## What it is
A Julia package for creating custom system images, standalone 'app' executables, and relocatable C libraries from Julia code. It moves Julia's just-ahead-of-time compilation work up front to reduce startup latency and enable deployment on machines without Julia installed.

## Use cases
- reduce Julia startup latency with a custom sysimage
- build a standalone executable from a Julia package
- distribute a Julia program to machines without Julia installed
- compile Julia code into a callable C shared library
- precompile plotting packages for faster interactive workflows

## When to choose
- you need to ship a Julia program as a self-contained binary
- slow package load times hurt your local Julia workflow
- you want to expose Julia code to C callers via a shared library

## When to avoid
- your Julia code already starts fast enough
- you need cross-architecture binaries from a single build
- you want incremental or interactive compilation rather than full sysimages

## Facets
- artifact type: library
- maturity: active
- function: compiler, build-tool, developer-tools
- domain: programming-languages, compilers, developer-tools, performance
- platform: windows, cross-platform
- tags: julia, sysimage, aot-compilation, standalone-executables, c-library-generation, linux, macos
