A recent paper, published by the "Grupo de Sistemas y Comunicaciones" of the Universidad Rey Juan Carlos, Madrid, Spain compares different gender detection tools. The paper analyzes software development platforms and tries to find out how diversified public projects are. To determine the gender of developers, the team analyzed public projects and contributions on the Github and StackOverflow platforms. Gender-API.com showed the best result overall. Our quality claim has always been not to develop just any product, but the best on the market. We are all the more pleased when this claim is also confirmed externally.
