Your Vibe-Coded App Works. Here's the Runbook to Move It Into a Repo You Own — Before You Have To

Two-way GitHub sync makes it look like you already own the code. You mostly do — but the platform is still the source of truth, your secrets aren't in the repo, and your database might not leave with you. Here's the exact eight-step migration, in the order that doesn't break production.

The takeaway

You vibe-coded an app on Lovable, Replit, Bolt, or Emergent, it has real users, and now you want it in a Git repo you control. On the leaders you already can: Lovable does two-way GitHub sync on your default branch — every prompt becomes a commit in your repo — and on paid plans you export the full project and own the code outright, deployable to Vercel, Netlify, AWS, or your own box. The catch is that 'synced' is not 'migrated.'
The single biggest trap is secrets. Environment variables and API keys are NOT carried across an export or import — Replit's own docs say they must be re-added by hand — so a repo that builds locally will still fail in production until you re-create every secret in your new host's environment. Treat the secret inventory as step one, not an afterthought.
The second trap is the backend. If your app leans on the platform's bundled database, auth, or storage, the code comes with you but the data and the managed service may not. Stand up your own Postgres/managed DB and move the data deliberately before you cut hosting over.
The order that avoids downtime: connect GitHub and confirm the repo is the source of truth, get a clean local build, inventory and re-create secrets, provision your own database, wire a minimal CI (lint + typecheck + test), deploy to your own host in parallel, move DNS, then decommission the platform. Do it while the app is healthy — the worst time to learn your secrets didn't transfer is during an outage or an acquirer's security review.

At a glance

What actually moves vs The trap if you skip it — compared at a glance
Migration step	What actually moves	The trap if you skip it
Connect GitHub / export	Full source code, commit history on the leaders	'Download-only ZIP' platforms give you a dead snapshot with no sync — verify export type first
Re-create secrets	Nothing — env vars and API keys do NOT transfer	App builds locally, 500s in production; the #1 post-migration outage
Provision your own database	Your schema and code, but not always the managed DB or its data	Silent lock-in — the app still phones home to the platform's backend
Wire CI	Nothing — the platform never gave you lint/typecheck/tests	Regressions the vibe-coding loop used to catch now ship straight to users
Deploy to your own host	The built app, on infra you control	Downtime if you flip DNS before the new deploy is verified green
Decommission the platform	Your monthly bill, once everything else is proven	Paying twice, or worse, deleting the source of truth before the mirror is real

The one-line version: on the leading vibe-coding platforms you can already put your app in a GitHub repo you own — but "synced to GitHub" is not "migrated off the platform." The code moves cleanly; your secrets and often your database do not. Do the move in the right order, while the app is healthy, and you never take downtime. Skip a step and you learn — usually in production — that a repo which builds on your laptop still can't serve a request.

If your app is on Lovable, it's likely already mirrored: Lovable's native GitHub integration is a two-way sync on your default branch, so every prompt you send becomes a commit in your repository, and every push you make to GitHub flows back in. On paid plans you export the full project and own the complete source, deployable to Vercel, Netlify, AWS, or your own server. Replit, Bolt, and Emergent offer their own paths to GitHub. The runbook below is platform-agnostic; it's the order that matters.

1. Connect GitHub and confirm the repo is the source of truth#

If you haven't already, connect the platform's GitHub integration and let it create (or push to) a repository under your account. Then verify it's real: clone the repo to your machine, not the platform's editor.

git clone https://github.com/you/your-app.git
cd your-app

If you get the whole tree with a commit history, you have a live mirror. If the platform only offers a download-only ZIP, that's a dead snapshot — note it, because it changes step 6 (you'll have no ongoing fallback).

2. Get a clean local build#

Install and run it locally against nothing but the repo. It will almost certainly fail — that's the point of doing this now.

npm install
npm run build   # or the framework's dev command

Whatever it complains about — a missing env var, a hardcoded platform URL, an SDK that assumes the platform runtime — is a migration task. Write each one down.

3. Inventory and re-create your secrets — this is the step everyone skips#

Environment variables and API keys do not transfer. They live in the platform's secret store, and your .gitignore correctly keeps .env out of Git, so the export cannot include them. This is the number-one cause of "it built, why is it 500ing."

Grep the code for every variable it reads at runtime:

grep -rhoE 'process\.env\.[A-Z0-9_]+' src | sort -u

That's your checklist. Re-create each one in your new host's environment (Vercel/Netlify project settings, a secrets manager, or a local .env you never commit):

# .env  — never commit this; it stays in .gitignore
DATABASE_URL=postgres://...
STRIPE_SECRET_KEY=sk_live_...
OPENAI_API_KEY=sk-...

Rotate any key that was ever visible in the platform's client bundle while you're here.

