## What it is
Virgil is a fast, lightweight, statically-typed systems programming language that blends functional and object-oriented paradigms. Its self-hosted compiler produces optimized standalone native executables, WebAssembly modules, or JVM JARs, and includes a built-in interpreter for quick testing.

## Use cases
- write small fast native binaries with no dependencies
- compile programs to WebAssembly modules
- build systems software that talks directly to kernels
- research on virtual machines and programming languages
- generate machine code dynamically at runtime
- run programs quickly via an interpreter during development

## When to choose
- you need lightweight, high-performance standalone executables with minimal dependencies
- you are doing VM or language implementation research
- you want a cross-compiler targeting native, JVM, and WebAssembly from one codebase
- you want algebraic data types and type parameters in a systems language

## When to avoid
- you need a mature ecosystem with extensive libraries and package management
- you require guaranteed long-term commercial support or a standard specification
- your team relies on mainstream language tooling and hiring pools
- you need a license-audited codebase, since the repository has no explicit license

## Facets
- artifact type: cli-tool
- maturity: active
- function: compiler, interpreter, programming-language, build-tool
- domain: programming-languages, compilers, developer-tools
- platform: windows, jvm, wasm, cpp
