RZR

RZR is an open-source Android application in the Reading category for viewing source-code projects on a mobile device. It lets users download repository archives from GitHub, GitLab, or Bitbucket using the owner/repo format, then read the extracted project in an organized code-reading interface. The app is intended for people who want to inspect code while away from a desktop environment.

Repositories can be downloaded as ZIP files through the in-app Zip Manager plugin. After a ZIP file is imported, the folder and file tree browser provides access to the extracted project. The editor is read-only and uses the Monaco editor through a WebView, with syntax highlighting for more than 100 programming languages. Its editor and file-explorer behavior can be adjusted through the Plugins system, including word wrap, the minimap, line numbers, and zoom.

RZR can show an instant preview of README files and other Markdown files after the relevant capability is enabled. Plugins also support customization of the editor and file explorer, while the application itself supports English and 13 other languages. Repository archives require the INTERNET permission to download, and the supplied information states that RZR uses no tracking or analytics.

MirrorNest distributes RZR for Android by mirroring the official build directly on its own storage. The mirrored file is scanned for malware before publication, providing a catalog distribution route for this open-source reading tool. After extraction, users can browse, search, and read project code offline on their Android device.
