Etcher

balenaEtcher is a cross‑platform utility that writes operating‑system images to SD cards and USB drives. It presents a three‑step graphical workflow—select image, choose target, and flash—without requiring command‑line interaction. The software validates the write operation and hides internal system drives by default, reducing the risk of accidental data loss.

Designed for makers and developers, Etcher supports bootable ISOs and a wide range of OS images, making it suitable for creating installation media or preparing devices for IoT deployments. Its interface is built with JavaScript, HTML, Node.js, and Electron, and the project is released under an open‑source license, ensuring it remains free to use and modify.

Etcher runs on macOS, Windows, and Linux, offering a consistent experience across desktop environments. Community resources such as forums and documentation are provided, and the tool can be integrated into websites via a “Flash with Etcher” button to simplify end‑user image flashing.
