Which one is better, the open source program?

admin

Please recommend some open-source e-commerce platforms that I can modify myself and use for my own purposes. I don't know much about technology, so I'm not sure which architecture is better or easier to set up, which one has the fastest speed, and how much cheaper it would be to redevelop with the help of others. Or if there are any other better open-source mini-marketplaces you could recommend.
