, integrating applications without APIs, data extraction, and web app testing. The company offers enterprise features and support.
