Lean is an open-source programming language and proof assistant that enables correct, maintainable, and formally verified code.


C3 is a programming language that builds on the syntax and semantics of the C language, with the goal of evolving it while still retaining familiarity for C programmers.
Janet is a functional and imperative programming language. It runs on Windows, Linux, macOS, and should run on other systems with some porting. The entire language (core library, interpreter, compiler, assembler) is about 200-300 kB and should run on many constrained systems.

Raku unifies many great ideas that aren't usually found in other programming languages. While several other languages offer some of these features, none of them offer all.
Fortran (previously FORTRAN, derived from Formula Translating System) is a general-purpose, imperative programming language that is especially suited to numeric computation and scientific computing.
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...
Hack is a programming language for HHVM that interoperates seamlessly with PHP. Hack reconciles the fast development cycle of PHP with the discipline provided by static typing, while adding many features commonly found in other modern programming languages.
The programming language for writing single page applications. Mint has all the tools you need to write error free, easily readable and maintainable applications in record time.


Neko is an high-level dynamicly typed programming language. It can be used as an embedded scripting language. It has been designed to provide a common runtime for several different languages. Learning and using Neko is very easy.
