AI agents get blocked the moment they act on the real web: sites detect the automation and shut them down. Fortress fixes that. Add it with one line of code, or drop in our MCP, and your agents pull leads, monitor prices, book, check out, and research across the web without getting blocked. It's a stealth Chromium that reads as an ordinary Chrome, so keep your Playwright or Puppeteer and nothing else changes. Open engine, BSD-3.
