Concurrect web crawler which tries to detect used technologies

The crawler uses Wappalyzer's technology fingerprints in order to detect used technologies of a website. After finishing all the technologies are aggregated per single root URL.

Usage:

There are two command line arguments:

• urls - Comma-separated urls to crawl.
• follow-external - Specifies whether to follow external links.

Example usage: go run main.go -urls=https://google.com -follow-external=true

When you press a key the crawling stops and the aggregated technologies for the root urls and their links are saved into fingerprints.json file.
