How Much Does It Cost to Turn a Lovable MVP Into a Production-Ready SaaS?

The number you want does not exist as a clean sticker price. Agencies will still give you one. A $7,499 fixed finish. A $10,000 median. A $3,000 to $28,000 table with twenty unnamed engagements. Those are sales pages wearing a spreadsheet.

What you are actually buying is a production pass on an app that already exists. Preview works. A few people clicked around. Now you need to know what it costs to take real payments, keep other people's data off the public API, and deploy without living inside a builder login.

That is the search behind how much does it cost to productionize a Lovable app, and the cousin queries: how much to finish a Lovable MVP, how much to fix a vibe-coded SaaS, freelancer vs agency for an AI-built product.

Stop asking what Lovable costs. Ask what production costs.

Lovable's own security docs draw a hard line: the frontend is always public and must never be trusted, Edge Functions handle auth and payments, and row-level security has to be reviewed before you publish. Hosting credits on a Lovable plan are not the same job as making those three layers hold when strangers show up.

I already wrote when you should hire and why these apps break once real users arrive. This article is the buying question that comes after: what the work is, what it should cost, and how to refuse a rewrite dressed up as a productionize engagement.

There are three different jobs hiding inside one quote

If a developer cannot tell you which of these they are selling, they are guessing. You will pay for the guess.

1. The week-one audit

This is a scoped inspection, not a rebuild. Someone who has shipped production SaaS opens the live domain, the Supabase project, the Stripe account, and the Git remote. They write down what is actually broken.

A useful audit answers four questions in writing:

• Can a second account sign in on the live domain and stay signed in after refresh?
• Can an anonymous or second user read another user's rows?
• Does a live invoice.paid webhook unlock the product, or only a test event?
• Does the company own the GitHub repo, or does the product live in one founder's builder account?

If the audit cannot name those four surfaces, it is a vibe check. Do not pay senior rates for a vibe check.

2. The hardening pass

This is the job most founders actually need. Keep the product. Fix the trust boundaries. Leave the offer and the screens alone unless they block a real user.

Hardening is not a redesign. It is not a Next.js migration because someone on Twitter said Webflow is dead. It is the work Lovable already told you belongs off the public frontend.

On payments, that means verified live webhooks, not a client-side success page. I wrote the diagnostic for test mode that lies and live mode that fails. On data, that means RLS deny tests, not a dashboard that looks private. Supabase RLS is where vibe-coded SaaS gets dangerous. On keys, Supabase's current docs are blunt: the publishable key is taped to the front door. The secret key, and the legacy service_role key, bypass RLS and must never ship in a browser.

3. The rewrite

Buy this last. Rewrite when the data model cannot express the product, when generated files cannot be changed without the app collapsing, or when the deploy path cannot be owned. Do not rewrite because the buttons are ugly. Do not rewrite because the freelancer prefers another stack.

What the current SERP is selling, and what it is not

Search the phrase and you will see vendor pages, not independent cost studies. That is useful. It tells you the market is commercial. It does not tell you what your repo needs.

Links for the claims above: Appycodes cost write-up, Revex 2026 pricing guide, Afterbuild Finish My MVP. I am not endorsing any of them. I am showing you what Google currently ranks when a founder types the money question.

A better way to price the work

The U.S. Bureau of Labor Statistics May 2025 Occupational Employment and Wage Statistics survey puts the national median for software developers (SOC 15-1252) at $65.38 an hour, $135,980 a year. That is employed wage, not loaded cost, not freelance, and not an agency blended rate. It is a floor for what senior production time is worth in the U.S. market. Anyone quoting $25 an hour to harden auth and live Stripe is not doing that job, or they are learning on your users.

Use time on the four surfaces, then add a buffer for the mess the audit finds.

If you want a single founder-facing rule: pay for the audit first. Then buy the hardening pass against a written list. Do not buy a month of hours and hope production appears.

What a week-one productionize SOW must include

Put this in the statement of work. If they will not sign it, keep looking.

1. Live-domain auth: sign up, sign in, refresh, password reset, and a second user on an incognito window. No localStorage-as-security.
2. RLS deny tests: every sensitive table enabled, plus a recorded attempt where user B cannot read user A's rows. Screenshot or query log, not a verbal 'should be fine.'
3. Secret-key check: no service_role, sb_secret, Stripe secret, or model API key in the browser bundle or a public repo.
4. Live Stripe: publishable live key, webhook signing secret, idempotent handler, and a real invoice.paid that updates the workspace. Test cards do not count.
5. Ownership: GitHub org the company owns, two-way sync or export from Lovable, and a deploy path that does not require the founder's personal builder login.
6. A written leftover list: what is still unsafe, what is product work, and what is out of scope.

Lovable documents export and GitHub sync. Use that. The builder account should not be the only copy of the company.

What you should refuse to buy in the first SOW

• A redesign of screens that already convert enough to get users.
• A stack change to Next.js, Remix, or anything else before the four surfaces are proven.
• Unlimited hours with no definition of done.
• A full-time hire to move buttons while the offer is still unproven.
• A security report that only reruns the builder's own scanner and never tests with two accounts.

Agencies love process. Founders need outcomes. The outcome here is: strangers can pay, they only see their own data, and you can ship without begging a vendor for export.

How to read a quote in ten minutes

Ask the person selling the work to answer these on the call. Write the answers down.

• Which of the three jobs is this quote? Audit, harden, or rewrite?
• What is done, in one paragraph a nontechnical cofounder can repeat?
• What happens if the audit finds a leaked secret key on day one?
• Who owns the repo and the Supabase project at the end of the week?
• Will I still be able to prompt in Lovable after you leave, or did you trap the product in a private stack?

If they start with a moodboard, they are selling design. If they start with a new framework, they are selling comfort. If they start with auth, RLS, webhooks, and Git, they understand the job.

My take

Vibe coding is legitimate. Ship fast before the offer is proven. The moment users, money, or private data show up, the cost of being wrong jumps. That is when you stop treating production as another prompt.

The cheapest productionize pass is the one that does not rewrite a product people already want. The expensive pass is the one that buys a new stack because the first developer was bored.

I would rather take over an existing Lovable, Bolt, v0, or Cursor repo, prove the four surfaces, and leave you a company-owned Git remote than sell you a prettier demo. Clients do not hire me to write code for its own sake. They hire me to remove the technical risk that is blocking revenue.

What I would do this week if this were my MVP

1. Export or sync the repo into a company GitHub org before anyone else touches features.
2. Rotate any key that ever sat in frontend code. Assume it is public.
3. Run two-account RLS tests on every table that holds user content.
4. Fire one live Stripe event and watch whether the workspace actually unlocks.
5. Write a one-page SOW that names those four surfaces and nothing else.

If you cannot do those five things yourself, that is the hire. Not a redesign. Not a fractional CTO theater engagement. A production engineer who will own the messy layer and keep shipping.
