## What it is
Browser4 is an AI-native browser engine built in Kotlin for autonomous agents, intelligent data extraction, and large-scale web automation. It provides a CLI and JVM library for browsing, scraping, and crawling the web with AI-driven capabilities.

## Use cases
- scrape websites with an ai agent
- automate browser tasks at scale
- extract structured data from web pages
- crawl websites and turn html into spreadsheets
- build autonomous web-browsing agents
- control chrome headless for web automation

## When to choose
- you need AI-assisted web extraction or agentic browsing on the JVM
- you want large-scale crawling with proxy and anti-blocking support
- you prefer a Kotlin/Java library with a CLI and Maven artifacts

## When to avoid
- you need a lightweight Node.js or Python scraping tool
- you only need simple static HTTP fetching without a browser
- you require a mature ecosystem with large community support

## Facets
- artifact type: library
- maturity: active
- function: web-scraping, browser-extension, agent-framework, parser, workflow-automation, cli, http-client
- domain: artificial-intelligence, crawlers, web-development, developer-tools, large-language-models
- platform: jvm, cross-platform, cli, browser
- tags: browser-automation, ai-native-browser, web-crawling, intelligent-extraction, chrome-devtools-protocol, agentic-browser, kotlin, headless-browser, ai-agents, automation
