Your agency wins a Java brief an enterprise backend, a Spring Boot REST API, a microservices architecture, or a legacy Java modernisation project. Your team does not have the Java specialism. KiwiCommerce delivers it under your brand, on Java 21 and Java 25 LTS, with Spring Boot 4 and Spring Framework 7. Clean, tested, documented Java. NDA signed before briefing. Your agency keeps the client. We handle the code.
White label Java development means KiwiCommerce builds your client's Java application the Spring Boot API, enterprise backend, or microservices architecture 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.
Proper controller-service-repository layering. Spring used correctly. Test coverage on the service layer. Documented API contracts. Java your agency can stand behind when a client's technical team or CTO reviews the codebase after delivery.
Signed before you share the project scope. No KiwiCommerce references in package names, class names, Javadoc, or API documentation. Your client receives Java code entirely attributable to your agency, at every stage and in every file.
Enterprise Java decisions database schema, Spring Security configuration, microservice boundaries need direct, fast communication. Every developer is UK-based. Questions get answered during your working day, not queued for the following morning.
Java 25 LTS (September 2025) and Java 21 LTS are our production targets. Spring Boot 4 and Spring Framework 7 (November 2025) are current. We do not build on end-of-life Java or unsupported Spring versions that carry security risk.
Over 90% of Fortune 500 companies use Java for core backend systems. More than 418,000 companies globally run Java in production. When your agency wins an enterprise client brief on a Java stack Spring Boot API, legacy Java modernisation, enterprise microservices white label Java development means you deliver it without recruiting a Java capability your agency may only need periodically. You present a complete enterprise software offering to clients. KiwiCommerce provides the engineering behind it, invisibly and under your brand.
Java 25 LTS was released in September 2025 and is the current recommended production version for new builds. Spring Boot 4 supports Java 25. Spring Framework 7 was released in November 2025. Spring Framework 6.2.x open source support ends in June 2026 teams still on it need a migration plan. Our developers work on current Java LTS releases and current Spring versions. New builds do not inherit technical debt from outdated framework patterns used in previous-generation Spring applications.
Not all Java briefs are standard REST API builds. Enterprise clients need Spring Cloud microservices with service discovery and distributed configuration. They need Kafka or RabbitMQ message queuing for event-driven architectures. They need JVM tuning and database performance optimisation when an application is under real enterprise traffic volumes. They need legacy Java 8 or Java 11 systems migrated to Java 21 or 25 LTS in stages that do not destabilise live production environments. Our senior Java developers and architects have worked on all of these scenarios.
We sign a non-disclosure agreement before receiving any project information. Client identity, scope, API design, database architecture, and commercial terms are all covered. No KiwiCommerce reference appears in any Java package, class, Javadoc comment, Maven or Gradle configuration, or project documentation your client receives. Your agency's name is on every deliverable. Ours is not, at any stage.
3+ Experience Years
Spring Boot REST APIs with proper layering, JPA and Hibernate, Spring Security, Bean Validation, and OpenAPI documentation. Java written to production standards — tested, documented, and structured so your client's future developer can work with it without needing a guided tour.
5+ Experience Years
Complex Spring Boot backends for enterprise clients. Spring Cloud microservices, event-driven architecture with Kafka or RabbitMQ, and the test coverage that enterprise Java production environments require. Comfortable with the operational complexity of multi- service Java system.
5+ Experience Years
Spring Cloud microservices service discovery, distributed configuration, circuit breaking, and API gateway. For agencies with enterprise clients building independent, deployable Java services rather than a monolithic backend. Architecture documented for the client's own team to continue confidently.
4+ Experience Years
Java concurrency, Collections, Streams, generics, records, sealed classes, and virtual threads. For agencies with client projects where raw Java performance and language depth matter more than framework abstraction batch processing, libraries, and performance- critical backend components.
6+ Experience Years
Assesses Java 8 and Java 11 codebases honestly, documents what is there, and executes the upgrade to Java 21 or 25 LTS in stages. For agencies whose clients are on unsupported Java versions and need a clear, risk-managed migration path rather than an emergency rebuild.
7+ Experience Years
Sets the architecture. Joins client technical calls as your agency team. Makes the Spring configuration and database decisions that determine long-term maintainability. Manages junior developers on the project. For agencies that need senior Java direction alongside delivery capacity.
Java 25 LTS (September 2025) and Java 21 LTS are our production targets. Java 26 (March 2026) is non-LTS with only six months of support not for production. We advise agencies clearly when a client's existing Java system needs migrating away from Java 8 or Java 11.
Every Java developer is UK-based. Enterprise Java decisions service boundary design, Spring Security configuration, legacy migration strategy require direct, real-time discussion. Your agency gets that discussion during the working day, not via a message left overnight.
Spring Boot 4 (supporting Java 25) and Spring Framework 7 (November 2025) are our current framework releases. Spring Framework 6.2.x open source support ends June 2026. We build to the current Spring generation not to older patterns that quietly accumulate technical debt in new applications.
We write Spring Boot applications with documented API contracts, clear package structure, and Javadoc that makes sense. Your agency can present the codebase to a client's technical leadership without pre-explaining every architectural decision made during development.
Signed before briefing. Covers client identity, scope, class naming conventions, API design, database schema, and commercial terms. No KiwiCommerce reference in package names, Javadoc, project documentation, or any deliverable. Each project carries independent NDA coverage.
Fixed-price for a defined Java project. Monthly retainer for ongoing enterprise accounts. Senior Java architect embedded into your sprint cycle for a sustained engagement. We structure the commercial model around how the project needs to work.

You brief us on the Java project Spring Boot API, microservices, legacy Java system, or enterprise backend. We build in staging you access throughout. All deliverables carry your agency name. IP transfers on delivery. No direct client contact unless you direct us onto a technical call as your team member.
Java 25 LTS (September 2025) and Java 21 LTS are our standard production versions. Spring Boot 4 and Spring Framework 7 (November 2025) are our current framework releases. We do not build production systems on Java 26 (non-LTS) or Spring Boot 2.x, which is no longer maintained.
Yes. We review the existing codebase before agreeing a migration scope covering code quality, test coverage, dependency status, and breaking changes in the target Java version. We execute the migration in stages, validating behaviour before and after each step. We do not agree a timeline without reviewing the codebase first.
We sign before receiving any project or client information. The NDA covers client identity, scope, package and class naming, API design, database schema, and commercial terms. No KiwiCommerce reference in any Java file, Javadoc, Maven or Gradle configuration, or project documentation at any stage.
