Tools to detect websites’ techs

As a web developer, most of the time I come across cool stuff (technology-wise) once I’m surfing the web and I’m always wondering, what kind of framework, library or technology has been used for their development.

I used to go with old school methods like viewing the website’s source code or inspecting elements (through dev tools) in my browser to grasp the libs and frameworks used in the web page. But you know, it takes time and thought, sometimes the code doesn’t make much sense and for some libraries about which we know almost nothing , it gets tricky to realize how things are working in the page.

In this post, I’m goint to introduce some handy tools I’ve found to detect tech stuff quickly with actually no effort.

One of my favorite tech detectors is Wappalyzer, which is actually an add-on for Chrome, Firefox and Opera browsers. You just need to simply install the add-on and that’s it! Once you’re surfing the web it’s going to show you all the detected technologies through icons in your address bar.If you click on the icons, it shows a full list of the used stuff. It can detect the server-side tech stacks/platforms, web servers, even the CMS used, and all the JavaScript libraries. If you’re wondering about any of them you can see a brief introduction to the tech in the Wappalyzer website (by clicking on tech name in the list) and go to the official website of the pertinent technology.


Builtwith is another cool  web-base tech detector I normally use. All what you need to do is to put the URL in and see the result. It shows much more details about the hosting, and server-side aspects.



Robotics and IoT through Cylon.js

In this topic, I’m going to introduce a cool JavaScript library for Robotics and IoT lovers. It’s called Cylon.

Using this library you can easily interact with other devices whether through a web browser or server-side NodeJs code.

Cylon brings the exciting robotics and the Internet of Things world to JavaScript. At this point of time it supports 50+ different platform devices plus a general purpose I/O supports with a shared set of drivers provided by cylon-gpio module.

The figures below show the most famous platforms supported by Cylon. You can find a full list of them here.

Using these 3 basic plugins, Cylon enables you to send and receive data with other devices even in a real-time streaming manner:

  • http/https (REST)
  • library
  • MQTT(an Internet of Things machine to machine connectivity protocol)

Here are some examples of using Cylon :

The code below contols an ARDrone, takes off and then lands again:

"use strict";

var Cylon = require("cylon");

  connections: {
    ardrone: { adaptor: "ardrone", port: "" }

  devices: {
    drone: { driver: "ardrone" }

  work: function(my) {
    after((15).seconds(), my.drone.stop);

Working as a software architect and developer on Network and Environment monitoring applications, I think it would be a great API gateway for the next generation of monitoring applications.  And I strongly believe that the combination of devices like smart phones, drones, sensors, robots, and so forth plus libraries like Cylon.js and cloud services like AWS IoT, would open new horizons of innovation in the new future, and makes the world much closer to what we would imagine in the Sci-Fi movies.

If Cylon is of your interest take a look into these tutorials and samples:
