Why balenaEtcher?

Here at balena we have thousands of users working through our getting started process, we found there was no easy way for our users to flash an SD card that we could recommend to everyone.

So we built Etcher, an SD card flasher app that is simple for end users, extensible for developers, and works on any platform.

Create USB installation media from bootable ISOs
Install almost any OS to almost any flash drive
Offer an easy way for your users to flash your OS using our ‘Flash with Etcher’ feature
