history

Project history and usage

cyan is the CLI entry point for pyzule-rw, an iOS app injector and modifier distributed from the pyzule-rw repository.

Project history

The README describes pyzule-rw / cyan as a rewrite of pyzule and acknowledges the original Azule project. GitHub repository metadata places the project creation in April 2024, with public release tags reaching v1.0 in September 2024 and v1.4.x by early 2025.

Adoption history

Official installation instructions focus on pipx or pip from the GitHub archive and state support for Linux, macOS, WSL, and jailbroken iOS on x86_64 and arm64/aarch64. Its Homebrew packaging makes the tool visible to macOS users who want a package-manager install rather than a direct pipx command.

How it is used

cyan is used to modify IPA, TIPA, or app bundles: it can inject debs, dylibs, frameworks, bundles, and app extensions, alter app metadata such as name and bundle identifier, change icons, add entitlements, and generate shareable .cyan files through the bundled cgen command.

Why package nerds care

For package people, cyan is a small modern example of a Python CLI whose upstream prefers direct archive installation but is also wrapped by Homebrew and other package sets for repeatable local tooling.

Timeline

2024: Repository created and initial work began.
2024: v1.0 release published.
2025: v1.4.x releases continued the public release line.
