Hi @ParkHaein, how are you?
I’m only a user of Builder.io too. @korey once explained perfectly. You will measure you bandwith by your traffic and contents on your page. If you have a lot of images or some heavy files on your page, every load from client need to dowload all files, so that will increase your bandwidth, a lot. So optimize heavy images, if you are using videos, do not load him when load your website. I already had some clients that they didnt worried about heavy files and they consumed a lot of bandwidth.
I undestood from plans that bandwidth reset every month. But someone can tell more about. I started to use this month only, so i am a newbie here.
Have a great day!
