Next.js and other frameworks
Establish a reproducible build and start process, Node.js version, monorepo, package manager and container or server deployment.
Functions and edge runtime
Identify Vercel Functions, Edge Functions, middleware and runtime constraints and port or reimplement them appropriately.
Caching, ISR and images
Configure Next.js cache, revalidation, Image Optimization, CDN assumptions and multi-instance operation deliberately for the target.
Variables and secrets
Move production, preview and development values separately, rotate sensitive values and distinguish build from runtime configuration.
Databases and storage
Migrate PostgreSQL, Supabase, Neon, Redis, uploads and object storage with separate transfer and validation paths.
Domains and integrations
Prepare DNS, TLS, redirects, webhooks, OAuth callbacks, email and external APIs for the new environment.
Preview, staging and production
Rebuild branch deployments, separated environments, approvals, health checks and rollback around the team's workflow.
Monitoring and operations
Define logs, availability, resources, backups, updates, CVE response and ownership before cutover.
Migrate Vercel to Coolify or German and European infrastructure
WZ-IT moves Next.js and other Vercel applications into a controlled target operating model. Builds, functions, caches, environment variables, domains, data, preview workflows and ongoing operations are planned as one platform path.
Starting point
When a Vercel migration makes sense
- Hosting cost or scaling behaviour should become more predictable
- The application should run on German, European or customer-controlled infrastructure
- Vercel dependencies and US platform services should be reduced
- The team wants to keep deploying through Git without operating the target servers itself
- Application, Supabase or other backends and ongoing operations should be organised together
Replace Vercel with control
Retain Git-push and automated deployments while reducing platform dependency deliberately
A Vercel migration is not a repository import. The target must reproduce the runtime, data and delivery capabilities in use and then operate them reliably.
Capture Vercel dependencies
Framework, builds, functions, edge runtime, middleware, cron jobs, caches, domains, integrations and environments are inventoried.A target that fits the application
Coolify, Docker or Kubernetes is sized on German, European, customer-controlled or on-premises infrastructure.A tested changeover
Staging, data transfer, user journeys, DNS switch and rollback point are validated before Vercel is retired.

Open Vercel migration guideVercel migration path
Map every Vercel layer relevant to the application
Next.js officially supports operation as a Node.js server or container. The additional target architecture depends on the Vercel capabilities and scaling assumptions actually in use.
Effort factors
Not every Vercel application has the same portability
- Number of projects, repositories, domains and environments
- Vercel-specific edge, cache, analytics and integration capabilities
- Number and complexity of functions, workers and cron jobs
- External backends, databases, storage and their data volume
- Code changes required for runtime, state or scaling
- High availability, global distribution and particularly short cutover windows
Process
Inventory Vercel, test the target environment and switch deliberately
The production Vercel environment remains available until the application, data paths and operating capabilities have been accepted on the target.
- 01
Capture the Vercel project
Document code, settings, environments, functions, domains, integrations, data and current usage.
- 02
Build the target platform
Deploy runtime, delivery, data services, reverse proxy, TLS, backups and monitoring.
- 03
Test staging and data
Deploy the application, validate functions and user journeys, and rehearse data transfer or synchronisation.
- 04
Execute cutover
Move final data, switch DNS and integrations, run smoke tests and maintain the rollback window.
What we need for initial assessment
- Vercel projects, repositories, frameworks and environments in use
- Functions, middleware, cron jobs, caches and other Vercel capabilities
- Databases, storage, integrations and broad sizes
- Domains and intended staging and production structure
- Target preference, maintenance window and desired operations after migration
Entry price
Vercel migration from €1,990 excl. VAT
€1,990 excluding VAT is the entry price for one clearly bounded application. The binding proposal follows a technical assessment of Vercel capabilities, data, target platform and cutover requirements.
The entry price is not a blanket package. Where the target is unclear or platform coupling is deep, the PaaS Exit Review from €1,490 excluding VAT may be the right first step.
All prices are net and exclude statutory VAT. The offers are addressed to businesses.
Individually assessed Vercel migration
For the controlled move of a bounded Vercel application to a prepared target environment.
Factors that determine price
- Number of projects, services and environments
- Functions, edge runtime, cache and preview logic
- Database, storage and transfer volume
- Code and architecture changes required
- Target platform, availability and security requirements
- Testing, cutover and operating scope
Related paths
Secure the target decision, backend and operations together
Depending on the current state, the path starts with an exit review or moves directly to the target platform, backend migration and ongoing operations.

Next.js, Coolify, European infrastructure, functions, data and operations
- A Vercel migration starts at €1,990 excluding VAT. The entry price is not a fixed blanket scope. Projects, functions, data, storage, required code changes, target architecture and cutover determine the specific proposal.
- Next.js officially supports operation as a Node.js server or Docker container. Multi-instance operation, caching, ISR, streaming, Image Optimization and Vercel-specific integrations still require deliberate target configuration.
- No. Coolify is a self-hostable deployment platform. Hetzner is one possible infrastructure provider on which Coolify or another target model can run. WZ-IT can also use other German, European, customer-controlled or on-premises infrastructure.
- We inventory every function, runtime and dependency. Node.js-compatible functions can often move into the application or separate services. Edge-specific APIs, regions or runtime constraints may require adaptation or an alternative component.
- Yes. Branches, builds, domains, variables, data access and approvals can be rebuilt as preview, staging and production paths on the target platform. Scope and isolation are agreed in advance.
- The target environment is tested in parallel. Data transfer, DNS, TTL, final synchronisation, smoke tests and rollback point are planned before cutover. Possible downtime depends particularly on data volume and write activity.
- Yes. WZ-IT can operate the target infrastructure, Coolify or another platform, monitoring, backups, updates and incident response. Software maintenance and development are agreed as a separate application scope.
Reviews & projects
Migrations with measurable business impact
Cloud exit, Proxmox and sovereign operations with concrete results instead of architecture slides.
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.
