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.
Unedited captures over CDP, with no stealth plugins. Reproduce with examples/scrape_demos.py.

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.
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.
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 |
