## What it is
Cyber is a fast, memory-safe scripting language with a VM and JIT, supporting dynamic and optional static typing plus concurrency via fibers. It ships as a CLI for running scripts and as libcyber for embedding into applications, games, and web (WASM) targets.

## Use cases
- embed a scripting language into a game engine
- run fast concurrent scripts from the command line
- script desktop applications with an embeddable VM
- run scripts in the browser via WebAssembly
- call C libraries from scripts via FFI
- learn a modern scripting language with fibers

## When to choose
- you need an embeddable, high-performance scripting runtime for apps or games
- you want lightweight concurrency with fibers in a scripting language
- you need cross-platform scripting including WASM targets

## When to avoid
- you need a mature ecosystem with extensive libraries and long-term stability
- your team requires a widely adopted language with broad tooling and hiring pool
- you need guaranteed backward compatibility across versions

## Facets
- artifact type: cli-tool
- maturity: active
- function: programming-language, interpreter, cli, concurrency
- domain: programming-languages, developer-tools, web-development
- platform: windows, wasm, cli, cross-platform
- tags: scripting-language, embeddable-vm, jit, fibers, ffi, zig, game-development, linux, macos
