What does website data portability mean, and how to check if your builder lets you leave

Website data portability is your ability to export your website and move it somewhere else without losing it. High portability means you can leave and take everything with you; low portability means you are locked in. A portability scorecard rated website builders around 5 out of 10 and self-hosted WordPress 10 out of 10 (D3, 2026).

Quick answer

• Website data portability measures whether you can export your full website and move it to another platform.
• DreamHost (2025) describes a website as four parts: content, design, data, and infrastructure.
• A portability scorecard rated website builders around 5 out of 10 versus self-hosted WordPress at 10 out of 10 (D3, 2026).
• Wix states in its own Terms of Use that you cannot export a Wix website to another platform (WP Astra, 2025).
• With self-hosted WordPress you own 100 percent of your files, content, and database (WPBeginner, 2026).

What does website data portability mean

Portability is the freedom to take your website and leave. It covers four things DreamHost (2025) calls the components of a website: content (your text and images), design (the code and templates), data (your database and records), and infrastructure (the hosting). A platform with high portability lets you export all four and rebuild elsewhere; a platform with low portability keeps some of them locked inside. The simplest definition is this: can you walk away with the whole website, or only part of it.

Why does website portability matter for a small business

Because portability decides what you lose if anything changes. If a platform raises prices, changes its terms, or shuts down, the pieces you cannot export are gone, and you may have to rebuild from scratch. We cover that exact risk in what happens to your website if your website builder shuts down or raises prices. Portability is also tied to ownership, because you can only truly own the parts you can take with you, a point we expand on in do you own your website if you built it with a website builder.

The five-point checklist to test your builder

You can score any platform in a few minutes with five questions. First, can you export your content as files you keep. Second, can you export or freely recreate your design. Third, can you access your database or records directly. Fourth, can you move to a different host. Fifth, do you control your own domain. A platform that passes all five is fully portable; the D3 (2026) scorecard rates most website builders around 5 out of 10 on these measures, while self-hosted WordPress scores 10 out of 10.

Can you export your website from Wix or Squarespace

Only partly, and the gaps are the whole design. Wix lets you pull blog posts out through an RSS feed but not your full pages or images, and the migration is partly manual (Duplicator, 2025). Squarespace supports a partial export of basic content but not your design or full structure (SaffireTech, 2026). In checklist terms, both pass on content but fail on design and host switching, which is why they land around the middle of the portability scale rather than the top.

What full website portability looks like

Full portability means every one of the five checks passes, which is the normal state for self-hosted WordPress. You own 100 percent of your files, content, and database (WPBeginner, 2026), you can export the whole website, and you can move it to any host. Because WordPress is open source and free, and W3Techs detected it on about 43 percent of all websites in 2026, finding a new host or help is easy. That combination is what earns it a 10 out of 10 on the D3 (2026) scorecard.

Does your domain name move with you

Yes, and this is the one piece most people overlook. ICANN grants you the exclusive right to use a domain name rather than freehold ownership of it (DreamHost, 2025), but that right is portable. You can transfer a domain between registrars and point it at a new host, so your web address stays the same even when you change platforms. Keeping the same domain protects your existing traffic and your search ranking, which matters because 46 percent of all Google searches have local intent (Backlinko, 2024) and your address is part of how people find you.

How to check portability before you commit

Do the test before you build, not after. Ask any platform the five checklist questions and get the answers in writing, the same way you would read a lease before signing it. If a platform cannot export your full website, treat that as renting, and plan for the day you might want to leave. If you are choosing now, a website built on self-hosted WordPress passes the checklist by default, which is why it is the safe long-term home for a small business website.

Frequently asked questions

What does website data portability mean

Website data portability is your ability to export your website, your content, your design, and your data, and move it to another platform or host. High portability means you can leave and take everything with you. Low portability means you are locked in. A portability scorecard rated website builders around 5 out of 10 and self-hosted WordPress 10 out of 10 (D3, 2026).

Why does website portability matter

Because the parts you cannot export are the parts you can lose if a platform raises prices, changes terms, or shuts down. DreamHost (2025) describes a website as four components: content, design, data, and infrastructure. Portability is the test of how many of those four you could walk away with, and it decides whether leaving a platform is easy or a full rebuild.

How do you check if your website builder lets you leave

Run a five-point check: can you export your content, can you export or recreate your design, can you access your database, can you switch hosts, and do you control your domain. Wix states you cannot export a Wix website (WP Astra, 2025), Squarespace allows only a partial export (SaffireTech, 2026), and self-hosted WordPress passes all five.

Can you export your website from Wix or Squarespace

Only partly. Wix lets you pull blog posts through an RSS feed but not your full pages or images, and the move is partly manual (Duplicator, 2025). Squarespace offers a partial export of basic content but not your design (SaffireTech, 2026). Neither gives you the full website, which is why both score lower on portability than WordPress.

What does full website portability look like

With self-hosted WordPress you own 100 percent of your files, content, and database (WPBeginner, 2026), so you can export the whole website and move it to any host. WordPress is open source and free, and W3Techs detected it on about 43 percent of all websites in 2026, which makes finding a new host and help easy.

Does your domain name move with you

Yes. ICANN grants you the exclusive right to use a domain name rather than outright ownership (DreamHost, 2025), but that right is portable, so you can transfer a domain between registrars and point it at a new host. Your web address stays the same even when you change platforms, which protects your traffic and search ranking.

The bottom line

Portability is the quiet feature that decides whether your website is an asset you own or a rental you can lose. Run the five-point checklist on any platform before you build, and favor the option that lets you export everything and move hosts freely.
