SlyBrowser for Python

pip install slybrowser==0.3.1

launch() accepts the authorization file plus optional profile, launch, and humanize values. No import command is required. The SDK manages release selection, verification, download, pairing, and temporary state.

from slybrowser import launch

with launch(
    "account.authorization.json",
    {
        "profile": {"locale": "en-US", "screen": {"width": 1440, "height": 900}},
        "launch": {"headless": True, "profileMode": "ephemeral", "updateKernel": True},
        "humanize": {"enabled": True, "preset": "default"},
    },
) as browser:
    browser.get("https://example.test")
    print(browser.title)

The default path uses the matched project WebDriver and never falls back to a system browser. Install slybrowser[playwright] and use launch_playwright() only when the explicit adapter is required. A persistent adapter variant is also available.

Unknown or unsupported options, failed authorization, release verification errors, and browser/driver mismatches stop the launch. Treat the authorization file as a credential: do not commit, log, or share it.

See the complete SDK user API for every field and default.
