There is no universal winner here, and a feature-count contest will not find one. A service-business website rarely fails in a comparison table. It fails when an employee cannot update a service, a form quietly stops notifying the right person, a subscription renews on a former contractor’s card, or a move to a new provider turns into a manual rebuild. Every one of those is a question about control, and the platform you pick sets the terms for all of them.

So the more useful way to read “WordPress vs Wix vs Squarespace” is not which builder has the most features. It is which parts of this site will my business actually control, and which am I renting from the platform. That is not one question. It is five — and buyers routinely collapse them into a single word, portability, that hides most of the decision.

“Portability” is five separate things

When a proposal says a platform is “portable” or that “you’ll own your site,” it is usually blending five properties that can each be true or false on their own:

  1. Content ownership — do the words, images, and data belong to you? On all three major platforms, the content you create is yours.
  2. Account control — is the primary account in the business’s name, on a business-controlled email and payment method, instead of a contractor’s personal login?
  3. Implementation portability — can the assembled site — its design, layout, and working features — be moved to run somewhere else, or only its raw content?
  4. Infrastructure — who runs the servers, software updates, and security: the platform, or a host you choose and maintain?
  5. Stewardship — who monitors the site, makes changes, tests the lead path, and investigates when something breaks?

Owning your content tells you nothing about whether you can move the built site, and neither tells you who fixes it at nine at night. Most “who owns the website” disputes are really a mismatch on one of these five, found late. The three platforms differ most on numbers 3 and 4. Numbers 1, 2, and 5 are decided mostly by how the project is set up — not by the logo on the editor.

Read the rest of this article as a way to figure out which of those five properties your business most needs to hold, and then pick the platform that makes holding it easy.

First, make sure you are comparing the right WordPress

“WordPress” names two very different arrangements.

Self-hosted WordPress is the open-source software from WordPress.org, installed on a hosting account you choose. WordPress.com is a hosted service with its own plans, limits, and support model. This article compares Wix and Squarespace mainly with self-hosted WordPress, because that is the version in play whenever a proposal talks about choosing a host, installing plugins, or moving the site between hosting companies. When someone says “WordPress is more portable,” ask which one they mean — and who would control the hosting account, the site files, the database, the theme or builder licenses, and the backups. Portability with none of those in the business’s hands is portability on paper.

The practical comparison

A platform choice bundles the five control properties above into one purchase. Here is how the three land against them for a typical service site.

Decision Self-hosted WordPress Wix Squarespace
Infrastructure You choose and manage the host Included in Wix’s managed service Included in Squarespace’s managed service
Software upkeep Core, themes, plugins, and compatibility need a named owner Wix operates the platform and applies updates Squarespace operates the platform
Extensions Broad plugin and custom-development ecosystem Apps and integrations inside Wix Extensions and integrations inside Squarespace
Account transfer Depends on how hosting, licenses, and admin access were set up Documented transfer to another Wix account Documented transfer to another owner’s account
What leaves with you Content export, plus the files and database when you control them; some pieces depend on licensed themes/plugins Your content is yours, but the built Wix site does not run off Wix Certain content exports to WordPress-format XML; design and several page types do not
Best fit A business with defined technical stewardship, or requirements that reward the flexibility A business that wants one managed environment and accepts the platform boundary A business that wants managed simplicity and likes its editing and design model

The table is deliberately conditional. Each platform can produce a clear, effective service-business website, and each can be implemented badly. What separates them is not quality — it is which control property you give up in exchange for which convenience.

Wix: fewest infrastructure decisions, a firm boundary at the edge

Wix is a software-as-a-service platform: hosting, editor, platform services, and many business tools live in one environment. Wix handles platform setup and updates, and it documents roles and a process for transferring a site to another Wix account. For an owner who does not want to choose a host or maintain a content-management system, that is a real reduction in moving parts.

The boundary shows up on exit. A Wix site relies on Wix’s own services and runs on Wix’s infrastructure; you can point a domain you control at it and you can transfer the site to another Wix account, but you cannot take the assembled Wix site and run it normally on an unrelated host. That is not the same as “you own nothing” — the content you made is yours. It means, in the language above, that Wix gives you strong content ownership and can give you clean account control, while implementation portability is close to zero. If leaving Wix would mean rebuilding the site elsewhere anyway, choose it knowing that, and make sure the business — not a contractor — holds the owner account.

Squarespace: managed simplicity with a partial, specific export

Squarespace follows a similar managed model — no separate host to pick, no plugin-update routine to run — and it documents a direct transfer of site ownership that only the current owner can perform. Settle who that owner is before the project ends, not during an emergency two years later.

