Rust is a multi-paradigm, general-purpose programming language that emphasizes performance, type safety, and concurrency. It enforces memory safety—meaning that all references point to valid memory—without a garbage collector.

Zig is described as 'Open-source language emphasizing robustness, optimality, and clarity, integrates direct C library support, build system, modern error handling, and cross-compiling' and is a programming language in the development category. There are more than 10 alternatives to Zig for a variety of platforms, including Linux, Mac, Windows, BSD and Self-Hosted apps. The best Zig alternative is Rust, which is both free and Open Source. Other great apps like Zig are C (programming language), C++, V (programming language) and GDScript.

C is a general-purpose programming language. It was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted CPUs.

C++ is a statically typed, free-form, multi-paradigm, compiled, general-purpose, powerful programming language. It is regarded as an intermediate-level language, as it comprises a combination of both high-level and low-level language features.

V is a statically typed compiled programming language designed for building maintainable software.

GDScript is a high-level, dynamically typed programming language used to create content. It uses a syntax similar to Python.

Wolfram Language is a symbolic language, deliberately designed with the breadth and unity needed to develop powerful programs quickly. By integrating high-level forms—like Image, GeoPolygon or Molecule—along with advanced superfunctions—such as ImageIdentify or...

HolyC is very similar to regular C, so it's a very simple but powerful language. It was used to make all of TempleOS, so it definitely works to make programs.

Hare is a systems programming language designed to be simple, stable, and robust. Hare uses a static type system, manual memory management, and a minimal runtime. It is well-suited to writing operating systems, system tools, compilers, networking software, and other low-level...
Object Pascal is a multi-paradigm, object-oriented, component-based general purpose programming language.
Mussel is an interpreted programming language written in Rust. It was designed as a simple and flexible language with a focus on easy-to-read syntax and powerful expression evaluation. Mussel supports basic data types, variable bindings, functions, closures, control flow...
The Odin programming language is fast, concise, readable, pragmatic and open sourced. It is designed with the intent of replacing C with the following goals:
Zig uses manual memory management while Rust uses the borrow checker and RAII memory management.
