How Much Does It Cost to Build an App in 2026? Real Numbers by Method

Building an app costs anywhere from about $16 a month to over $500,000, and the honest answer is "it depends which of four paths you take." A freelance developer runs roughly $5,000–$50,000+ for a simple build, a dev agency runs $50,000–$500,000+, a no-code platform subscription runs about $29–$549/month plus your own time, and an AI-native "vibe coding" tool like greta.sh runs from a few dollars up to a few hundred dollars a month depending on usage with hosting and maintenance either bundled in or billed separately for years afterward.

This piece is the broad reference: a real side-by-side across every build method people actually compare, including the ongoing costs most cost calculators quietly leave off. If you specifically want the deep dive on how greta.sh gets AI-native builds down toward single-digit dollar amounts, we cover that build-by-build math separately — this post is the one that answers the broader question first.

We've seen founders come in after getting wildly different estimates for essentially the same app idea, one option priced like a small side project, another like a six-month company initiative. The surprising part is often not the difference in hourly rates, but how differently each approach defines the work. That's one reason we built Greta around reducing the amount of engineering work required in the first place: if AI can handle much of the initial build, the economics of testing an app idea change completely.

What actually drives app cost

Every quote you get — whether it's $8,000 or $180,000 is really answering the same five questions:

• Complexity of the build. A CRUD app with a login screen and a list view is a different animal than something with real-time sync, video processing, or AI features baked in.
• Backend and data model. Anything with a database, auth, roles/permissions, or multi-user state adds real engineering time, whether a human or an AI agent is doing the work.
• Integrations. Payments, SMS, email, third-party APIs, and existing internal systems each add setup time and often a recurring line-item fee.
• Platform coverage. Web-only is cheapest. Native iOS + Android (or a single cross-platform codebase) adds cost on top.
• Ongoing maintenance - the part most people forget to budget. Base44's own cost breakdown and MobiLoud's build-cost analysis both put ongoing maintenance at roughly 15–20% of the original build cost, every year, for custom-built apps. That's not a one-time number, it's a recurring bill for the life of the app.

The real cost comparison table

Ranges below are pulled from Bubble's, Base44's, and MobiLoud's own published 2026 cost breakdowns (sources at the bottom) plus Greta.sh's own published pricing. Figures marked are ones we couldn't independently confirm against a live source at time of writing.

Regional freelance/agency hourly rates (for context, from MobiLoud's 2026 developer-rate breakdown): US-based developers run roughly $150–$250/hr, Western Europe $100–$180/hr, Eastern Europe $40–$80/hr, South Asia $25–$50/hr, Latin America $35–$65/hr, Southeast Asia $20–$40/hr — which is most of why the same app spec can produce wildly different quotes.

The hidden, ongoing costs people forget to price in

The sticker price of "building the app" is usually the smallest number in the total cost of ownership. Over a 3-year horizon, the numbers most guides skip:

• Maintenance: 15–20% of the original build cost, annually, for custom-built apps — so a $60,000 build can mean $9,000–$12,000/year in maintenance alone, every year it stays live.
• Hosting and infrastructure: reported in the $2,000–$15,000/year range for a mid-complexity app, scaling with usage.
• Third-party services: payment processors, SMS/email providers, analytics, AI model calls commonly $3,000–$15,000/year on top of the base build.
• App store and platform fees: roughly $124/year for standard developer account fees, before any paid distribution.
• Feature updates and iteration: ongoing product work, reported around $5,000–$30,000/year for actively maintained custom apps.
• Subscription-model alternatives bundle most of this in. MobiLoud's own 3-year cost model for a web-to-app subscription approach came out to roughly $50,864 total (about $5,000 setup plus ~$15,288/year), specifically because hosting, maintenance, and updates were folded into the subscription instead of billed separately. No-code and AI-native subscriptions follow the same logic — you're often trading a bigger one-time number for a smaller recurring one.

The practical takeaway: don't compare "cost to build" across methods without also comparing "cost to keep running for 3 years." A cheap build with expensive maintenance can cost more by year two than an AI-native subscription that bundles hosting and updates from day one.

Where Greta.sh's cost claims fit, honestly

Greta.sh sits at the low end of the AI-native column above: plain-English prompting produces a real full-stack app - frontend, backend, database, auth, and deploy without a separate line-item for each of those, and without the 15–20%-of-build-cost annual maintenance bill that custom code typically carries. That's a genuinely different cost structure than agency or freelance builds, not just a cheaper version of the same one.

It's also not a claim that every app, at any complexity, costs pennies. The honest range is: very simple, well-scoped apps can be built and hosted for single-digit dollar amounts, while more complex, integration-heavy builds cost more, just still well under the traditional-dev or even typical no-code subscription ranges in the table above. If you want the specific build-by-build breakdown behind the "apps under $10" claim, including what was and wasn't included in that number, that's covered in detail here treat this article as the wide-angle comparison and that one as the receipts.

Frequently asked questions

How much does it cost to build an app in 2026?

It depends entirely on the method. Realistic 2026 ranges run from about $5–$500/month for an AI-native build, $29–$549/month for a no-code platform subscription, $5,000–$50,000+ for a freelance developer, and $50,000–$500,000+ for a full dev agency build before ongoing hosting and maintenance, which typically add 15–20% of the build cost per year for custom-coded apps.

What's the cheapest way to build an app?

For most simple to moderately complex apps, AI-native "vibe coding" platforms and no-code subscriptions are the cheapest path, since hosting, backend management, and updates are usually bundled into a monthly fee instead of billed as separate maintenance work. A freelance developer for a very narrowly scoped app can also come in cheap, but design, hosting, and ongoing support are usually extra.

Do app cost estimates usually include hosting and maintenance?

Often not upfront. Traditional agency and freelance quotes commonly cover only the initial build; maintenance (reported at roughly 15–20% of build cost annually), hosting ($2,000–$15,000/year for a mid-complexity app), and third-party service fees are frequently billed separately afterward. No-code and AI-native subscriptions more often bundle these into the monthly price.

Is a no-code or AI app builder actually cheaper long-term than hiring a developer?

For most straightforward apps, yes, when you account for the full 3-year cost of ownership rather than just the initial build. A subscription model that bundles hosting, maintenance, and updates can come out well below a custom build once you add that build's 15–20%-per-year maintenance bill on top of the original quote. Complex, highly custom, or deeply integrated apps can still tip the math back toward custom development.
