U Programming Language

About

U is a programming language that compiles to portable C, designed so both humans and LLMs write memory-safe, race-free, injection-resistant code by default without manual annotations, catching errors like null dereferences and unauthorized side effects at compile time. It also serves as a transpilation target for existing PHP and Node.js codebases: a pipeline converts an app to U, compiles it through C into a small dependency-free native binary, which the creators report runs several times faster than the original in their own benchmarks.
