Production ready

Tested on complex real-world codebases, for solving real problems effectively.

First class interoperability

Zero-overhead interactions with browser, DOM, WebAPIs (WebGL/WebAudio), or other libraries. Easy for the developer, and extremely efficient.

Enhanced debug

Source maps and a custom memory profiling tool are provided to improve the development cycle.

Developer friendly

Warnings are clear and guide towards solving any problem, along with extensive documentation and tutorials.

Powerful add-ons

In-browser memory profiling, filesystem emulation, OpenGL compatility layer, and several others.

WHY CHEERP?

Unique features

JavaScript interoperability

Expressive intefacing with JavaScript libraries and the DOM, without wrappers or any overhead.

Export C++ with [[cheerp::jsexport]]

Expose a C++ API to be called from external JavaScript libraries or interfaces, or directly from your page.

Combine memory models

Combine fast linear memory with garbage collectible JavaScript objects, the best of both worlds.

Maintain one code base

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!