4. Provision your own database before you touch hosting#

If your app uses the platform's bundled database, auth, or storage, the code comes with you but the data and the managed service may not. Stand up your own — a managed Postgres is the usual landing spot — run your migrations against it, and move the data:

pg_dump "$OLD_PLATFORM_DB_URL" > dump.sql
psql "$NEW_DATABASE_URL" < dump.sql

Point the app's connection string at the new database and confirm it reads and writes correctly. Do this before you flip hosting, so the new deploy comes up on a backend you already trust.

5. Wire a minimal CI#

The vibe-coding loop was quietly catching some regressions for you. Once you leave, nothing does — unless you add it. A three-check pipeline is enough to start:

# .github/workflows/ci.yml
name: ci
on: [push, pull_request]
jobs:
  check:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with: { node-version: 20 }
      - run: npm ci
      - run: npm run lint --if-present
      - run: npm run typecheck --if-present
      - run: npm test --if-present

Lint, typecheck, and whatever tests exist. It's not comprehensive; it's a floor, and a floor is what an acquirer's engineer will look for.

6. Deploy to your own host — in parallel, not as a cutover#

Deploy the app to your target host (Vercel, Netlify, Fly, a container, whatever) using the secrets from step 3 and the database from step 4. Keep the platform's deployment running the whole time. Verify the new deployment against a preview URL: real login, real write, real payment in test mode. Only when the parallel deploy is green do you move traffic.

7. Move DNS last#

Point your domain at the new host. Because you verified in step 6, this is a routing change, not a leap of faith. Watch error rates for a few hours.

8. Decommission the platform — deliberately, and last#

Now, and only now, decide what to do with the platform. Two sane options: leave the two-way sync on and treat the platform as one more contributor to your repo, or make the repo the sole source of truth and stop pushing from the platform. What you must not do is keep two "sources of truth" indefinitely — that's how a platform edit silently clobbers a hand-fix. Cancel the plan once the new stack has served real traffic and the mirror is provably redundant.

The two forcing functions#

Do this while the app is boring and healthy. The two events that turn should into must are an outage — where you suddenly need to debug infrastructure you don't own — and a security questionnaire from your first enterprise buyer, who wants to see your repo, your CI, and how you handle secrets. Both are the worst possible time to discover that your secrets never transferred and your database won't leave. A vibe-coded app that reaches real users has already earned the two hours this takes. Spend them on a normal Tuesday.

Frequently asked

Do I actually own my code on a vibe-coding platform?

On the current leaders, yes — but verify it before you build anything you care about. Lovable advertises a native, two-way GitHub integration: it creates a repository for you, and every AI change becomes a commit while every push you make to GitHub syncs back into Lovable. On paid plans you export the full project and own the complete source, free to deploy on Vercel, Netlify, AWS, or your own servers. The red flag is any platform that offers only a download-only ZIP or no export at all — that's a snapshot, not ownership, and it's a reason to walk before you have real users.

Why does my exported app build locally but fail in production?

Because your secrets didn't come with the code. Environment variables and API keys live in the platform's secret store, not in the repository — Replit's import docs are explicit that secrets are not transferred and must be re-added manually. Your .gitignore correctly keeps .env out of Git, which is exactly why the export can't include it. The fix is a deliberate secret inventory: list every key the app reads at runtime, then re-create each one in your new host's environment (Vercel/Netlify project settings, a secrets manager, or a .env you never commit). Do this before you cut hosting over, or the first production request 500s.

What's the hardest part of leaving — the code or the backend?

The backend. Moving source code is a solved problem on any platform with real GitHub sync. The lock-in that bites is the managed database, auth, and storage the platform bundles: the code references them, but the data and the running service don't necessarily transfer. Before you decommission anything, stand up your own database (a managed Postgres is the common landing spot), migrate the data, repoint the app's connection string, and verify against the new backend. Cut hosting only after the new data path is proven.

Should I keep the two-way sync on or turn it off?

Keep it on until your own pipeline is real, then decide. While you're migrating, two-way sync is a safety net — you can keep prompting on the platform and still get commits. Once your own CI and host are green, you have a choice: leave sync on and treat the platform as one more contributor to your repo, or make the repo the sole source of truth and stop pushing from the platform. What you should not do is run both as 'sources of truth' indefinitely — that's how a platform edit silently overwrites a hand-fix, or vice versa. Pick one canonical source the moment you're standing on your own infra.

When is the right time to do this migration?

While the app is healthy and boring, not during a crisis. The two forcing functions that turn this from 'should' into 'must' are an outage (you need to debug infra you don't control) and a buyer's security questionnaire or SOC 2 review (an enterprise customer wants to see your repo, your CI, and your secret handling). Both are terrible times to discover your secrets didn't transfer and your database won't leave. Run the eight steps on a normal Tuesday, verify the mirror in parallel, and keep the platform as a fallback until the new stack has served real traffic.
