v0.1.0

One language.
Every platform.

Prism is a modern systems programming language for native software, tooling and cross-platform development — one toolchain, one ecosystem, one binary that runs anywhere.

01 System

Engineered end to end

Every layer of the stack — compiler, runtime, UI, package manager, language server — is built as one system. Nothing is bolted on.

Native UI

PrismX renders real native widgets on every platform. No webviews, no JavaScript bridge — the interface is part of the binary.

Cross-platform

One codebase compiles to Windows, Linux, macOS, BSD, iOS, Android and the web. Write once, ship the same binary everywhere.

Toolchain driven

A single `prism` command builds, tests, formats, lints and packages your project. The compiler is a product, not an afterthought.

Memory safe

Ownership, borrow checking and safe-by-default pointers at compile time. Unsafe code exists, but you have to ask for it.

Built-in package manager

A registry, a lockfile and reproducible builds are part of the language. No third-party tooling required.

Language server

The LSP ships with the compiler: go-to-definition, rename, diagnostics and completions work identically in every editor.

Modern tooling

Signals, structured concurrency, zero-cost async and a formatter with opinions. Ergonomics without sacrificing speed.

02 Targets

Every platform, one codebase

The same project targets desktop, mobile, web and headless environments. Platform code stays where it belongs — behind the standard library.

03 Tooling

Editors are a first-class citizen

The language server gives you the same experience in every editor — whether it runs inside the compiler or inside your IDE of choice.
