HeadlessMode

stygian_browser::config

Enum HeadlessMode

pub enum HeadlessMode {
    New,
    Legacy,
}

Expand description

Controls which headless mode Chrome is launched in.

The new headless mode (--headless=new, available since Chromium 112) shares the same rendering pipeline as a headed Chrome window and is significantly harder to fingerprint-detect. It is the default.

Fall back to Legacy only when targeting very old Chromium builds that do not support --headless=new.

Env: STYGIAN_HEADLESS_MODE (new/legacy, default: new)

§Example

use stygian_browser::BrowserConfig;
use stygian_browser::config::HeadlessMode;
let cfg = BrowserConfig::builder()
    .headless(true)
    .headless_mode(HeadlessMode::New)
    .build();
assert_eq!(cfg.headless_mode, HeadlessMode::New);

Variants§

New

--headless=new — shares Chrome’s headed rendering pipeline. Default. Requires Chromium 112+.

Legacy

Classic --headless flag. Use only for Chromium < 112.
