Carbon is an experimental successor language to C++ with bidirectional C++ interoperability, built on LLVM for C++-level performance. The repository contains the language design documents, compiler implementation, toolchain, and related tooling.
Use cases
- migrate a C++ codebase to a modern successor language
- explore experimental programming language design
- compile and run Carbon code with the Carbon toolchain
- evaluate C++ interoperability in a new language
- learn how language compilers and toolchains are built
- contribute to an open-source successor-to-C++ effort
When to choose
- you want to experiment with or contribute to a next-generation C++ successor language
- you need C++-level performance with gradual migration from existing C++ code
- you are researching language design, generics, or compiler toolchains
When to avoid
- you need a production-ready language for shipping software today
- you want a stable, standardized language with long-term guarantees
- a mature modern language like Rust, Go, or Swift already fits your needs
