Why pick OpenCart?

OpenCart is a lean, genuinely free cart that is easy to spin up and supports multiple stores from one admin. Its core stays minimal, so you will lean on the paid extension marketplace and your own hosting know-how.

Best for: Developers wanting a simple, free self-hosted cart

Why pick Square Online?

Square Online is the obvious add-on for businesses already running Square POS in the real world. The free plan is genuinely usable, though serious online-first brands will outgrow its lighter feature set.

Best for: Retail & restaurants already using Square
