Obscura - Open-Source Headless Browser

It is an open-source headless browser engine specialized for web scraping and AI agent automation.

It embeds V8 to execute real JavaScript, and implements the Chrome DevTools Protocol (CDP), allowing Puppeteer/Playwright code to be reused as-is.

Key features are as follows.

• Memory usage is as low as around 30MB, compared to headless Chrome.
• Binary size is 70MB, much lighter than Chrome's 300MB+.
• Page load is around 85ms, claimed to be 5-10x shorter wait time than Chrome.
• Deployed as a single binary with no external dependencies such as Chrome, Node.js.
• The --stealth option supports hiding navigator.webdriver, spoofing native functions, and fingerprint randomization for GPU, canvas, audio, etc.
• Automatically blocks ad/analytics/telemetry trackers from 3,520 domains.
• CLI commands like obscura fetch, obscura serve, obscura scrape --concurrency 25, --eval handle single-page rendering, parallel scraping, and JS expression execution.
• Supports major CDP domains such as Target, Page, Runtime, DOM, Network, Fetch, Input, and also includes DOM-to-Markdown conversion.
• Automatically handles form submission, login, POST handling, 302 redirects, and cookie persistence.
