magnitude
Basic Information
Magnitude is an open source, vision-first browser agent platform designed to let developers control browsers with natural language and visual understanding. It provides a library and tooling to build browser automations and agents that see interfaces, plan actions, execute mouse and keyboard interactions, extract structured data from pages, and run visual test assertions. The project includes a quickstart scaffold via npx create-magnitude-app, example scripts, and a test runner package for integrating visual tests into existing web apps and CI. Magnitude emphasizes a visually grounded LLM approach that specifies pixel coordinates rather than relying solely on DOM selectors, and it is positioned as a building block for automations, integrations between apps without APIs, data extraction pipelines, and automated visual testing workflows.
