JSpector
Burp Suite extension to crawl JS files in passive mode and display the results on the issues.
JSpector is a Burp Suite extension that passively crawls JavaScript files and automatically creates issues with URLs and endpoints found on the JS files.
You just have to navigate on your different targets and JSpector will start working in the background by a simple passive crawl.
A contextual menu is also available if you want to force JSpector to crawl on some targets.
