What Popsicle is

Popsicle is a free Linux utility for flashing multiple USB devices in parallel. It provides both a command-line interface and a GTK front end, and its device list updates as devices are added or removed. The listed supported devices include SD cards. The project includes AppImage packaging and Flatpak support, as well as a Flatpak manifest; in Flatpak, device discovery uses the UDisks2 D-Bus API. The project says the switch to that API removed the need to launch Popsicle as root. Windows ISO files are not supported, and the app warns if one is selected. Popsicle does not support multiboot, and image downloads are local-only. It is MIT licensed. Building the GTK front end requires GTK and D-Bus development dependencies, while both front ends require Rust's cargo utility. Translators can contribute through pull requests. The software is hosted under the pop-os GitHub organization.

Who it suits

Popsicle suits Linux users who need to flash several USB devices at once and want either a CLI or GTK interface. Building it may suit users with the required development dependencies and Rust's cargo utility.
