Fast-track new features and optimizations to Cheerp to deliver a measurable impact on your application.

Cheerp 2.7 is now available. Check it out! Release notes here.
is an enterprise-grade C/C++ compiler for the Web
can compile C/C++ into WebAssembly and JavaScript
open source, with dual licence (GPLv2 & commercial)
actively developed and backed by Leaning Technologies expertise
WHY CHEERP?
Expressive intefacing with JavaScript libraries and the DOM, without wrappers or any overhead.
Expose a C++ API to be called from external JavaScript libraries or interfaces, or directly from your page.
Combine fast linear memory with garbage collectible JavaScript objects, the best of both worlds.
Cheerp automatically generates both a WebAssembly module & a highly compatible JavaScript module, from one single code base.
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 in 2017 we stopped delivering any alternative native version and moved to a web-only application!
