Ventoy is an open source tool to create bootable USB drive for ISO files. With ventoy, you don't need to format the disk again and again, you just need to copy the iso file to the USB drive and boot it.

Comments about Ventoy as an Alternative to Rufus
It allows simple drag & drop of ISO files to a USB drive and then offers a Grub-style menu to select which ISO to boot from, as opposed to having to outright "burn" the ISO to a drive.
Not 100% compatible, but 99.999%.
Create a separate partition for booting and a special one for placing OS ".iso" files easily.

I have over 20 ISOs on one flash drive because of this utility. It's my favorite software for multiboot USBs. Keep in mind, however, that it doesn't work on any Mac hardware.
