TrendsOverflow is a very simple website that displays the number of questions per day for the most popular programming languages from Stack Overflow.

I created this application because I wanted to compare the popularity of different languages. I tried to use Google Trends but sometimes Google mixes data from programming languages and non-programming languages. I thought that data from Stack Overflow would be more accurate than the popularity provided by Google Trends, so I decided to retrieve this information by myself. As I did not find any published website offering this information, I decided to develop this very simple application by myself.


trends graph for css, django and javascript

Download / Install:

To use, just visit the website, trendsoverflow.educalleja.es, and enter your search terms.
