We build on all of them, so we've no reason to push one over another. The right choice comes from the job.
Reach for WordPress when…
You publish a lot of content and want a familiar editor. It's flexible and everywhere.
Reach for Shopify when…
You're selling products and want payments, inventory, and shipping handled for you out of the box.
Go custom when…
Your idea doesn't fit a template — a product, a platform, or logic no plugin covers. Custom costs more up front and pays back in fit.
