🐟TunaOS ISO Builder

Build a live ISO from any bootable container image — entirely in your browser. Same engine as CI (tacklebox, compiled to WebAssembly). Nothing is uploaded anywhere.

Choose your TunaOS edition

Or build from any bootable container image

Bootable container image

Advanced — customize (flatpaks, packages, repos)

Volume label Flatpak preload list (embedded as /LiveOS/flatpak-preload.json for the live env)

System packages (layered on the installed system via remora — persists across updates)

Custom repositories & setup (advanced)

tbox initramfs URL (optional override — by default the builder appends the tbox live modules to the image's own initramfs automatically) Registry relay URL (CORS shim)

🎉 ISO Build Complete!

Your custom TunaOS ISO is ready. Now you need to write it to a USB drive to make it bootable.

Download and install BalenaEtcher (supports Windows, macOS, and Linux).
Plug in your USB flash drive (minimum 4GB).
Open Etcher, click Flash from file and select your downloaded TunaOS ISO.
Select your USB target and click Flash!.

⚠️ Warning: Writing to the wrong drive can wipe your computer's main storage drive!

Identify your USB drive name (e.g. /dev/sdX on Linux, /dev/diskN on macOS).

Run the following command in your terminal:

sudo dd if=path/to/tunaos.iso of=/dev/sdX bs=4M status=progress oflag=sync

Wait for the write command to complete and safely eject the drive.
