Install and drive the Fortress stealth Chromium engine. Prebuilt binary, no source.

tilion-fortress

Drive the Fortress stealth Chromium engine with one line — no build, no Chromium source.

---

Stop getting blocked — without puppeteer-stealth. JavaScript stealth patches self-reveal: a detector checks whether a getter is native code and catches the override. Fortress compiles the fingerprint correction into Chromium's C++, so a page inspecting itself sees stock Chrome. It clears CreepJS, Sannysoft, BrowserScan, and live Cloudflare as a normal Chrome install.

Install

pip install tilion-fortress

On first use it downloads the prebuilt Fortress binary for your platform from the official GitHub Release (SHA-256 verified) and caches it. No Chromium source, no compilation.

Quick start

from tilion_fortress import Fortress
from playwright.sync_api import sync_playwright

with Fortress() as f:                                   # launches the stealth engine on a CDP endpoint
    with sync_playwright() as p:
        browser = p.chromium.connect_over_cdp(f.cdp_url)
        page = browser.new_page()
        page.goto("https://bot.sannysoft.com")
        page.screenshot(path="all-green.png")

Keep your existing Playwright / Puppeteer / CDP code — just point it at f.cdp_url. Works the same under browser-use, Crawl4AI, Stagehand, and LangChain.

Verified against live detectors

Suite	Result
CreepJS	0% headless · 0% stealth
bot.sannysoft.com	0 failed · all green · WebGL = NVIDIA RTX 3060 / ANGLE D3D11
browserscan.net	"No bots detected, could be a human"
rebrowser bot-detector	no Runtime.enable leak · webdriver=false
Cloudflare Turnstile	cleared a live challenge

Custom persona

The default persona is a coherent Windows identity. Override any surface:

Fortress(
    persona={"timezone": "America/Chicago", "languages": "en-GB,en",
             "hw_concurrency": 16, "webgl_renderer": "ANGLE (NVIDIA, RTX 3060 ...)"},
    extra_args=["--window-size=1280,800"],
)

Platform support

Linux x64 has a native prebuilt binary. On macOS / Windows the package transparently runs Fortress via the official Docker image (tilion/fortress) — Docker is the cross-OS vehicle until native Win/Mac builds ship.

Still blocked? ~90% of the time it's your IP, not your fingerprint — datacenter ranges are flagged before any page script runs. Route egress through a residential or mobile proxy and retry.
