What Is a TYPO3 to Next.js Migration?

Here's what actually happens during a TYPO3 to Next.js migration: we install the EXT:headless extension on your TYPO3 backend, which turns your content, navigation, and forms into JSON API endpoints. A Next.js app sits in front of all that, consuming those APIs to serve server-rendered or statically generated pages. Your editors don't touch a new CMS. Visitors get a frontend that's genuinely fast.

Your Current Site May Be a Liability

Common gaps we find in nearly every audit.

Monolithic TYPO3 renders every page server-side on every single request

Risk: That means slow TTFB, poor Core Web Vitals, and search rankings that quietly slip.

The frontend's locked to Fluid templates and jQuery-era patterns

Risk: Good developers won't touch it, and hiring gets harder every year.

Multilanguage and multidomain setups turn into TypoScript spaghetti over time

Risk: One content update can silently break other locales—and you won't find out until someone complains.

Extensions like EXT:form and EXT:news don't just work headless out of the box—they need custom JSON mapping

Risk: Skip that step and you end up with a half-migrated site where forms don't submit and news feeds return nothing.

When backend and frontend share the same deployment, a TYPO3 core update can take down your entire public-facing site

Risk: That's a bad day.

Without static generation or edge caching, your server costs climb in lockstep with traffic instead of staying flat.

Risk: Server costs scale linearly with traffic instead of staying flat

What Your Website Could Look Like

Custom-designed for your industry. No templates. No stock photos.

How We Build This Right

Every safeguard, built in from Day 1.

EXT:headless Configuration

We install and configure the FriendsOfTYPO3 headless extension with site YAML flags, redirect middleware, and custom JSON output. Every content element ends up with a clean, typed API contract before we write a single line of frontend code.

Content Element Mapping

Every content element—standard and custom—gets mapped to a TypeScript interface and a matching React component. Nothing gets left out.

Multilanguage & Multidomain

We replicate your TYPO3 language fallback chains and domain routing in Next.js using i18n routing and middleware. All your locale URLs stay intact, so there's no SEO disruption at cutover.

Form & Extension Support

EXT:form, EXT:news, EXT:powermail, EXT:felogin, and EXT:solr each get dedicated Next.js integrations—proper POST handling, finisher support, the works.

SEO & Redirect Preservation

Every URL, meta tag, and 301 redirect gets exported from TYPO3 and rebuilt in Next.js. Structured data and canonical tags come with it.

Performance Benchmarking

We run Lighthouse audits before and after migration on every template. The target is 90+ across Performance, Accessibility, Best Practices, and SEO.

What We Build

Purpose-built features for your industry.

JSON API Audit

Before writing any frontend code, we map every content type, plugin, and custom CE to confirm full headless API coverage. No surprises two weeks into the build.

Next.js Component Library

Each TYPO3 content element gets a purpose-built React component with TypeScript types generated directly from the JSON schema.

ISR & Static Generation

High-traffic pages generate statically at build time. Editorial content revalidates on demand through Incremental Static Regeneration—so editors don't have to wait for a full rebuild to see their changes live.

Editorial Preview

Next.js draft mode connects to TYPO3 workspaces so your editors can preview unpublished content exactly the way visitors will see it. No more "it looked fine in the backend."

Decoupled Deployment

TYPO3 stays on your existing infrastructure. Next.js deploys to Vercel or your preferred edge platform with its own CI/CD pipeline, completely independent.

Workspace & Auth Support

EXT:felogin and TYPO3 workspace previews work through the headless layer using JWT-based session handling.

Our Development Process

From discovery to launch. Quality at every step.

TYPO3 Audit & API Mapping

Week 1-2

We start by inventorying every page type, content element, extension, language, and domain in your TYPO3 instance. You get a complete JSON API contract and a migration scope document before anything gets built.

EXT:headless Setup & Customization

Week 2-3

Next, we install and configure the headless extension, write TypoScript overrides for custom CEs, set up site YAML flags, and verify JSON output for every content type.

Next.js Frontend Build

Week 3-6

Then we build the component library, routing, i18n setup, forms, and authentication layer in Next.js—each component tested against the live TYPO3 API as we go.

SEO Migration & QA

Week 6-7

Before launch, we import all redirects, validate every URL, run Lighthouse audits, do cross-browser testing, and run a side-by-side content comparison against the original site.

Cutover & Post-Launch Support

Week 8

Cutover is a DNS switch with zero-downtime deployment. After that, you get 30 days of monitoring, bug fixes, and editor training on the new preview workflow.

Frequently Asked Questions

Yes—and that's really the whole point. Your editors keep working in TYPO3 exactly as they do now: creating pages, managing content, handling translations. The EXT:headless extension exposes all of that as JSON APIs. Next.js consumes those APIs and handles everything on the frontend. Two systems, cleanly separated, neither dependent on the other.

EXT:headless supports EXT:news, EXT:form, EXT:powermail, EXT:felogin, EXT:gridelements, and TYPO3 Solr out of the box. Custom extensions need TypoScript overrides to expose their data as JSON—we audit every installed extension during discovery and build those custom mappings where needed.

A typical mid-size migration—200 to 500 pages, multiple languages, standard extensions—takes 6 to 8 weeks. Larger sites with custom content elements, complex form workflows, or Solr integrations can run 10 to 12 weeks. We give you a fixed timeline during scoping, not a vague range.

We preserve every URL, redirect, canonical tag, hreflang attribute, and structured data block from your current site. Next.js static generation usually improves Core Web Vitals noticeably, which tends to help rankings. We run audits before and after to catch any discrepancies before cutover.

EXT:headless requires TYPO3 v9.5 or higher—though we'd strongly recommend v11 or v12 for the best API support and long-term security coverage. Running something older? We can fold a TYPO3 core upgrade into the migration project with an adjusted scope.

We typically deploy to Vercel for edge caching, instant rollbacks, and built-in preview deployments. Your TYPO3 backend stays where it is; the two systems communicate over HTTPS APIs. If your compliance requirements call for AWS, Netlify, or self-hosted Node.js infrastructure, we can work with that too.
