Why migrate off Lovable?

Three common reasons: investor diligence requires portable code, a price change makes the platform uneconomic, or you're hiring engineers who want a conventional stack. All three tend to hit around the Series A stage. Moving off Lovable while the app is still small is meaningfully cheaper than moving off it later.

How long does a Lovable → Next.js migration take?

Four to six weeks for a standard app with Supabase, Stripe, and auth. Multi-app agency migrations run 8–12 weeks as a retainer. The timeline is driven by integration count and user migration complexity, not by the size of the codebase.

$9,999 fixed fee for a single-app Platform Escape, including the audit, code migration, data migration, integration rewiring, Vercel deploy, and two weeks of post-cutover support. Agency retainers scoped separately.

Will my users notice?

Ideally no — downtime targets are under 15 minutes during cutover. Authentication typically requires a passwordless re-verification email on cutover day; users re-verify and keep their data. No password resets, no forced account recreations.

Can I keep my Lovable UI?

Usually yes. Lovable generates Next.js + Tailwind; the UI layer ports cleanly to a standard Next.js project. We keep every pixel unless the founder wants cleanup, and that cleanup is scoped separately.

What do I need to prepare before starting?

Access to your Lovable project, your Supabase project, your Stripe account, your DNS registrar, and your OAuth providers (Google, GitHub, etc.). We'll request each on day zero. You don't need to prepare the code — we handle the export and cleanup.

Is this the same as the Platform Escape service?

Yes. Platform Escape is our name for any off-platform migration (Lovable, Replit Agent, Base44, Bolt). The scope and pricing are the same; the specifics of the source platform determine where the work is concentrated.

What happens after the migration?

You own the code, in your git repo, deployed to your Vercel account, with data in your Supabase project. You can keep working in Cursor, hand off to an engineer hire, or move to Ongoing Maintenance with us. We include two weeks of post-cutover support in every migration.

Migrate from Lovable to Next.js — plan

Why non-technical founders migrate

Three patterns show up in 2026 migration conversations:

Investor diligence.Lead investors at Series A ask “can we see this running off Lovable?” There is no good answer except “yes, here's the repo.” See the Replit Agent case study for the same dynamic on another platform.
Price changes.Credit billing that drifts, surcharges, or a platform pricing announcement that changes the app's unit economics. The Bluefinch — Base44 agency escape to Next.js is a worked example at agency scale.
Hiring. The first engineer you hire wants a repo, a test suite, and standard tooling. Migration is the prerequisite for hiring engineers who stay.

The escape plan, end-to-end

The 4-week plan. Agency multi-app retainers scale the same structure across more weeks.

Week 0 — audit and architecture

Export the Lovable project; clone it to a fresh Next.js repo on GitHub.
Map every Lovable-specific dependency to a target (Supabase Auth, Stripe, Resend, Vercel Cron).
Produce the architecture diagram, env var reference, and cutover plan.
Provision Vercel, Supabase production + staging, domain in DNS provider.

Week 1 — data and auth

Export Supabase schema to migrations (Supabase CLI), apply to staging.
Write and test RLS policies on every table (pgTAP in CI).
Stand up Supabase Auth or Clerk; design the re-verification email flow.
Start dual-write from Lovable's Supabase to the new Supabase project.

Week 2 — integrations and deploy

Rewire Stripe: server-side keys, signed webhook, idempotent handler, reconciliation cron.
Wire Resend: SPF, DKIM, DMARC, transactional templates.
Port every external integration (analytics, CRM, file storage).
Vercel preview deploys; test every unhappy path.

Week 3 — cutover

Final data sync: seven days of dual-write reviewed, any discrepancies resolved.
Cutover window: schedule at the lowest-traffic time. Typical downtime: 5–15 minutes.
DNS flip to Vercel. Re-verification emails sent to all active users.
Monitor for 48 hours. Fix edge-case issues as they surface.

Week 4 — handoff

Decommission Lovable deployment after a two-week overlap period.
Handoff doc: architecture, env vars, runbooks, prioritised backlog.
Transfer ownership of Vercel project, Supabase project, domain, Stripe webhook.
Two weeks of post-cutover support begin; on-call windows documented.

The four decisions that matter most

Decision	Default we recommend	When to deviate
Auth provider	Supabase Auth	Clerk if you need multi-tenant orgs out of the box
Cutover window	Saturday, 04:00 local time	Weekday if your users are B2B with weekday usage
Dual-write duration	7 days	14 days for regulated industries (fintech, healthtech)
Keep editing Lovable during migration	No — freeze at week 0	Only critical bug fixes, mirrored manually

What founders most commonly get wrong

Trying to migrate and ship new features simultaneously. Freeze Lovable edits at week 0. Exceptions (critical bug fixes) must be mirrored to the new codebase the same day.
Underestimating auth migration. Passwordless re-verification is the lowest-friction cutover pattern, but it requires email deliverability to be rock-solid by cutover day. Start email deliverability setup in week 0.
Forgetting OAuth redirect URLs. Every OAuth provider (Google, GitHub, etc.) has a list of authorised redirect URIs. Update these in week 2 at the latest; changes can take up to an hour to propagate.
Not running a reconciliation diff. The seven-day dual-write period is the safety net. Compare rows nightly; fix translation bugs before cutover.

What the migration does not include

UI redesigns. We port the Lovable UI as-is. Redesign is a separate engagement.
New features. Anything outside the current app scope is quoted separately.
Long-term engineering staffing. Two weeks of post-cutover support are included; beyond that, move to Ongoing Maintenance or hire in-house.

How to start

Book the free rescue diagnostic. We'll look at the Lovable project on the call, confirm scope, and provide a written cutover plan and fixed-fee quote inside 24 hours. If you already know Platform Escape is the right scope, skip to the App Migration service page and start the engagement from there.
