I’d like to start a discussion to identify the best platforms for mobile-friendly online selling. With mobile shopping now the default for many consumers, I’m interested in tools that deliver strong mobile UX, fast load times, and optimized checkout flows—without needing heavy custom development.
Here are a few platforms ranked highly in the G2's E-commerce Platforms category that support mobile-first selling:
Shopify offers mobile-optimized themes and a responsive checkout by default. The Shopify Mobile app also allows store owners to manage inventory, track sales, and respond to customers on the go. Merchants can enable Shop Pay for an even faster mobile checkout experience. Performance on mobile is consistent across most themes.
BigCommerce supports mobile-first design with responsive templates and full control over mobile layout via headless or stencil frameworks. Storefronts load quickly and are optimized for SEO and product discovery across mobile search engines. It’s also compatible with mobile wallets like Apple Pay and Google Pay.
Wix includes a dedicated mobile editor to adjust how sites appear on smaller screens. Its native e-commerce tools work well for small businesses looking for mobile storefronts that are quick to deploy. Wix also supports mobile checkout, product zoom, and customer chat tools directly in the mobile view.
Squarespace automatically creates mobile-friendly versions of each template and supports dynamic resizing for images and product grids. It’s best known for clean, minimalist design—great for visual product brands. Its mobile checkout is sleek, though more limited in customization compared to Shopify or WooCommerce.
WooCommerce relies on your WordPress theme for mobile responsiveness, so results vary depending on the setup. That said, many themes from WooCommerce.com and third-party providers offer strong mobile performance. Store owners have the flexibility to tweak checkout flow, optimize images, and even build headless frontends tailored for mobile.
If you’ve tested any of these platforms with a mobile-heavy audience, I’d like to hear which delivered the best experience in terms of speed, checkout conversion, and ease of setup.
