## What it is
Rue is an experimental systems programming language, implemented in Rust, that explores memory safety without garbage collection while aiming for gentler ergonomics than Rust or Zig. Its compiler emits native x86-64 and AArch64 machine code directly (no LLVM), producing static ELF and Mach-O executables.

## Use cases
- experiment with a memory-safe systems language without a garbage collector
- study a complete compiler pipeline with inspectable IRs
- compile small programs to static native binaries without LLVM
- explore ownership, borrowing, and comptime language design
- follow an open language-design and agent-assisted compiler project

## When to choose
- you want to learn from or contribute to an early-stage language design experiment
- you need a minimal native compiler toolchain without LLVM dependencies
- you are researching linear types, drop tracking, or compile-time evaluation

## When to avoid
- you need a production-ready language with a stable standard library
- your project requires mature tooling, ecosystem, or long-term support
- you need targets beyond x86-64 Linux, AArch64 Linux, or AArch64 macOS
