StackOverflow annualy gives all registered users the possibility to create a good dataset which get released in raw data and processed with quite good and interesting results: https://insights.stackoverflow.com/survey
But when coming to cross year perspective and especially to an interactive salary related tool it is not very handy. So that is what this project is intended for.
We use the raw data and try not to process the data to much. Just give some filters and give developers an easy and free way to compare their salary and developement with these.
It is highly recommended to checkout the repository and run the code locally for perfomance reasons.
Here you can see a full online demo of the current master deployment. WARNING: Do not open the site with Mobile Data it will Download up to 2 GB of Data!
