How to Migrate a Vercel Node.js App to Hostinger

Deploy a Vercel Node.js app through Hostinger’s Node.js Web App flow, restore its production settings, test it, then change domain traffic only after validation.

You can move a Vercel-hosted Node.js app to Hostinger by deploying its code through a GitHub repository or ZIP upload, restoring its production configuration, and testing it before directing your domain to the new deployment. The documented process uses Hostinger’s Node.js Web App deployment; it does not guarantee that every Vercel project or Vercel-specific feature will transfer unchanged.

Check whether your project fits this migration

Hostinger’s instructions cover Node.js applications deployed through its Node.js Web App flow. They distinguish that process from a standard website migration tool intended for traditional sites such as WordPress or static sites. Start by confirming that your app can run in the destination’s Node.js deployment environment, then identify anything it relies on beyond its source code. Hostinger’s Vercel migration guide specifically calls out Edge Functions and Vercel Blob as examples of Vercel-native features that may need alternatives.

  • Confirm the current app works before changing hosting.
  • List integrations and application paths that depend on Vercel-specific services.
  • Collect the names and correct production values of required environment variables.
  • Identify a compatible Node.js version for the project.

Do not assume the source code alone represents the full application. Authentication, databases, uploads, scheduled work, and other services may require separate configuration or replacement if they depend on Vercel-specific functionality.

Choose how to transfer the project

Hostinger documents two ways to provide the application files. Its guide recommends the GitHub route; ZIP upload is an alternative when you prefer to supply an archive.

Transfer method Best fit Trade-off
GitHub repository connection The latest project code is already in a repository, and you want to select a repository and branch for deployment. Requires the right GitHub authorization and careful selection of the repository and branch. Hostinger describes this as its recommended and fastest method; that is not a measured time guarantee.
ZIP upload The project is local or you are not using a repository connection. You must prepare the archive and upload an updated one when the project changes.

For ZIP upload, include package.json and the source files the application needs. Hostinger’s instructions say to leave out unnecessary node_modules. If you use GitHub, first push the finalized code and decide which branch should supply the deployment.

Deploy the app on Hostinger

  1. Open Hostinger’s Node.js Web App deployment flow and choose the domain for the app. A temporary domain is an option for testing before production traffic moves.
  2. Select GitHub connection or ZIP upload. For GitHub, authorize access as needed, then choose the repository and intended branch. For ZIP, upload the prepared project archive.
  3. Review the build settings and select a Node.js version compatible with the project. Hostinger highlights runtime selection for typical Next.js projects built with v0.
  4. Enter the application’s required environment variables and their production values. Hostinger can identify variable names used in source code, but it cannot supply the secret values for you.
  5. Start deployment. Hostinger says the process builds and deploys the app and provides a preview when it is complete.

Dashboard labels and available runtime versions may change. For the current deployment steps, consult the migration guide and the Node.js application guide.

Restore environment variables safely

Vercel separates Local, Preview, and Production environments, so a value used in a local run or preview may not be the value your production app needs. Check the correct production configuration rather than copying values indiscriminately. Vercel’s environments documentation explains these environment distinctions.

During deployment, Hostinger supports adding variables manually or importing a .env file. Use its environment-variable deployment instructions for the current flow. Never commit secrets to GitHub. If you need to change or add a value after deployment, Hostinger documents that process separately in its post-deployment variable guide.

Test the destination before changing your domain

Use the preview or temporary domain to verify the app before directing production traffic to it. Exercise the parts of the application that matter for your setup, including sign-in, database access, uploads, scheduled tasks, and any integrations identified during your initial review. A successful build is not by itself proof that those runtime paths work.

Do not switch the production domain until the destination has passed your checks. The destination account provides the applicable DNS records; the available migration instructions do not establish one universal record set for every domain configuration. Vercel’s CLI documentation can help inspect existing domain DNS configuration, but it is not a substitute for the records supplied by the destination account: Deploying a project from the Vercel CLI.

Keep the existing Vercel deployment available until you have confirmed that the new deployment is working after the domain change. The cited instructions do not provide a complete migration-specific rollback recipe, so plan how you would restore the prior DNS configuration using the values and access for your own domain before making the cutover.

Keep future deployments and settings in sync

Hostinger says that changes made in v0 after migration should be merged to the GitHub main branch and redeployed from the Hostinger dashboard. If you use a different branch or workflow, make sure the deployment continues to use the intended source. Environment values can also be edited after deployment using Hostinger’s post-deployment instructions.

Runtime availability and dashboard steps can change. Check the current vendor documentation before a migration; the exact DNS records, compatibility of individual Vercel features, and a universal rollback procedure are not established by the cited guides.
