✨ Universal. Compiled. AI-Powered.

The Human Programming Language

Write once, run everywhere. Compile to WebAssembly, native, or JavaScript.

hello.upl

let name be "UPLim"

say "Hello" plus name

when name equals "UPLim" do

say "Welcome to the future!"

One Language. Everywhere.

Universal compilation to WebAssembly, LLVM, and JavaScript

🌍

Universal Compilation

Compile to WebAssembly for browsers, LLVM IR for native performance, or JavaScript for legacy compatibility. One codebase, any platform.

🛡️

Safe by Default

No null, no undefined, no crashes. Memory-safe and thread-safe with compiler-enforced guarantees and Result/Option types.

⚡

Extremely Fast

Always compiled, never just interpreted. Zero-cost abstractions, minimal runtime, cold start under 20ms.

💻

Simple to Use

Natural language syntax. Read code like sentences. No computer science degree required. Perfect for beginners and experts.

✨

AI-Native

Optional AI integration for advanced analysis and suggestions. Self-improving engine for language evolution. You stay in control.

🔗

Full Interoperability

FFI bridges to C, JavaScript, JVM, and .NET. Embed UPLim anywhere or call existing libraries seamlessly.
