Best WordPress to Next.js Migration Services in 2026, Compared Honestly

If you're shopping for a WordPress-to-Next.js migration, you'll notice something odd: almost every "best migration services" list is written by one of the vendors on it, and almost none of them say so.

This one is too — Greeto Studio is on this list, and we wrote it. So here's the deal: our entry is clearly marked, every fact about the other providers comes from their own public websites (checked July 2026, linked so you can verify), and the criteria are the ones we'd use if we were buying instead of selling. If a competitor fits you better, this page should help you figure that out quickly.

How we compared them

Migration vendors are hard to compare because most don't publish prices and all of them claim "zero downtime" and "no SEO loss." So we compared what can actually be verified:

• Published pricing — do they put numbers on their site, or is it "contact us"?
• Stated timeline — what they publicly commit to, not what sales says.
• Proof before contract — can you see real output (a demo, an audit) before paying?
• SEO-safety mechanics — do they describe how rankings survive (a redirect map, route parity, metadata QA), or just promise that they will?
• Best for — team size and situation where each provider genuinely fits.

The comparison at a glance

Now the detail — what each provider actually publishes, and what stands out.

Nandann Creative — the price-transparent option

Nandann is the only provider here with full package pricing on the page: Standard $1,700–4,000, Premium $4,000–8,500, Enterprise $8,500+, with 30 days of post-launch support on the standard tier. They claim 100+ WordPress migrations and quote 40–60% faster load times, with timelines from 1–2 weeks for simple sites up to 2–4 months for complex ones.

What stands out: publishing real prices in a market that hides them. That alone makes Nandann the easiest first quote to get and a useful anchor for comparing everyone else's proposals.

Worth asking: how the fixed tiers handle scope surprises — plugin-heavy WordPress sites rarely map cleanly onto a package price.

Matt Darm — the UK small-business route

Matt Darm runs a UK studio with three published tiers: a £299 consultation, £2,499 standard migration, and £4,999+ for a full migration plus CMS (ex VAT). The process is a familiar three-step: discovery, content/functionality migration, then testing, SEO and launch, with a month of support after.

What stands out: the £299 paid consultation is a low-risk way to get a professional read on your site before committing — cheaper than a bad migration.

Worth asking: marketing claims like "100% SEO kept" and "3.5× avg. ROI improvement" are aggregate marketing numbers; ask what they're measured against for a site like yours.

Pagepro — the strongest pre-contract proof

Pagepro migrates to one opinionated destination — Next.js on Vercel with Sanity as the CMS — at a fixed price agreed after a free readiness assessment, from $15,000 (complex data migrations from $30,000), on a published 4-week schedule.

What stands out: the 48-hour demo. Before any contract, they rebuild a slice of your actual site on their stack with your real content. That's the best pre-sale proof mechanism on this list — you see your own site running on the new stack before you spend anything.

Worth asking: whether Sanity fits your editors. The single-stack focus is why they're fast; it's also a constraint if you wanted a different CMS.

ByteLogic — the running-cost argument

ByteLogic (England & Wales) leads with hosting economics: they publish a comparison of WordPress baseline costs (£83–314/mo) against ~£20/mo on Vercel Pro after migration, and quote projects per-site after a free audit. Published process: audit (1–2 days) → build & preview (1–2 weeks) → review → one-day switch → 2–4 weeks of monitoring, typically 3–5 weeks end to end, with the old WordPress site kept as a rollback.

What stands out: honest safety design — they explicitly keep WordPress running as a backup and describe DNS reversion, which matches how we think about DNS cutover risk.

Worth asking: the £20/mo figure is infrastructure only; get the project fee in writing at the audit stage.

webvise — AI-assisted, discovery-priced

webvise (Potsdam, Germany) pitches migration as an escape from plugin maintenance and quotes 2–3 weeks for simple brochure sites, 4–6 for complex ones, targeting 90+ PageSpeed. Pricing is estimated after discovery. They mention AI-assisted content editing support, without much public detail on how it works.

