White-Label Next.js Development, defined.
White-label Next.js development is when an agency sells a Next.js build to its client and a partner studio writes the code behind the scenes. Blackbyrds Digital delivers App Router projects — server components, dynamic routes, ISR, headless CMS integration, and the metadata and structured-data layer that makes them rank — in your repo or ours, documented and deployed under your agency name. You keep the client, the strategy, and the credit.
You sell. You manage the client. We build.
Background
What Next.js actually buys your client
Next.js is the React framework most agencies land on once a marketing site outgrows a page builder: server-rendered pages that arrive fast and crawl cleanly, a component model your designers can extend, and an application layer waiting for whenever the "just a website" grows a login, a dashboard, or a checkout. The App Router in Next.js 14 pushes most of the work to the server, which is why a well-built Next.js site tends to beat the WordPress build it replaced on Core Web Vitals without a caching plugin in sight.
The catch is that Next.js rewards teams who know it and punishes teams who do not. Server and client component boundaries, caching and revalidation, streaming, route handlers, and metadata generation are all easy to get subtly wrong, and the failure modes show up as slow pages, stale content, or a hydration error nobody can reproduce. That is the gap agencies hire us to close: you sell the outcome, we own the framework decisions that make it hold up in production.
Why agencies bring us Next.js work.
Your clients are asking for it by name
Next.js has crossed from a developer preference into a client requirement — often because their in-house marketer read about Core Web Vitals or their last agency left them stuck on a slow theme. Saying yes without a React team is how agencies end up subcontracting mid-project, at a worse rate, under deadline.
React talent is expensive to keep idle
A senior Next.js developer is a full-time cost that only pays off if you have a full-time pipeline of Next.js work. Most agencies have it in bursts. Partnering converts that fixed cost into a per-project one you can quote against and mark up.
The hard parts are invisible in a pitch
Caching strategy, revalidation, image optimisation, and the metadata layer never appear on a proposal — but they decide whether the site is fast and indexable six months later. We treat those as the deliverable, not the afterthought.
You need someone who can inherit a codebase
Plenty of agency work is not greenfield: a client arrives with a half-finished Next.js project or an aging Pages Router app that needs to move forward. We take over existing repositories, document what we find, and give you an honest read on what is worth keeping.
What we deliver.
Next.js 14 App Router builds — server components, route handlers, streaming, and dynamic rendering where it earns its keep
Design-to-code from Figma with a component library your team can extend, documented in Storybook
Headless CMS integration so your client edits content without calling you
The technical SEO layer: metadata, canonical URLs, Open Graph, XML sitemap, robots, and JSON-LD structured data
Core Web Vitals work — image optimisation, font strategy, bundle discipline, and caching that survives a content update
Forms, integrations, and API routes: CRM handoffs, email delivery, payment providers, third-party services
Deployment on Vercel or your client’s host, with preview environments for review
Migration from WordPress, Webflow, or an older React app, with redirects mapped so rankings survive the move

How we approach it.
- 01
You bring the project
Send us the brief, the designs, or just the client conversation so far. We work from whatever you have — a Figma file, a scope doc, or a half-formed idea you are still selling.
- 02
We scope and plan
You get a written scope, a technical approach, a timeline, and a fixed quote you can mark up before it reaches your client. If something in the brief will not work, we say so before you commit, not after.
- 03
We build behind the scenes
Development runs in your repo or ours, with progress you can show a client. We can stay invisible in email and calls, or join them under your brand. Your call, agreed up front.
- 04
You deliver it to your client
Handover is documented, deployed, and yours. The work ships under your agency name — we do not contact your client, pitch them, or appear in the credits unless you ask us to.
How the white-label part works.
Your repo or ours
We can work inside your GitHub organisation with our own accounts, or run the project in our repository and transfer it on handover. Either way you get the commit history, the documentation, and the environment setup at the end — not a zip file and a good-luck note.
Reviewable progress, not status updates
Every branch gets a preview deployment. You send the link to your client, or screenshot it into your own project tool — the work is demonstrable at any point without a call.
We stay off the client thread
By default we communicate only with your team. If you would rather have us join a technical call under your agency’s name, that is a decision you make per project, not a default we assume.
When agencies call us in.
The marketing site that has to be fast
A brand or campaign site where Core Web Vitals and organic search are the point. Design comes from your team, the front end and CMS wiring come from ours.
The website that grew an application
A client site that now needs accounts, a portal, a dashboard, or a booking flow. Rather than bolting a second system onto a page builder, we extend the Next.js app your client already has.
The replatform
Moving off a slow WordPress theme or an abandoned React build. We audit first, map the redirects, and migrate content so the client does not lose the traffic they are paying you to protect.
Overflow capacity on a project you already sold
Your developers are booked and the client already signed. We pick up a scoped slice — a set of templates, an integration, a launch — without needing to own the whole project.

Next.js FAQ
Questions agencies ask first.
Can you work inside our existing Next.js codebase?
Yes. We take over existing repositories regularly, including Pages Router projects that need to move to the App Router. The first deliverable on an inherited codebase is a written read on what we found — what is solid, what is risky, and what we would change before adding to it — so you can decide the scope with real information.
Do you write TypeScript?
Yes. We work in TypeScript or JavaScript depending on what your team maintains after handover. If the project is ours to hand over and you have no preference, we default to TypeScript for anything with a data layer.
What do we get at handover?
The repository with its full commit history, the environment configuration, and written setup documentation — enough for your team, or your client’s next developer, to run and extend the project without us. Commercial terms, including anything to do with rights in the code, are agreed per partnership before work starts rather than assumed from a web page.
Will our client know the work was outsourced?
Not unless you tell them. We do not contact your client, appear in credits, or publish work that identifies them without your written approval. Case studies on our site are only published with a partner’s permission.
Can you handle both the design and the build?
We can, but the arrangement that plays to both sides is design staying with you and Figma files coming to us. If you need design too, we have a UX/UI practice and will price it as a separate line so you can take or leave it.
How do you handle deployment and hosting?
Vercel is the default because it is where Next.js features land first, but we deploy to whatever your client’s procurement allows — including AWS, Netlify, or a self-hosted Node environment. Environment variables, preview deployments, and build settings are documented at handover.
