## What it is
Cuprite is a pure Ruby headless Chrome/Chromium driver for Capybara that communicates directly via the Chrome DevTools Protocol through Ferrum, with no Selenium or WebDriver dependency. It lets you run Capybara integration tests against headless Chrome with fast, reliable browser control.

## Use cases
- run capybara tests in headless chrome
- replace selenium with a faster ruby browser driver
- test javascript-heavy rails apps with capybara
- debug failing browser tests by inspecting the page
- block or whitelist network requests during tests
- run browser tests inside docker containers

## When to choose
- you use Capybara and want a Selenium-free headless Chrome driver
- you need fast, stable integration tests driven over CDP
- you run tests in CI or Docker and want simple container options

## When to avoid
- you need cross-browser testing beyond Chrome/Chromium
- your test suite depends on Selenium-specific APIs like manage calls
- you don't use Capybara or Ruby

## Facets
- artifact type: library
- maturity: active
- function: testing, e2e-testing
- domain: testing, web-development, developer-tools
- platform: ruby, browser
- tags: capybara, headless-chrome, cdp, ferrum, integration-testing, browser-driver
