Crate nab 

MicroFetch - Ultra-minimal browser engine

Features

• HTTP Acceleration: HTTP/2 multiplexing, TLS 1.3, Brotli/Zstd compression
• Browser Fingerprinting: Realistic Chrome/Firefox/Safari profiles
• Authentication: 1Password CLI integration, cookie extraction
• JavaScript: QuickJS engine with minimal DOM (planned)

Example

use nab::AcceleratedClient;

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let client = AcceleratedClient::new()?;
    let html = client.fetch_text("https://example.com").await?;
    println!("Fetched {} bytes", html.len());
    Ok(())
}
