Performance

Obscura offers superior performance compared to headless Chrome, with lower memory usage (30 MB vs. 200+ MB) and faster page loads (85 ms vs. ~500 ms).

Source: README
Stealth Mode

Stealth mode includes anti-fingerprinting features like session fingerprint randomization and tracker blocking, ensuring that scraping activities are less detectable.

Architecture

Obscura's architecture is modular, with separate crates for different functionalities such as DOM handling, network requests, and the Chrome DevTools Protocol implementation. It leverages Rust's concurrency features and embeds V8 for JavaScript execution. The project uses Cargo for dependency management and build processes.
