blobsaver

The application provides a graphical interface and a command‑line tool that continuously retrieve and store SHSH blobs for iOS devices. It runs in the background, automatically fetching blobs for both standard and jailbroken devices, and records associated data such as the apnonce, generator, and ECID. Users can manage an unlimited number of devices and obtain blobs for beta releases without manually specifying URLs. The software also supports one‑click uploading of saved blobs to external services like TSS Saver and SHSH Host.

It is aimed at iOS users who need to preserve signing blobs for future firmware installations, particularly those who prefer a visual workflow or automated scripting via the CLI. The cross‑platform design works on macOS and other operating systems, leveraging Java 21 and Gradle for building, and distributes installers created with tools such as Inno Setup.

The project is released under the GNU GPL v3.0‑only license, with source code and nightly builds available on GitHub, and it includes a wiki for troubleshooting and a feedback channel through GitHub issues.
