Windows#

Most tools run on Windows with no setup. The tools that reach the network at a low level need a capture driver, and browser recording needs a runtime. You add each one only when you use the tool that needs it. The app checks the state of every prerequisite and helps you fix it from Settings, then Dependencies.

Install the Npcap driver#

On Windows, live packet capture and the faster port scans, such as SYN and FIN scans, work through the Npcap driver. The Npcap licence prevents the app from bundling the driver, so you install it yourself.

Download Npcap from npcap.com and run the installer in its default mode. Do not tick the option that restricts the driver to administrators only, because GraphDagger then cannot use it. Return to the app and check the row again. The status turns to Ready when the app detects the driver. See Capture permissions and Port scanning.

Record browser traces#

Playwright Inspector drives a real browser, so it needs three things: Node.js 18 or later, the Playwright package, and at least one browser binary. Install Node.js from nodejs.org, and install Playwright with npm install -g playwright. The browser binary is the one part the app installs for you, so you can add Chromium, Firefox, or WebKit from the Dependencies tab. See Installing browsers.

Render JavaScript while crawling#

This prerequisite is optional, and Windows usually meets it already. To render JavaScript-heavy sites during a crawl, you need a Chromium-family browser, and Windows includes Edge. Without one, the crawl still works, but you cannot render JavaScript.

See the Dependencies tab#

The Dependencies tab, where you check and fix all of the above, has its own page:

• Settings, then Dependencies: the full list of prerequisites and each row expanded with its install controls.
