fortress v150.0.7871.114
स्टील्थ क्रोमियम इंजन जो कोड की एक लाइन बदलने पर स्क्रैपर्स और ब्राउज़र एजेंटों को ब्लॉक होने से रोकता है।
One browser engine to rule them all
Stealth Chromium engine · v3 (Chromium 153)
Fortress is a Chromium fork that stops scrapers and browser agents from getting blocked. Bot detectors flag automation by reading the browser fingerprint. Fortress corrects that fingerprint inside Chromium's C++, so the browser reads as an ordinary Chrome install. Point your existing Playwright or Puppeteer at it over CDP; nothing else in your code changes.
Headless, on datacenter IPs, with no proxies, Fortress loaded 86.4% of 92 protected sites. The next best stack (Camoufox) loaded 74.5%.
A site reads the fingerprint. Stock Chrome driven by a script fails CreepJS, BrowserScan, rebrowser and the WebGL check and is blocked; Fortress passes all four.
Real runs, fully headless
Unedited captures over CDP, with no stealth plugins. Reproduce with examples/scrape_demos.py.

Quick start
pip install tilion-fortress # or: npm install tilion-fortress
docker run --rm -p 9222:9222 tilion/fortress:latest # any OS, raw CDP on :9222
from tilion_fortress import Fortress
from playwright.sync_api import sync_playwright
with Fortress() as f: # launches the 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")
import { Fortress } from "tilion-fortress";
import { chromium } from "playwright";
const f = await Fortress.launch();
const browser = await chromium.connectOverCDP(f.cdpUrl);
const page = await browser.newPage();
await page.goto("https://browserscan.net");
The pip and npm SDKs download a prebuilt, SHA-256-verified binary (Linux x64, Windows x64). Portable tarballs, a .deb and the Windows .zip are on Releases.
Free for developers
v3 is free for developers, with no machine, session or concurrency caps. Activate once:
tilion activate # sign in with GitHub, Google or email; key saved to ~/.tilion/license.jwt
The key is checked offline and Fortress never reports usage. Without activation it still runs, on the public first-generation engine. For CI, Docker and agents, set TILION_LICENSE_KEY=<key> or run tilion activate --token <key>; one key covers a fleet. Production keys for larger organizations are at fortress.tilion.com/pricing.
The tilion CLI
| Command | What it does |
|---|---|
tilion activate | Unlock v3 with a one-click device flow (browser sign-in) |
tilion activate --headless | Same flow, prints the URL and code (SSH or remote hosts) |
tilion activate --token <jwt> | Save a key with no browser (CI, agents) |
tilion license status [--json] | Show the saved key's tier and expiry (--json for scripts) |
tilion license refresh | Re-issue the key before it expires |
tilion license logout | Remove the saved key and drop back to v1 |
tilion get [platform] | Download the build for this host. tilion get list shows all: linux-x64, arm64, armhf, x86, win-x64, mac-arm64, mac-x64 |
tilion mcp | Run the Fortress MCP server, stealth browsing as agent tools |
tilion [--port N] | Launch the engine and print the CDP endpoint |
