Your client needs a Node.js REST API, a real-time backend, a NestJS microservices architecture, or an eCommerce API layer and your agency needs it built under your brand by engineers who genuinely know the platform. KiwiCommerce provides white label Node.js developers to UK agencies. Express.js and NestJS. Node.js 22 and 24 LTS. eCommerce backend experience. NDA signed before briefing begins.
White label Node.js development means KiwiCommerce builds your client's Node.js backend the REST API, real-time system, microservice, or eCommerce integration and you deliver it under your agency's brand. Your name on every file and document. Ours nowhere.
Whether you're a digital agency taking on your first eCommerce brief or a marketing consultancy managing multiple client stores, KiwiCommerce works quietly in the background so you can deliver with confidence, every time.
We build for production conditions proper error handling, rate limiting, connection pooling, and monitoring from day one. APIs that work in a demo and APIs that hold under real load are different engineering problems. We solve the second one.
We sign the NDA before hearing the scope. No KiwiCommerce references in API documentation, endpoint naming, code comments, or any deliverable. Your client's backend looks built entirely by your agency.
Every developer is UK-based. Backend development involves live questions about data schemas, integration behaviour, and scope changes. Same-timezone availability means Those questions resolve during your working day.
Node.js is the most widely adopted web framework globally 48.7% of developers use it according to the Stack Overflow 2025 Developer Survey. That adoption means agencies are regularly fielding client briefs involving Node.js backends: REST APIs for mobile applications, real-time features for SaaS platforms, microservices for enterprise systems. When those briefs land and your team does not have the Node.js specialism, white label Node.js development from KiwiCommerce keeps the opportunity in your agency rather than referring it elsewhere.
Free ConsultationNot every Node.js project needs the same framework. Express.js is the right choice for REST APIs where simplicity and flexibility matter. NestJS is correct for enterprise backends and microservices where structure, TypeScript, and long-term maintainability are requirements. Fastify suits high-throughput endpoints where raw performance is the priority. We select the framework based on what the project actually needs not on which one we happen to use for everything. That framework judgement is part of what your agency is engaging when it brings us a Node.js brief.
We sign a non-disclosure agreement before receiving any project details. Client identity, project scope, API design, database architecture, and commercial terms are all protected. No KiwiCommerce reference appears in endpoint naming conventions, API documentation, code comments, README files, or any artefact your client accesses. Your client receives a Node.js backend that reads entirely as your agency's engineering work because in every way they can see, it is.

Every Node.js developer is UK-based. Backend work schema decisions, integration debugging, security configuration needs direct, fast communication. UK timezone means your agency gets answers during the working day, not queued overnight.
We choose Express.js, NestJS, or Fastify based on the project requirements not based on habit. That selection rationale is documented and explained to your team. You know why the framework was chosen and can defend that decision to your client if asked.
For agencies with eCommerce clients needing Node.js backends headless API layers, order management integrations, payment gateway connections we bring eCommerce domain knowledge alongside Node.js engineering. Adobe Commerce Certified and Shopify Experts on the team.

Cannot find what you are looking for? Contact our team.
You brief us on the Node.js framework, backend scope, database stack, and timeline. We build in a staging environment you access throughout. All deliverables, API docs, and code carry your agency name. IP transfers on delivery. No direct client contact unless you direct us onto a call as your team.
Node.js 22 LTS and Node.js 24 LTS both actively maintained and security-patched. Node.js 18 reached end of life in April 2025. If your client’s existing backend is on Node.js 18 or earlier, we assess and plan the version upgrade before taking on ongoing development.
We choose based on the project. Express.js for REST APIs where simplicity and flexibility are the priority. NestJS for enterprise backends, microservices, or projects where TypeScript, structure, and maintainability over a long development cycle matter more than minimal setup. That judgement is part of the senior-level engagement not a default.
Yes. Socket.IO and WebSocket backends for live dashboards, collaborative tools, chat systems, and order tracking. We handle concurrent connection management, event loop behaviour under load, and reconnection logic, not just the happy-path implementation that breaks under real concurrent user volumes.
We sign before you share the brief. NDA covers client identity, project scope, API architecture, database design, and commercial terms. No KiwiCommerce references in API documentation, endpoint naming, code comments, or README files. Your client receives backend code entirely attributable to your agency.
All invoicing is between KiwiCommerce and your agency. Your client never sees our rates. Fixed-price for scoped projects, monthly retainer for ongoing Node.js client accounts. You control your margin throughout. For projects needing a discovery and scoping phase first, we offer that as a defined initial engagement.
Send us the brief framework, scope, timeline. We respond within one business day with an honest assessment.
