What is Cheerp?

Cheerp is a C++ compiler for the Web, based and integrated into the LLVM/clang infrastructure.

With Cheerp you can write Web applications in C/C++, or port existing C/C++ code to the Web. Your C++ code is fully optimized by the LLVM system and it's compiled into either WebAssembly, JavaScript, or a combination of them, and will run on any browser.

Getting Started

If you don't know where to start take a look at the build/installation instructions first, then visit the Getting Started page, or follow this basic WebAssembly tutorial.

For a more in-depth tutorial, please visit My first WebAssembly game (Tutorial).

Interfacing with the browser

Cheerp provide fully transparent and complete access to all HTML/DOM APIs and browser capabilities. See Browser side programming guide for more information.

Details on how Cheerp allows your C/C++ to interoperate with JavaScript transparently, visit the JavaScript interoperability page.
