Migration

How to Migrate a Lovable App to Cursor and Own Your Code

Cursor does not import a Lovable project directly. The path runs through GitHub: export your code, clone the repo locally, then open the folder in Cursor. The win is ownership — you read and approve every diff instead of letting an AI rewrite files unseen. Here is what carries over, what you set up yourself, and how to do it safely.

How do I get a Lovable app into Cursor?

Cursor has no Import from Lovable button, and there is no direct connector. The only supported path is through GitHub: you export your Lovable project to a repository, then clone that repository to your machine and open the folder in Cursor. Cursor is a code editor, so it works on files on disk — not on a hosted Lovable project.

The sequence is: connect Lovable to GitHub and push, clone the repo with git, then run Open Folder in Cursor. Once the folder is open, Cursor indexes the files and its AI can read and edit them locally. From that point Lovable is no longer in the loop unless you choose to keep using it in parallel.

In Lovable, open Project Settings → GitHub → Connect and Push to create the repository.
Copy the repo URL, then run: git clone https://github.com/<your-username>/<repo-name>.git
cd <repo-name> and confirm the files are present with: ls or git status
In Cursor, choose File → Open Folder and select the cloned repository.
Run npm install, then npm run dev to confirm the app builds before you change anything.

What carries over from Lovable and what does not?

Lovable pushes your application source — React components, the Vite config, your Supabase client code, package.json, and the lockfile. What does not travel is anything Lovable injected at build time or stored on its side: environment variables, the managed Supabase connection, edge-function secrets, and deploy configuration. You rebuild those yourself, which is exactly the ownership you are migrating for.

The code is portable; the platform plumbing is not. That is normal for any export from a hosted builder. The table below maps each piece so you know what to expect before the first build in Cursor — and so a missing env var or absent path alias does not read as a broken app when it is really a setup gap.

Lovable to Cursor — what carries over
Item	Carries over via GitHub?	What you do in Cursor
React components and pages	Yes	Edit directly — nothing to reconfigure
Vite config and package.json	Yes	Run npm install to restore node_modules
Lockfile (package-lock.json)	Yes	Use npm ci for a reproducible install
Supabase client code	Yes	Works once env vars are set in .env
Environment variables (VITE_*)	No — Lovable-side only	Recreate them in a local .env file
Supabase managed connection	No — credentials are Lovable-side	Point .env at your own Supabase project
Edge function secrets	No — stored in the platform	Re-add via Supabase dashboard or secrets manager
Deploy config and domain	No — Lovable hosts it	Set up your own host (Vercel, Netlify, Cloudflare)

How do I open the project in Cursor and run it?

Open Cursor, choose Open Folder, and select the cloned repository. Cursor reads the files on disk and indexes them for its AI. Before you run anything, create a .env file from the Supabase credentials you copied out of Lovable, then run npm install and npm run dev. Cursor edits files locally — nothing changes until you save and you approve it.

Create a .env file in the project root with VITE_SUPABASE_URL=https://<your-ref>.supabase.co
Add VITE_SUPABASE_ANON_KEY=<your-anon-key> and any other VITE_ variables from Lovable Project Settings → Environment.
Confirm .env is listed in .gitignore so you never commit keys.
Run npm install (or npm ci to match the lockfile exactly).
Run npm run dev and open the URL Vite prints — usually http://localhost:5173.
Test one Supabase read and a sign-in to confirm env vars are loaded.

Never commit your .env file. If you accidentally push it to GitHub, rotate your Supabase anon key in the Supabase dashboard immediately — a pushed key is a public key.

How does Cursor stop the AI from silently rewriting my files?

This is the real reason teams move to Cursor. In Lovable, a single prompt can touch dozens of files at once, and the changes land before you can review them — the failure mode behind context rot at file 6-7, where the AI loses track of architecture after editing six or seven files. In Cursor you read every proposed diff and click Apply, so nothing changes without your approval.

Cursor surfaces AI edits as a diff you accept or reject per hunk, and every change is a real git commit you can revert. That review gate is what prevents the Bug Doom Loop — the Lovable cycle where each Fix attempt spends a credit, generates new file changes, and often introduces a second error while resolving the first. In Cursor, a bad suggestion costs you a glance, not a credit and a regression.

It also kills false-fixed hallucination — the case where an AI announces the issue is fixed when the error has merely moved. In Cursor you run the build yourself, read the actual output, and only commit when it passes. The AI does not get to declare victory on your behalf.

Commit a clean baseline immediately after the app builds in Cursor. Then every AI edit is one reviewable diff away from a known-good state — git revert, not a credit-burning re-prompt, is your undo button.

What do I need to set up myself after the move?

Cursor replaces the editor, not the platform underneath. Your Supabase project, auth, and database still exist exactly as before — Cursor just edits the code that talks to them. The pieces you now own are the four things Lovable handled invisibly: environment variables, a deploy target, a CI check, and version control discipline. Set these up once and your project is fully self-hosted.

