v0 quickly delivers strong React and Next.js interfaces. We add backend, data model, auth, permissions, deployment, testing and operations so components become a product.
v0 is closely integrated with Vercel: publishing creates Vercel deployments, GitHub can be connected and environment variables are project-scoped. We turn that into a maintainable product with backend, data model and a clear operations decision.
v0 often delivers strong Next.js or React interfaces. We add missing API layers, data persistence, error states, permissions and tests so UI components become an application.
If Vercel fits, we harden the workflow. If sovereign operations are required, we review portability, containerization, SSR/SSG behavior, env mapping and alternative hosting targets.
We turn chat versions into traceable releases: branches, pull requests, code reviews, CI checks and deployments that a team can operate without the v0 UI.
The risks rarely appear in the first click through the UI. They sit in data access, deployment, secrets, authorization and missing operations.
Auth, roles, row-level security, input validation and secret handling need a traceable review before real customer data is processed.
Builder hosting, Supabase Cloud, Replit deployments or Vercel workflows are convenient, but not automatically right for sovereign operations.
Production operations need Git discipline, environments, tests, monitoring, backups, updates and clear ownership - not just working screens.
Frontend, backends such as Supabase, external APIs, MQTT or IoT platforms can each work while tenant isolation, authentication or encryption between components still has gaps.
The entry point is deliberately auditable and clearly scoped. After that, we decide together whether hardening, migration, further development or operations is the next useful step.
Review code, data model, tenant isolation, secrets, dependencies and relevant data paths across frontend, backend, APIs and connected systems. The result is a prioritized action plan instead of guesswork.
Move code into a clean repository, separate environments, clarify data and auth dependencies and plan target operations.
OWASP-oriented fixes, correct permissions, secure secrets, rate limits, role model and robust validation at the critical points.
CI/CD, staging and production, tests, monitoring, logging, rollback and, for public apps, a review of rendering, sitemap, robots.txt, structured data and performance.
Co-managed development, patch and CVE monitoring, backups, uptime monitoring and incident response with a service level that can grow with user count and criticality.
Many prototypes consist of several tools. We always review the full stack, not only the visible builder.
Lovable is strong for fast MVPs with React, Vite, Tailwind and Supabase. For production, we review auth, data access, RLS, secrets, deployment, SEO and the path out of platform lock-in.
Bolt accelerates browser-based prototypes. We move the application out of the WebContainer world into a traceable repository with real persistence, environments, deployment and operations.
v0 quickly delivers strong React and Next.js interfaces. We add backend, data model, auth, permissions, deployment, testing and operations so components become a product.
Replit is practical for prototypes and small tools. We migrate code, environments, database, secrets and deployment to controlled infrastructure with monitoring and maintenance.
Base44 can create fast business apps. We review code ownership, platform dependencies, data access and maintainability, then turn it into a controllable production setup.
The exact stack depends on the project. The target state is always the same: you own the source code, deployments are traceable, data is controlled and operations are measurable.
Take over or restructure frontend and app architecture cleanly.
Review data model, RLS, auth flows and self-hosting.
SSO, roles and central identity instead of ad-hoc logins.
European hosting with controllable deployment.
Traceable builds, staging, production and rollback.
Uptime, logs, updates, vulnerabilities and operations under control.
Your team can keep programming with AI and contribute changes through Git. Automated builds, tests and deployments move approved versions to staging and production. Depending on scope, WZ-IT operates the infrastructure and platform, monitors dependencies and CVEs, manages backups and monitoring, and responds under a service level aligned with criticality.
Clearly defined audit
The Production Readiness Audit covers auth, data, security, tests, deployment and operations and delivers a concrete action list.
For professional secrecy holders
When a prototype will be used by law firms, healthcare organisations or other professional secrecy holders, WZ-IT connects production readiness, target architecture and managed operations.

Provider-specific answers about Lovable, Bolt, v0, Replit, Base44, self-hosting, security and operations.
Often yes, if the generated Next.js or React code remains portable. We review Vercel dependencies, serverless functions, environment variables, image handling, routing and build behavior before deciding on self-hosting.
v0 often delivers strong interfaces. For production, we add backend, data model, auth, roles, validation, error states, tests, CI/CD, monitoring and a clear hosting strategy.
Yes. We review repository structure, component quality, dependencies, build process, Next.js configuration, environments and missing backend boundaries. Then we turn it into a normal development and release process.
Most v0 projects start as frontend or component bases. A production app also needs data model, auth, permissions, API layer, validation, tests, monitoring and operations.
We first define domain logic and data flows. Then we choose fitting building blocks such as PostgreSQL, Supabase, Authentik, Keycloak or a custom API and connect them cleanly to the frontend.
We review which Vercel features are actually used, such as serverless functions, edge runtime, analytics, images or environment variables. Then we decide whether porting, containerization or hardening Vercel is the right path.
If v0 is used with Next.js, SSR, SSG and clean metadata, SEO can work well. We still review canonicals, sitemap, structured data, performance and indexable content per project.
Yes, if build, runtime and framework features fit the target operations model. We review Node version, rendering mode, API routes, assets, secrets and deployment before migrating to own infrastructure.
Yes. We start with an audit, review current operations and then plan a low-risk transition with staging, backups and rollback options.
Not automatically. The goal is controlled takeover first. We only rebuild where security, maintainability or scaling truly require it.
Yes. After hardening, we can continue developing the application, connect APIs, add AI features or integrate it into existing processes.
Typical targets are European providers such as Hetzner or your own server environment. Hybrid setups are also possible depending on requirements.
“WZ-IT moved our studio infrastructure from decentralised individual devices to a central platform: every site is securely connected via VPN, new devices are onboarded automatically and an entire site is provisioned from a template, without manual steps on location. What impressed me most is the breadth and depth of their knowledge: Timo and Robin are not a typical IT provider who sets up a server and leaves. The two of them think their way into highly complex infrastructure and software topics, work through every requirement we put in front of them, and build networking, provisioning and operations so that everything fits together in the end. WZ-IT is an excellent partner for complex software, network and architecture projects.”
Steve Kirchner
Managing Director, nextGYM GmbH
“Professional, honest and technically thoroughly sound: WZ-IT set up our Proxmox and backup infrastructure securely and future-proof. The consulting from Timo and Robin was objective and needs-driven, the implementation smooth and the final documentation exemplary. You can tell immediately that business-critical infrastructure is thought through holistically from the outset here and implemented with clear ownership.”

“Communication with WZ-IT was open, friendly and professional from the very beginning. Mr. Wevelsiep and Mr. Zins responded to every one of our questions patiently, promptly and respectfully, and contributed their own suggestions and good ideas on how to modernize our server infrastructure and adapt it even better to our needs. Throughout, WZ-IT consistently kept our need for data sovereignty and GDPR compliance in mind. Even short-notice adjustments and change requests from our side were implemented quickly and patiently and integrated consistently into the overall concept. From planning to the final handover, every step was documented transparently and comprehensively - so if a provider change should ever become necessary, the documentation would let us onboard a successor into our infrastructure very quickly. We are extremely satisfied with WZ-IT and hope to continue working together for a long time.”
