Industry and Product Insights

The performance and size of the converted code have been always quite impressive, but in the last year, Cheerp has further dramatically improved the runtime speed, and drastically reduced the compiled size, allowing us to save on bandwidth and resources, as well as to extend our customer base. As a matter of fact, the performance is so good that […] we moved to a web-only application!
