If you ever come across a cool website and you wonder what technology stack they are using, you can checking their source code and use dev tool console to figure out. However, there are tools that serve this purpose. For example, Whatruns, Wappalyzer etc
Comparisons
1) Whatruns seems to provide more detailed / thorough information compared to Wappalyzer
2) You can follow some websites using Whatruns and get notified when there is a change
3) Wappalyzer provides APIs but Whatruns doesn't seem to have.
4) Wappalyzer is available via npm too but not Whatruns
5) Wappalyzer provides
bookmarklet which is a JavaScript function that you can bookmark but not Whatruns
Wappalyzer bookmark-able JavaScript which seems to download wappalyzer.js and attach it to the window. You can figure out by checking the code below.
javascript: (function() { var d = document, e = d.getElementById('wappalyzer-container') ; if ( e !== null ) { d.body.removeChild(e); } var u = 'https://www.wappalyzer.com/', t = new Date().getTime(), c = d.createElement('div'), p = d.createElement('div'), l = d.createElement('link'), s = d.createElement('script') ; c.setAttribute('id', 'wappalyzer-container'); l.setAttribute('rel', 'stylesheet'); l.setAttribute('href', u + 'css/bookmarklet.css'); d.head.appendChild(l); p.setAttribute('id', 'wappalyzer-pending'); p.setAttribute('style', 'background-image: url(' + u + 'images/spinner.gif) !important'); c.appendChild(p); s.setAttribute('src', u + 'bookmarklet/wappalyzer.js'); s.onload = function() { window.wappalyzer = new Wappalyzer(); s = d.createElement('script'); s.setAttribute('src', u + 'bookmarklet/apps.js'); s.onload = function() { s = d.createElement('script'); s.setAttribute('src', u + 'bookmarklet/driver.js'); c.appendChild(s); }; c.appendChild(s); }; c.appendChild(s); d.body.appendChild(c); })(); 6) Wappalyzer is open-source but Whatruns doesn't seem to be.
7) Both of them are available via Chrome and FireFox extensions.
