Beamo Flasher
A guided desktop app that writes OS images to SD cards and USB drives and verifies every byte.
Free to use, no account required.
Builds are unsigned, so macOS and Windows may warn on first launch (on macOS, right-click the app and choose Open). View all v0.5.34 downloads on GitHub.
What Beamo Flasher does
Write a disk image to an SD card or USB drive, then verify the result.
Guided flashing wizard
Pick an image, confirm the drive, and follow the steps so you do not write to the wrong disk.
Byte-for-byte verification
Every write is checked after it finishes.
Batch provisioning
Flash several SD cards or USB drives in one run.
Card-health tracking
Beamo Flasher can set aside cards that keep failing.
Adapts to your hardware
Write speed can rise or ease off to match your machine and drives.
Bring your own image
Flash common raw images, including .iso, .img, .raw, .dd, and .wic, or stream .xz, .gz, .bz2, .zip, .tar, .tgz, and .tbz2 archives. For the Raspberry Pi OS preset, use the separate Beamo Pi app.
