## What it is
Theos is a cross-platform, Make-based build system for creating iOS, macOS, Linux, and Windows programs, originally built for jailbroken iOS tweak development. It includes tooling like the Logos preprocessor and NIC project templates to simplify building and deploying software from the command line.

## Use cases
- build jailbreak tweaks for iOS
- compile iOS software without Xcode
- create cross-platform command-line programs
- develop Logos hooks for iOS apps
- package deb files for jailbroken devices
- build macOS or Linux binaries with a unified build system

## When to choose
- you are developing tweaks or software for jailbroken iOS devices
- you want a Make-based build system that runs on macOS, Linux, or Windows
- you need Logos syntax and project templates for hook development

## When to avoid
- you are building standard App Store iOS apps, where Xcode is the supported toolchain
- you need a non-Make-based modern build system with IDE integration

## Facets
- artifact type: framework
- maturity: active
- function: build-tool, cli, developer-tools
- domain: developer-tools, mobile-development, cross-platform
- platform: windows, cli
- tags: jailbreak-development, makefile, logos, tweak-development, ios-tweaks, macos, linux, ios
