tilion-fortress

Install and drive the Fortress stealth Chromium engine, a recompiled Chromium that corrects its own fingerprint in C++ (canvas, WebGL, WebGPU, audio, fonts, navigator, and more) and exposes raw CDP, a drop-in for Playwright and Puppeteer. No build, no source.

pip install tilion-fortress

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

Unlock in one command

Fortress is free for developers. tilion-fortress activate runs a ten-second browser sign-in and saves your key to ~/.tilion/license.jwt, verified offline after that. Skip it and Fortress still runs on the public first-generation engine after one notice; it never blocks.

tilion-fortress activate              # or: tilion-fortress activate --headless   (SSH / remote)
tilion-fortress activate --token X    # CI / agents: save a key with no browser

Drive it

from tillion_fortress import Fortress

with Fortress() as f:                        # launches headless + a CDP endpoint
    print(f.cdp_url)                          # ws://127.0.0.1:<port>/devtools/browser/...
    from playwright.sync_api import sync_playwright
    with sync_playwright() as p:
        browser = p.chromium.connect_over_cdp(f.cdp_url)
        page = browser.new_page()
        page.goto("https://abrahamjuliot.github.io/creepjs/")

Platforms

Native prebuilt binaries are auto-fetched and SHA-256 verified for Linux x64, Linux arm64, Linux x86, Linux armhf, Windows x64, and macOS arm64. Run tilion-fortress get list to see them all, or tilion-fortress get <platform> to fetch one. Docker (docker run --rm -p 9222:9222 ...) is an option for any OS or CI.

CLI

tilion-fortress activate            # unlock the v3 engine
tilion-fortress license status      # tier and expiry
tilion-fortress license refresh     # renew before expiry
tilion-fortress get [platform]      # download a build ('tilion-fortress get list' shows all)
tilion-fortress                     # launch the engine and print the CDP endpoint

Installing the tilion framework package adds the shorter tilion command (tilion activate, tilion get, tilion mcp).
