Obscura is a headless browser engine written in Rust, purpose-built for web scraping and AI agent automation. At just 30MB of memory usage and 85ms page load times, it dramatically outperforms headless Chrome while providing built-in anti-detection features.

Created by h4ckf0r0day, Obscura has reached 14,788 GitHub stars and is designed as a drop-in replacement for headless Chrome when used with Puppeteer and Playwright. The key differentiator: it runs real JavaScript via V8 but with a fraction of the resource overhead.

This guide covers installation, CLI usage, CDP server setup, puppeteer/playwright integration, and production deployment.

What Is Obscura? #

Obscura is a headless browser engine that implements the Chrome DevTools Protocol (CDP) in Rust. Unlike headless Chrome, which is essentially a stripped-down Chrome browser, Obscura is built from the ground up for automation — not desktop browsing.
