The best Compiler alternative to C (programming language) is Zig, which is both free and Open Source. If that doesn't suit you, our users have ranked more than 50 alternatives to C (programming language) and seven of them are Compilers so hopefully you can find a suitable replacement. Other interesting Compiler alternatives to C (programming language) are Nim (programming language), Swift (programming language), V (programming language) and Crystal (programming language).
Open-source language prioritizing robustness, optimality, and clarity with built-in build system, direct C library compatibility, modern error handling, compile-time execution, generics, debug and release optimizations, cross-compiling, and strong package maintainer support.
Zig is specifically intended to replace C.
Nim is a statically typed, imperative programming language with a powerful macro system that tries to give the programmer ultimate power without compromises on runtime efficiency.
Open-source programming language for developing iOS, macOS, watchOS, tvOS, and visionOS apps, featuring safety, speed, type inference, generics, native-code compilation, protocol-oriented design, memory management, Playgrounds, package manager, and Objective-C interoperability.
V is a statically typed compiled programming language designed for building maintainable software.
V intends to be a very lightweight and fast alternative to C. It's still very young, currently on version 0.2.2, and the documentation is very sparse. Good for small projects, but not ready for important things yet
Programming language with Ruby-like syntax that compiles to efficient native code.
OCaml is an industrial strength programming language supporting functional, imperative and object-oriented styles.
