Cheerp is an LLVM/Clang-based C/C++ compiler toolchain that compiles C and C++ code to WebAssembly and JavaScript for use in browsers and Node.js. It provides deep JavaScript interoperability (e.g. the [[cheerp::jsexport]] attribute) and custom optimizations to minimize output size and maximize performance.
Use cases
- compile c++ code to webassembly
- port a c++ library to the browser
- run legacy c/c++ applications in html5
- use c++ libraries from javascript or typescript
- build high-performance web apps in c++
- expose a c++ api to javascript
- compile c++ to both wasm and js from one codebase
When to choose
- you need to port existing C/C++ codebases or libraries to the web with minimal source changes
- you want fine-grained JavaScript/DOM interoperability from C++ without wrappers
- you want a single codebase emitting both WebAssembly and JavaScript output
- you need an Apache 2.0-licensed alternative to Emscripten with strong optimization
When to avoid
- you are writing a new web application in JavaScript/TypeScript with no C/C++ code
- you need server-side native compilation rather than browser/wasm targets
- you require a very mature LTS release and cannot use nightly builds
- your team has no C/C++ expertise and Emscripten's larger ecosystem would fit better