These map directly to The 5 Production Gaps that catch most exported Lovable apps — missing env vars, no CI, no error monitoring, untested auth origins, and absent deploy config. None are difficult on their own. The cost is doing them on purpose instead of trusting a platform to hide them. A migration specialist sets all four up correctly and verifies them in production before you cancel Lovable.

Env vars: create .env locally and add the same VITE_ variables to your host's environment panel.
Deploy target: connect the GitHub repo to Vercel, Netlify, or Cloudflare and configure the build command (npm run build) and output dir (dist).
CI check: add a GitHub Actions workflow that runs npm ci && npm run build on every push.
Git discipline: work on branches, open PRs for non-trivial changes, and keep main deployable.
Supabase origins: add your new deploy domain to Supabase → Authentication → URL Configuration.

What should I check before I migrate a broken app?

Stop the bleeding before you migrate. If your Lovable app is mid-break — a failing build, a blank screen, the Bug Doom Loop where each Fix attempt spends a credit and adds a new error — export the last working checkpoint, not the broken state. Cursor will happily open broken code; it just will not magically fix a structural problem Lovable created.

In the Lovable project timeline, find the last version where the app built and ran, revert to it, confirm the pop-out deployed build loads, then push that clean state to GitHub. Migrating a known-good build means the only variables in your first Cursor run are env vars and host config — not a pre-existing bug you now have to debug in an unfamiliar editor.

If the export itself fails or the build only breaks on a clean npm ci, that is a structural signal a migration specialist should handle. The goal is to land in Cursor with a build that passes, so your team can move forward instead of inheriting a broken app in a new tool.

What NOT to do: do not migrate a broken build hoping Cursor fixes it. Revert to a working checkpoint in Lovable first, confirm it loads, then export. A clean migration starts from a clean state.

Frequently asked questions

Can Cursor import a Lovable project directly?

No. Cursor is a desktop code editor and has no direct Lovable connector or Import from Lovable option. The supported path is to export your Lovable project to GitHub first, then clone that repository and open the folder in Cursor. The GitHub step is what gives you a real copy of your code that lives on your machine and in your own repo.

What carries over from Lovable to Cursor?

The application source code carries over: your React components, the Vite config, package.json, the lockfile, and your Supabase client code. What does not carry over is anything Lovable stored on its side — environment variables, the managed Supabase connection string, edge-function secrets, and deploy settings. You recreate those in a local .env file and in your new host. That separation is normal and is the point of owning your code.

How does Cursor stop the AI from rewriting files without me knowing?

In Lovable, the AI applies edits across many files automatically, often before you can review them — which is how context rot at file 6-7 silently breaks things. In Cursor, the AI proposes a diff and waits for you to click Apply. You see exactly which lines change in which files and you approve each one. Nothing is rewritten without your explicit confirmation, which is the ownership most teams are migrating for.

What do I need to set up myself after moving to Cursor?

You set up four things Lovable handled invisibly: a local .env file with your Supabase URL and anon key, a deploy target such as Vercel or Netlify, a basic CI check that runs the build on every push, and normal git branch discipline. None of these are hard individually; the work is doing them deliberately instead of relying on a platform to hide them.

Will my Supabase database and auth still work after migrating to Cursor?

Yes, fully. Cursor edits files on your disk and pushes through git like any developer would — Supabase, your database, and your auth are untouched by the move. The only thing that changes is where you write code. Your existing Supabase project keeps running; you simply point your local .env at the same credentials Lovable was using.

Does moving to Cursor stop the Lovable credit costs?

Cursor itself does not consume Lovable AI credits — it runs on its own subscription and your machine. That is a real saving: every change you make locally is free of Lovable credit cost. You will pay for a Cursor plan if you want its premium AI models, and you still pay Supabase and your host. But the per-prompt credit meter that drives Lovable bills up stops mattering once you have moved.

Can I keep using Lovable while I test the Cursor version?

Yes. Cloning to your machine and opening in Cursor does not touch the Lovable project — it stays exactly where it is until you choose to stop paying for it. Many teams run both in parallel for a week: they verify the Cursor copy builds, deploys, and passes auth and payment tests, then cancel Lovable. Keep Lovable until your new deploy is proven in production.

What usually breaks on the first build in Cursor?

The most common breakages are missing environment variables, a missing path alias for the @ import, and Supabase auth origins that do not include your new domain. These are configuration gaps, not code damage — the same five production gaps that catch most exported Lovable apps. Each has a known fix, and none of them mean your code is broken; they mean the platform was hiding setup you now own.

Do I need CI, or is Cursor enough on its own?

Either works, but a real CI check is worth the ten minutes. Add a GitHub Actions workflow that runs npm ci and npm run build on every push so a broken commit fails before it reaches production. Cursor will not catch a build break that only shows up in a clean install — CI does. This is one of the production gaps Lovable hides because it builds for you invisibly.

When should I get a professional to handle the migration?

If the export itself fails, the build was already broken in clean install, or auth and payments stop working after the move and you cannot trace why, bring in an engineer. A migration specialist exports the last working checkpoint, sets up env vars, CI, and deploy correctly, and verifies the new build in production before you cancel Lovable — so you never lose a working app to a half-finished migration.
