Moderniin

Moderniin is a general-purpose programming language designed for safety, performance, and developer productivity. It aims to blend the readability of Python and Kotlin with the memory-safety and concurrency features found in Rust. The language compiles to native code and to WebAssembly, enabling deployment on desktops, servers, and the web. Moderniin uses a strong static type system with type inference, allowing concise code without sacrificing safety. Its memory model emphasizes predictable resource management, using ownership-like semantics combined with optional reference counting to support safe concurrency and avoid data races.

Syntax is lightweight and expressive, featuring pattern matching, algebraic data types, generic programming, and a modular package system. Error handling relies on explicit result types and the possibility of recoverable errors, rather than unchecked exceptions, to support robust software design. The standard library covers systems programming, networking, I/O, and data processing, with emphasis on cross-platform compatibility and performance.

The project is open-source, with ongoing development by a community-driven foundation and multiple contributing teams. Adoption has grown in startups, research labs, and educational settings, particularly where safety and predictable performance are valued. Criticisms include a still maturing ecosystem, relatively new tooling, and competition from more established languages in certain domains.

History: Moderniin was announced in 2021 as an experimental language and reached a stable release in 2023, with regular updates since then that expanded WebAssembly support and tooling for debugging and profiling.
