## What it is
Lily is a statically-typed, interpreted programming language focused on expressiveness and type safety, implemented in C. It is designed to be embedded in applications with sandboxing support, offering classes, generics, algebraic data types, and exceptions.

## Use cases
- embed a sandboxed scripting language in a C application
- write scripts with static type safety
- learn a statically-typed scripting language
- run quick scripts from the command line
- try a language with Option and Result types built in

## When to choose
- you need an embeddable, sandboxable scripting interpreter with a C API
- you want static typing with generics and algebraic data types in a scripting language
- you want a dependency-free language built with just CMake and a C11 compiler

## When to avoid
- you need a large ecosystem of third-party packages and libraries
- you need maximum runtime performance from a compiled language
- you need a language with broad industry adoption and community support

## Facets
- artifact type: library
- maturity: active
- function: interpreter, programming-language, sdk
- domain: programming-languages, developer-tools
- platform: windows, cross-platform, cli, c
- tags: embeddable, scripting-language, statically-typed, sandboxing, type-safety, reference-counting, command-line, linux, macos
