Every major website platform is being rebuilt around code and AI agents. Four questions decide whether that’s your problem or someone else’s.

“Vendor lock-in” gets used as an accusation, usually by someone selling the alternative. It’s more useful as a number.
Everyone has some. A WordPress owner who can’t read their own database is locked in. A Shopify merchant who can’t take their checkout is locked in. Someone with a bespoke site and one freelancer who knows how it works is extremely locked in, and usually doesn’t realise because nobody sold them a subscription.
The question isn’t whether you’re locked in. It’s whether you know your number, and whether it’s proportionate to what the site is worth.
Here’s how to find out. Ten checks, three minutes each, no technical knowledge required. Score each 0, 1 or 2 and total out of twenty.
Test: try to export your blog posts, case studies or products right now, with their fields intact, in a format someone else could import.
2 — you get structured data (CSV, JSON, an API) with every field.
1 — you get some of it, or a static snapshot without the structure.
0 — you can’t, or you’d be copying and pasting.
Cheap fix: schedule a monthly export to storage you control. Most platforms have an API or a CSV export. This costs an hour to set up once.
Worth knowing: Webflow’s own engineering post concedes that while you can export your code, you couldn’t edit that export and bring it back. The export exists; the round trip doesn’t. Most platforms are the same and fewer are honest about it.
Test: if you moved, would any of the layout come with you in a usable form?
2 — you have components, a design system, or code you could hand to someone.
1 — you’d have visual reference but would rebuild.
0 — you’d start from a screenshot.
Realistically most people score 1 here and it’s fine. Rebuilding a front end is the cheapest part of moving now.
Test: log in to your domain registrar. Right now.
2 — you know where it is, it’s in the business’s name, you could repoint it today.
1 — you have access but someone else set it up.
0 — you don’t know who holds it, or it’s in an agency’s account.
Cheap fix: this is the single highest-value hour you’ll spend. Get the registrar and DNS into an account the business owns, with billing on a company card. Nothing else on this list matters if someone else controls where your domain points.
Test: do you have a current list of every URL on your site?
2 — yes, maintained.
1 — you could generate one from a sitemap.
0 — no idea how many pages you have.
This is the item that turns a routine migration into a disaster. Every URL that changes without a redirect is a page that disappears from search and every link pointing at it that breaks. It’s also the cheapest thing on the list to sort out.
Test: can you retrieve every enquiry you’ve received in the last two years?
2 — they go to your CRM or inbox and you hold the history.
1 — they’re in the platform and exportable.
0 — they’re in the platform and you’ve never checked.
Cheap fix: route form submissions to somewhere you own as well as wherever they currently go.
Test: if you have gated content, who holds the user identities?
2 — a dedicated provider, or your own database.
1 — a third-party tool bolted to the site.
0 — a feature bundled into your website platform.
If you scored 0, note that this is exactly the position Webflow’s User Accounts customers were in before it was switched off on 29 January 2026. Not a hypothetical.
Test: what happens to your workflows if the tool running them stops?
2 — they’re in a dedicated automation platform you pay for separately.
1 — a mix.
0 — they’re built into your website platform.
Webflow’s Logic was disabled on 27 June 2025. Flows stopped. Forms connected to them reverted to ordinary forms.
Test: could you get three years of traffic data out?
2 — you run something independent and own the data.
1 — you have a platform-native tool and an independent one.
0 — platform-native only.
Native analytics almost never export. You lose your baseline exactly when you most need it — right after a migration, when you’re trying to work out whether it went well.
Test: how many people could publish a change to your site this afternoon?
2 — two or more, at least one on your payroll.
1 — one person, on your payroll.
0 — one person, not on your payroll.
Be honest here. This is the most common form of real lock-in I see, it has nothing to do with which platform you chose, and people who worry loudly about vendors often score zero on it.
Test: what would it cost to stop paying next month?
2 — monthly, no notice, no seat commitment.
1 — annual billing you’d ride out.
0 — a contract with notice, or a seat count you’re locked into.
16–20 — Portable. You could move if you needed to. You probably don’t need to. File this and get on with your week.
10–15 — Harden it. You have two or three specific dependencies worth removing. Not a migration — a Tuesday afternoon. Do those and re-score.
Under 10 — You have a tenancy, not a website. Worth taking seriously, though see the last section before you spend anything.
If you do nothing else:
Four hours, roughly, and a typical score moves five or six points. No migration, no new platform, no invoice.
If you do decide to move, the cost sits in places people don’t expect. Design is cheap now. Content mapping and redirects are not, and they’re where migrations go wrong.
Rough bands, and treat these as orientation rather than quotes:
Most SME sites sit well below any of those numbers. Get a quote before you assume.
I’d rather say this plainly than have you spend money on my account.
If your website generates no revenue, costs £30 a month, and would take a fortnight to rebuild, then portability is a rounding error. A score of six is completely rational. Don’t spend £5,000 insuring against a £2,000 risk — that’s just a worse version of the problem.
The score matters in proportion to what the site does. A site that carries your entire enquiry pipeline, holds customer data, or has ten years of accumulated search authority deserves a serious answer. A five-page brochure doesn’t.
Work out which one you’ve got first.

→ Next: Builder, Headless, or Bespoke
TL;DR
Lock-in isn’t binary and it isn’t about a vendor’s ethics — it’s the sum of ten specific dependencies. Most can be reduced this afternoon without moving anything. Score yours out of twenty, and if it’s low but your site earns nothing, that’s fine.