What stands out: refreshing honesty in the FAQ — they acknowledge rankings can move during a migration and focus on reducing that risk rather than promising it away.

Worth asking: for specifics on what the AI assistance actually does, and for examples of migrated sites with before/after numbers.

Blazity — the enterprise engineering house

Blazity plays a different game: enterprise Next.js migrations (from Angular, Vue, and legacy React as well as CMS-driven stacks), no published pricing or timeline, and an open-source AI migration agent plus the widely used next-enterprise boilerplate on GitHub.

What stands out: the open-source footprint is real proof of engineering depth — you can read their code before you ever talk to sales.

Worth asking: if you're a marketing site under ~200 pages, you're probably not their target customer, and the quote will likely reflect that.

Greeto Studio — our entry (read with that in mind)

This is us, so judge accordingly: our Next.js migration service runs migrations as controlled engineering projects — full route parity, a tested redirect map, metadata and schema QA, and post-launch monitoring — built by a supervised AI system with a human engineer accountable for every change.

Two things we'll point at instead of adjectives. First, the process is public: our migration playbook and SEO migration guide describe exactly what we do, step by step — you can hand them to any vendor on this list and ask "do you do all of this?" Second, we migrate our own properties the same way and publish the data: our own domain migration log shows real Search Console numbers from week one, including the parts that dipped.

We don't publish package pricing yet — migrations are quoted per site after we've seen the actual WordPress install. If you want a number, tell us about your site and you'll get a scoped quote, not a sales call.

Best for: B2B and SaaS marketing sites that want AI-speed delivery without giving up a named engineer who is accountable for the result.

How to choose (whoever you pick)

A migration is a controlled replatform, not a redesign — the vendor's mechanics matter more than their portfolio. Whoever you talk to, ask these five questions:

1. Show me the redirect plan. Every old URL needs a mapped 301 before cutover. If they can't describe their redirect-map process, walk away.
2. What's your route-parity check? How do they prove every indexed page exists on the new site — sitemap diff, crawl comparison, or hope?
3. What happens to my metadata and schema? Titles, canonicals, and structured data silently drifting is the most common way migrations bleed rankings.
4. What do I see before I sign? Pagepro's demo, ByteLogic's audit, Darm's consultation — every serious provider has some pre-contract proof. "Trust us" isn't one.
5. Who's watching after launch? The first two weeks after cutover are where problems surface. Monitoring should be in the quote, not an upsell.

If you'd rather sanity-check the whole thing yourself first, our WordPress-to-Next.js migration guide covers the full sequence — it's the same checklist we run internally.

FAQ

How much does a WordPress to Next.js migration cost in 2026?

Published prices across providers on this page range from about $1,700 for a simple site (Nandann's standard tier) to $30,000+ for complex content architectures (Pagepro), with UK options like Matt Darm from £2,499. Most providers quote per project after an audit, so treat published tiers as anchors — the real driver is how many templates, plugins, and custom features your WordPress site has.

How long does a WordPress to Next.js migration take?

For a typical marketing site, the published timelines cluster around 3–6 weeks including post-launch monitoring: Pagepro commits to 4 weeks, ByteLogic to 3–5, webvise to 2–6 depending on complexity. Simple brochure sites can be done in 1–2 weeks; plugin-heavy or e-commerce sites can run 2–4 months.

Will migrating from WordPress to Next.js hurt my SEO?

Not if route parity, 301 redirects, and metadata are handled properly — rankings typically wobble for a week or two and then recover or improve as Core Web Vitals get better. The risk is real when a vendor skips the redirect map or launches with missing pages, which is why the questions above focus on mechanics rather than promises.

Can AI do the migration instead of an agency?

AI dramatically speeds up the mechanical parts — content extraction, template conversion, redirect generation — and both Blazity (open-source migration agent) and Greeto (supervised AI build system) use it openly. What AI doesn't replace is accountability: someone must verify route parity, test the redirects, and own the launch. The practical question isn't "AI or agency," it's whether the human supervising the AI shows you their checks.
