## What it is
Magnitude is an open-source, vision-first AI browser agent written in TypeScript that controls the browser through natural language commands. It combines high-level task execution, low-level mouse/keyboard actions, structured data extraction with Zod schemas, and a built-in test runner with visual assertions for web apps.

## Use cases
- automate repetitive browser tasks using natural language
- run AI-driven end-to-end tests on my web app
- extract structured data from web pages into a schema
- integrate between web apps that have no API
- replace flaky selenium selectors with vision-based assertions
- build my own browser agent on top of an existing framework
- scrape website data by describing what I want instead of writing selectors

## When to choose
- You need automation that works across arbitrary or changing UIs without brittle CSS selectors
- You want AI-assisted E2E testing with built-in visual verification and assertions
- You need to extract structured data (e.g. Zod-validated) from web interfaces
- You want a programmatic act/extract building block for custom agent workflows
- You must integrate web apps that lack APIs

## When to avoid
- You need deterministic, fast, low-cost automation without LLM inference overhead - plain Playwright or Selenium is cheaper and more predictable
- You operate offline or in air-gapped environments since it depends on vision AI models
- You do very high-volume scraping where per-action LLM latency and cost are prohibitive
- You need to automate native desktop or mobile applications rather than browsers
