How to connect Lovable to Vercel

Use GitHub as the bridge

Vercel works best when it deploys from a Git repository. For a Lovable project, that usually means connecting Lovable to GitHub first. Once the generated code is in GitHub, Vercel can import the repository, detect the framework, run the build command, and create deployments automatically whenever the production branch changes.

Before importing into Vercel

Check the repository before connecting it. Make sure the latest Lovable code is synced, the project has a package file, the app builds locally or in Lovable, and there are no obvious secrets committed to the repo. If the app uses Supabase, Stripe, OpenAI, email, or analytics, list the environment variables you will need in Vercel.

• Lovable project is synced to GitHub
• Repository has the latest code
• Build command is known
• Required environment variables are listed
• Secrets are not committed to GitHub
• Main branch is the intended production source

Import the project into Vercel

In Vercel, create a new project and import the GitHub repository. Vercel usually detects common frameworks such as Next.js automatically. Confirm the framework preset, install command, build command, and output settings. For most Next.js apps, Vercel's defaults are often correct, but you should still check before deploying production.

Add environment variables

Environment variables are often the difference between a successful build and a broken app. Add Supabase URLs and keys, analytics IDs, Stripe keys, email provider keys, AI API keys, and any other required settings in Vercel's project settings. Use production values for production and preview values for preview when possible. Do not commit secret values into the repository.

Deploy a preview first

Deploy the project and test the Vercel preview URL before connecting your main domain. Click through every page, form, login flow, payment flow, and integration. Check mobile layout. Confirm server routes work if the app has them. If the preview fails, inspect the build logs and environment variables before changing DNS.

Connect the production domain

After the preview works, connect the domain in Vercel. Follow Vercel's DNS instructions and wait for SSL to issue. Then test the live domain, including redirects, canonical URLs, sitemap, forms, analytics, and important user journeys. Keep the previous deployment available until the Vercel domain is stable.

Copy-ready Lovable prompt

Prepare this Lovable project for Vercel deployment. Check GitHub sync, framework type, package scripts, build command, environment variables, Supabase settings, Stripe or payment settings, analytics, domain requirements, preview deployment tests, production domain steps, and rollback plan. Produce a checklist for importing the project into Vercel safely.

Common Vercel deployment issues

Common issues include missing environment variables, wrong build command, unsupported assumptions from the generated app, dependency errors, case-sensitive file paths, and integrations configured with old callback URLs. If a build fails, read the first real error in the build log. Do not only look at the final failure line.

Why Vercel is useful for Lovable projects

Vercel gives Lovable projects a serious deployment workflow. You get preview URLs for changes, production deployments from GitHub, environment variable management, domain setup, build logs, and rollback options. This is especially helpful when the project is moving from prototype to client site, startup MVP, or production web app.

Vercel launch checklist

Use this checklist before calling the Vercel deployment finished.

• GitHub repository is connected
• Preview deployment builds successfully
• Environment variables are configured
• Forms and integrations are tested
• Production domain and SSL work
• Rollback path is understood

Example Lovable to Vercel flow

A typical flow starts in Lovable with a working website or app draft. You connect the project to GitHub and confirm the repository has the latest code. Then you import that repository into Vercel, let Vercel detect the framework, and add required environment variables. The first deployment creates a preview URL. You test the preview, fix any build or runtime issues, and only then connect the production domain. This sequence keeps the live website stable while you move from Lovable Cloud or local preview to a production Vercel workflow.

Rollback and maintenance

Once Vercel is connected, keep the workflow disciplined. Do not push unreviewed experiments directly to the production branch. Use preview deployments for larger changes. Keep a note of required environment variables and third-party callback URLs. If a new deploy breaks, Vercel and GitHub together make it easier to identify the commit, roll back, or fix the missing setting without rebuilding the whole project.
