Wappalyzer-puppeteer

Wappalyzer-puppeteer is a simple library built on top of Wappalyzer dataset that uncovers the technologies used on websites.

Wappalyzer uses zombie which can handle most websites, but fails on complex / large / js heavy sites.

Since puppeteer is stable and available for many years now, let's use the best of both words, a real browser and Wappalyzer's dataset.

The internal logic is rewritten from scratch, since the original Wappalyzer code has a lot of Promises, on-the-fly regex parsing.

Installation

$ npm i -g wappalyzer-puppeteer      # Globally 
$ npm i wappalyzer-puppeteer --save  # As a dependency 

There are three main dependencies for this project:

• Wappalyzer - for apps.json only
• puppeteer-cluster
• puppeteer

Run from the command line

wappalyzer [url] [options]

Options

--max-wait=ms        Wait no more than ms milliseconds for page resources to load.
--user-agent=str     Set the user agent string.

Run from a script

const { AppAnalytics, PuppeteerCluster, Cluster } = require('wappalyzer-puppeteer');
 
const url = 'https://www.wappalyzer.com';
 
const options = {
    maxWait: 5000,
    userAgent: 'Wappalyzer',
    // puppeteerClusterOptions is passed to puppeteer-cluster
    // More options here: https://github.com/thomasdondorf/puppeteer-cluster
    puppeteerClusterOptions: {
        concurrency: Cluster.CONCURRENCY_CONTEXT,
        maxConcurrency: 2,
        puppeteerOptions: {
            headless: true,
            ignoreHTTPSErrors: true
        }
    }
};
 
const appAnalytics = new AppAnalytics();
const wappalyzer = new PuppeteerCluster(appAnalytics, options);
 
// Load apps.json (you can provide your own json file as well)
appAnalytics
    .loadAppsjson()
    // start the puppeteer cluster
    .then(() => wappalyzer.startCluster())
    // queue an url and wait for the result
    .then(() => wappalyzer.analyze(url))
    // do whatever you want with the result
    .then(json => {
        process.stdout.write(`${JSON.stringify(json)}\n`);
    })
    // close the cluster
    .then(() => wappalyzer.closeCluster())
    .catch(error => {
        process.stderr.write(`${error}\n`);
        process.exit(1);
    });
