Website platforms and content systems

What a platform actually is

A platform is the software your site is built on top of, and it decides three things before a single page is designed: who can edit what, where the site can be hosted, and how expensive it is to leave. What a CMS actually does covers the general mechanics of that separation between content and presentation. This section is about the specific, named options a small business actually chooses between, and what each one is built to be good at.

Hosted website platforms versus self-hosted software

Every platform on this list sits somewhere on one line: does the platform host itself, or do you host it.

Shopify, Squarespace, Wix and Webflow are hosted. You do not choose a server, apply an update or configure a certificate — the company runs the software, and your monthly or annual fee pays for that. The trade is that you build inside the boundaries the platform sets.

WordPress, in its self-hosted form, is software you install on hosting you choose. Nobody runs it for you by default, which is also why “WordPress” alone does not describe a finished stack the way “Shopify” does — it describes a starting point. A custom build is the same idea taken further: no platform at all, just code, on hosting you choose, doing exactly what was specified and nothing else.

The six website platforms and builders on the market

WordPress — free, open-source, self-hosted by default, extended by plugins and themes. The largest ecosystem, and the largest maintenance obligation.

Shopify — hosted commerce software. Built to take orders; everything else supports that.

Squarespace — hosted, design-led, all-in-one. Narrow scope by design, and that narrowness is most of what you are paying for.

Wix — hosted, drag-and-drop editor, the lowest barrier to a first working page, with built-in ecommerce and scheduling capabilities available as add-on options. What it costs you later is the part rarely mentioned upfront.

Webflow — hosted, but built for people who want CSS-level design control without hand-writing the CSS. A different audience from the previous three.

A custom build — no platform, or a headless one. Maximum flexibility, maximum responsibility, and a cost profile that looks nothing like the other five.

Wix, Squarespace, Webflow, Shopify and WordPress website builders: editors, built-in ecommerce and scheduling options

Each hosted website builder bundles a different set of built-in capabilities into its editor. Wix’s drag-and-drop editor includes built-in ecommerce and scheduling options as add-ons rather than a separate purchase. Squarespace and Webflow both bundle an editor with commerce capabilities, though Webflow’s is closer to a toolkit than a finished checkout. Shopify inverts the order: commerce is the core, and everything else — blog, booking, scheduling — is an extension bolted onto a store rather than the reverse. WordPress ships with none of this built in; every capability, from ecommerce to scheduling, arrives as a plugin — the same flexibility-for-convenience trade covered in website builders and the cost of convenience.

The concepts underneath any of the six

Beneath the named platforms, the same handful of mechanical questions recur regardless of which one is chosen: hosted platform or self-hosted, open source, and what it means when nobody is selling it to you, themes and templates, what you are actually buying, plugins and extensions, and the dependency you inherit, who can edit the site after launch, how a CMS stores your content, static sites explained, and headless architecture in plain terms.

The commercial side of the same decision runs through licence, subscription and transaction costs by platform type, platform lock-in and switching costs, platform versions, updates and end of life, and what happens when a platform is discontinued.

And three narrower, situational questions: multi-site and franchise structures on one platform, site search inside a CMS, and user roles and permissions.

What “flexibility” actually costs

Flexibility is not free on any platform — it is paid for somewhere, and the six options above simply put the bill in different places. A hosted platform charges you in narrower functionality and in fees that increase with usage. A self-hosted platform charges you in the ongoing labour of running the software yourself, or in paying someone else to. The website builder versus CMS distinction is the cleanest way to see this trade-off before choosing.

None of the six is the correct answer in general. There is no single best website platform, only the best fit for a given business’s editor preferences, budget and built-in capability needs. Choosing a platform for your business sets out the questions that actually decide it, and platform lock-in and what switching later costs covers the part most comparisons leave out entirely — that the decision is not really made once.

What this section is not

It is not a ranking. Nothing here concludes that one platform is best, because the honest answer changes with what the business does, who will maintain the site, and what “done” needs to mean for it. Where a specific build decision needs a figure attached — a plan, a subscription, a build quote — that belongs on what drives the cost of a website, not here.
