Node.js module

Wappalyzer's software is free and open-source, permitting both personal and commercial use, allowing you to build your own custom solution to identify technologies on websites. The software is actively maintained and contributed to by a large community of developers.

There are two versions of Wappalyzer for Node.js:

The first package is complete solution for identifying technologies on websites. It includes a headless browser, a crawler and methods to extract and analyse data. Pass it a URL and get all identified technologies returned in JSON format. The module can be used a standalone command-line tool or as a dependency in JavaScript projects and is available as a Docker image.

The core package exposes a low-level API and has no dependencies. It doesn't make network requests but instead accepts data such as HTML, response headers and cookies from an external source.

Refer to the documentation linked above for installation and usage instructions and code examples.
