1. Spring Initializr has evolved since 2013 from a single Groovy file to a full featured web application that generates over 1 million Spring Boot projects per year. 2. The top 3 countries that use Spring Initializr are India, US, and China. Most users access it through the web interface, with some also using IDE plugins. 3. Under the hood, Spring Initializr uses a project generator powered by a project description and generation context to produce customized Spring Boot projects based on user selections. It also supports contributions from third parties to customize the project generation.
