Roc is a fast, friendly, functional programming language implemented in Zig, with a compiler toolchain that builds to machine code or WebAssembly. The project is a work in progress and has not yet reached a 0.1 release, though it offers a compiler CLI, standard library, tutorial, and examples.

Use cases

• learn a functional programming language
• compile fast native binaries from a friendly language
• build webassembly apps from a functional language
• try a single-paradigm functional language with simple primitives
• contribute to an open-source compiler written in zig

When to choose

• you want to experiment with a modern functional language that compiles to machine code or wasm
• you value fast build and run times with a friendly toolset
• you want to contribute to an early-stage language project

When to avoid

• you need a stable, production-ready language for critical projects
• you require a 1.0 release with long-term stability guarantees
• you need broad ecosystem libraries and mature tooling today
