web technology from chrome inspector. is the page written in rails, node.js, etc

Question

As the title states, how can I find out if a webpage was written in a certain framework or language for example in node.js or php, rails etc?

Answer 1

Currently I use two tools :

• Wappalyzer extensions
• BuiltWith extensions (available on more browsers)

Wappalyzer is a bit more clearer when it comes to interface, BuiltWith comes with a bit more details. I cross the results for better understanding.

Works for most sites but sometimes fails (as it can't tell me for Stackoverflow for instance).
