+short_description: A headless browser runs a full web engine without a visible window for automation, scraping, and server-side rendering.
+---
+Headless browsers run a complete browser engine — HTML parsing, CSS layout, JavaScript execution, and rendering — without a graphical interface. They power server-side web scraping, automated testing, screenshot generation, and agent tools that read and act on the web.
+
+Headless operation trades a visible window for the ability to run many browser instances cheaply in containers and CI pipelines, often driving them over protocols such as CDP, WebDriver, or MCP.
