How much does it cost to build an app with AI?

That gap is the entire story of this page, and almost nobody writes about it honestly. AI builders are genuinely excellent at the first 80% of an app. The last 20% is where they stop, and the last 20% is what separates a demo from a business.

Why the tool price is not the app price

A subscription buys you generation. It does not buy you judgment, and it does not buy you the parts of software that depend on context the model cannot see.

The numbers on this are not opinion. A 2025 CodeConductor survey found 95% of developers spend extra time debugging and correcting AI-generated code. Veracode's analysis found 45% of AI-generated code introduces an OWASP Top 10 vulnerability. Those two findings are why a $25 subscription does not produce a $25 product.

What the AI reliably does well

• Screens, layout and component structure
• Boilerplate, forms, CRUD, routing
• A working demo you can show someone in a day or two
• The second and third draft of an idea, fast

What it reliably does not

• Access control. A login screen is not authorisation. API endpoints stay open to anyone who calls them directly.
• Database rules. Supabase ships row-level security off by default and AI builders often leave it off, so any signed-in user can read every other user's rows.
• Secrets. Service-role keys and API tokens end up in the browser bundle, because that is the shortest path to a working demo.
• Payments that settle. Stripe gets integrated, checkout appears to work, but with no webhook handling the app never learns whether the payment succeeded.
• Anything that has to still work in six months. No tests, no CI, no rollback.

The three costs nobody quotes you

1. Credits, burned on loops. Past a certain codebase size the model can no longer hold the project in context. It re-solves problems it already solved and contradicts its own earlier decisions. Founders routinely spend more on credits fighting one bug than the subscription costs for the month.
2. The rescue. Most AI-built apps need a human pass before launch. Budget for it up front and it is a planned $1,500 to $4,000. Discover it after a customer finds the security hole and it costs more, in money and in trust.
3. Running costs. Hosting, database, email, file storage and API calls. Small at ten users, not small at ten thousand. Almost no founder is told this number before launch, which is why Foundreco publishes a running-cost sheet before anything ships.

Cost by what you are actually building

Scope drives price far more than technology does. These are Foundreco's real starting prices, quoted fixed after a free audit, with no hourly billing.

Every number above is a starting price, and a fixed quote follows the audit. Full detail on the pricing page.

What it costs with Claude Code, Lovable, Bolt, Base44 and the rest

People search for these tools by name, so here is the honest answer per tool: the subscription is not the variable that matters. At the time of writing every major AI builder sits in roughly the same $20 to $50 per month band for an individual plan, with usage-based credits on top. Check each vendor's current pricing page for the exact figure, because they change it often.

What differs between tools is how they fail, and therefore how much the human pass costs.

A per-tool breakdown of what breaks and what it costs to fix is on the Vibe Code Rescue pages.

AI alone versus AI plus a human team

To be straight about it: if you are validating an idea, use the AI tool alone. It is the cheapest way to find out whether anyone wants the thing, and paying an agency to build something nobody wants is the most expensive mistake in this market. Bring in a team at the point where a real customer's data or money is involved.

What the rest of the market charges

Prices below were observed on 16 August 2026. They are published figures, not estimates.

Read the bottom of that table as a warning, not a bargain. At $5 to $15 an hour you are buying more of the problem from someone with no incentive to tell you the app should be rebuilt instead. And the top end is not a quality signal either: a $70,000 floor is a sales team, an office and a bench being paid for out of your budget.

What running the app costs after launch

The number founders are almost never given. Typical monthly ranges for a small live product:

• Hosting — free to about $20 at low traffic, more once you have real usage
• Database — free tier to about $25 for a small production instance
• Transactional email — free to about $20
• File and image storage — usually a few dollars until you are storing a lot
• AI features, if your app calls a model — the genuinely unpredictable line. It scales with usage, not with users, and it is the one that surprises people

Most small products land somewhere between $0 and $80 a month early on. Foundreco writes this out per project before launch, because a founder discovering their API bill after launch is a bad way to start.

Three real examples, with the client's own numbers

Every figure below was supplied by the client and measured after launch.

• Global Connectors was quoted $100,000 for an accounting ERP, and $80,000 for a stripped-down version. It built the full thing instead, and added $55,000 a year in new SaaS revenue within two months of launch.
• Petony Transportes was quoted $230,000 for a logistics ERP. It built one and grew revenue 20%.
• Havoc Motorcycles left Shopify in three days and saved $30,000 in developer fees.

How to spend the least money overall

1. Validate before you build. The most expensive app is the one nobody wanted. This is what the $800 App Blueprint exists for, and it regularly ends with "do not build this".
2. Cut scope to one job. One thing the product must do, done properly. Everything else is version two.
3. Use the AI tool for the demo. Genuinely. It is the cheapest validation instrument ever built.
4. Get a human pass before real users, not after. Planned, it is $1,500. Unplanned, after a breach, it costs more than money.
5. Insist on a fixed price and a written scope. Hourly billing transfers all the risk of a bad estimate onto you.
6. Ask what it costs to run before you sign anything.