Its exit is more generous than Wix’s but narrower than a full copy of the site, and the specifics matter more than “some things don’t export.” Squarespace exports an XML file built for WordPress import. That file carries your layout pages, a single blog page with its posts, and text and image blocks. It does not carry your style settings or custom CSS, your product/store pages, portfolio, index, cover, album, event, or info pages, additional blog pages, dropdown navigation, or audio, product, and video blocks — and Squarespace notes you cannot export from one Squarespace site and import into another. So a Squarespace departure typically preserves useful words and images while requiring a new design and a rebuild of anything that lived in an unsupported page type or block. For a simple service site that is a modest reconstruction; for a store or a portfolio-heavy site it is a larger one. Choose Squarespace when its content and design model fits the site you need and you have checked your required forms and integrations before the build — and treat “leaving” as a content migration plus a rebuild, not a one-click move of the finished design.

Self-hosted WordPress: more freedom, more responsibility to assign

Self-hosted WordPress separates the software from the host. It is open source, and its built-in export produces a file of posts, pages, comments, custom fields, and taxonomies; a full site can be moved by transferring its files and database. That is genuine portability — the built site can, in principle, live somewhere else, which is exactly what Wix cannot offer and Squarespace offers only in part.

Genuine is not the same as effortless. A real WordPress site often depends on a commercial theme or page builder, plugins with their own licenses, custom code, a particular server configuration, external form or scheduling services, and a developer who remembers why each piece was chosen. WordPress’s own documentation tells operators to keep core and plugins updated and to back up before updating. None of that is a reason to reject WordPress; it is the evidence that self-hosted WordPress trades platform-managed infrastructure for flexibility, and the flexibility only pays off when someone actually owns the hosting, updates, backups, restores, and compatibility. Choose it when the requirements reward its ecosystem and a named person or company holds those responsibilities and the business controls the admin and hosting accounts. If nobody owns them, “flexible” becomes “assembled from parts no one wants to touch.”

“Can’t I just switch later?” — yes, at three different prices

Buyers often defer the decision by assuming a later move will be easy. It is possible on all three, at costs that differ by exactly the implementation-portability property above:

  • Leaving Wix means rebuilding the site on another platform. Your content and domain come with you; the build does not.
  • Leaving Squarespace means exporting the content that its XML supports, then rebuilding the design and any unsupported page types elsewhere.
  • Leaving self-hosted WordPress means moving files and a database — the lowest-rebuild path — but only if you also control the hosting account and hold any paid theme, builder, and plugin licenses the site depends on.

“I’ll switch if I outgrow it” is a reasonable plan. Price the switch before you sign, not after.

A related question comes up now that every platform advertises AI: does an “AI website builder” change this? Wix, Squarespace, and WordPress hosts all offer AI tools that draft pages or whole sites quickly. Useful as a starting point — but they are a feature layer inside these same three platforms, not a fourth option. They change how fast a first draft appears. They do not change who controls the accounts, whether the built site can leave, or who tends it afterward, which are the questions this article is actually about.

The control-and-fit scorecard

Score each question 0, 1, or 2 for a platform (or for your current site): 0 = unknown or no; 1 = possible, but needs extra work or a third party; 2 = clearly supported, with a named owner.

Question Score
Can a non-technical employee make the routine changes the business expects?
Does the platform support the required form, scheduling, payment, review, and analytics paths?
Will the business control the primary owner account and billing?
Is responsibility for updates and incidents written down and assigned?
Can an authorized person export the important content and data?
Does the business control the domain and its registrar account?
If the original builder disappears, can another qualified person take over?
Is the expected cost of leaving acceptable to the business?

Do not just total the columns and crown a winner. One zero can outweigh seven twos. If the business must connect to a specialized system, publish frequently through an internal team, or meet a particular data requirement, that single condition can decide the platform on its own — which is the point of scoring the questions instead of counting features.

Before you sign, ask the one exit question that matters most

You do not need the full vendor-departure checklist to choose a platform — that belongs to the day you actually change providers, and there is a dedicated walkthrough for it (see the related reading). For the platform decision, one question does most of the work:

If we ended this next month, what does the business keep, what accounts stay in our name, and what would a new provider have to rebuild?

The domain deserves a specific answer inside that. It is a separate asset from the website, even when one vendor sells both: the business should be the registrant of record, on an account and email it controls, so the site can later point to Wix, Squarespace, WordPress, or a replacement without a rescue mission. Losing the domain is a worse and more urgent problem than changing a page builder. The mechanics of moving a domain and the rest of the handover are covered in the related articles below.

Pick by the property you can’t give up

Pick the platform by the one control property your business cannot afford to give up, and let the others follow. If you most need a non-technical person to run the site with minimal upkeep, a managed platform that fits your requirements earns it. If you most need the built site to be movable and extensible, self-hosted WordPress earns it — provided someone owns the maintenance. If two platforms both clear the bar, prefer the one your team can operate confidently. If one requirement clearly separates them, let that requirement decide.

Before requesting a new build, run the scorecard against the site you already have. The honest result may be a rebuild, a repair, or simply a cleaner ownership and support arrangement on the platform you are already paying for.
