OCaml is described as 'Industrial strength programming language supporting functional, imperative and object-oriented styles' and is a programming language in the development category. There are more than 25 alternatives to OCaml for a variety of platforms, including Linux, Mac, Windows, BSD and Web-based apps. The best OCaml alternative is C (programming language), which is both free and Open Source. Other great apps like OCaml are Rust, C++, Haskell and D (Programming Language).
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.
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.
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.
Haskell is an advanced purely-functional programming language. An open-source product of more than twenty years of cutting-edge research, it allows rapid development of robust, concise, correct software.
It's the same lineage but is a cousin of the ML branch. Haskell is a purely functional programming language whilst OCaml is mutli-paradigm. Haskell has lazy evaluation whilst OCaml is eagerly evaluated.
Haskell is probably one of the best alternatives!
D is a language with C-like syntax and static typing. It pragmatically combines efficiency, control, and modeling power, with safety and programmer productivity.
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.
Scala is a modern multi-paradigm programming language based on the Java Virtual Machine (JVM) designed to express common programming patterns in a concise, elegant, and type-safe way.
Functional-first language for .NET with static typing, succinct and expressive code, advanced pattern matching, object-oriented features, interop with .NET languages, async programming, type providers, cross-platform support, tooling, and immutable data.
Elixir is a dynamic, functional language designed for building scalable and maintainable applications.
Concurrent functional language with built-in support for fault tolerance, distribution, and hot swapping, designed for scalable real-time systems in telecom, banking, e-commerce, and instant messaging. Features garbage collection and dynamic typing.
Clojure is a dynamic programming language that targets the Java Virtual Machine (and the CLR ). It is designed to be a general-purpose language, combining the approachability and interactive development of a scripting language with an efficient and robust infrastructure for...

C is far more low level and not garbage collected compared to OCaml. C also uses a different syntax family (C is Algol, OCaml is ML). C is also imperative (procedural), while OCaml is declarative (functional).
