The Wix ADI leverages AI technology to build an ecommerce website in minutes, allowing you to launch your business within an hour or two of signing up. But Squarespace is better than Wix for online sellers looking for stunning designs in niche-specific creative industries. If you’re selling art or prints from your portfolio, Squarespace has the edge.
