Build an app yourself or hire a team? The comparison

For simple standard apps without custom logic, an app builder for roughly €10 to €100 a month is often enough — you don't need an agency for that. Custom development from €15,000 pays off as soon as your own processes, integrations with your systems, or requirements on data protection and performance come into play. In between sit AI tools and freelancers.

Route 1: app builder (no-code) — the cheapest start

Builders assemble apps from ready-made blocks — without a line of code, on a subscription from roughly €10 a month.

  • What it covers: info apps, menus, appointment booking, simple forms — standard cases that a ready-made block covers.
  • Where it ends: your own business logic, connections to ERP, CRM or specialist applications, offline mode with sync, particular data-protection requirements, store-grade performance.
  • The hidden price: your app lives on the provider's platform. If prices rise or the service shuts down, there is no code to take with you.

Route 2: AI tools and vibe coding — fast to a prototype

AI tools today generate runnable app prototypes from a description — good for testing an idea before money flows. For running a business app day to day, three things are usually missing: someone who understands and maintains the generated code; security and data protection at a provable level; and a clean connection to your systems. Our advice: an AI prototype as an idea test, yes — as a production system only with developers who take responsibility for the code.

Route 3: freelancer — flexible for small projects

An experienced freelancer (hourly rates typically €80–150 in the DACH region) fits when the project is small and well defined and someone in-house can judge the work technically.

  • Strengths: lower costs than an agency, a direct line, a quick start.
  • Risks: availability over the years (maintenance!), knowledge tied to one person, design, backend and testing rarely in one hand.

Route 4: agency or software company — responsibility for the result

From around €15,000 project volume, a team covering development, design and project management takes over — with a contract, acceptance criteria and operation after launch. That is the usual route once the app is part of your value creation: customer accounts, system integration, data protection, scaling. What to check when choosing: the 12-point checklist.

The cost comparison over three years

The entry price misleads — the routes only become comparable over time. A sample calculation over three years for the same use case:

  • Builder: at roughly €30 a month, about €1,100 over three years. In return: no code of your own, no export, features and prices set by the platform provider. For standard cases still unbeatably cheap.
  • Freelancer: say 200 hours at €100 = €20,000 for the build — maintenance over the years is the open flank: is the person available when the autumn OS update breaks something?
  • Agency/software company: a simple app from around €30,000 plus maintenance (rule of thumb 15–20 % a year) ≈ €43,000–48,000 over three years. In return: your own documented code, plannable maintenance, one accountable contract partner.
  • The real question: not “what does the start cost?” but “what is there after three years?” — a subscription without substance, or a system you own and can extend.

Three cases, three routes

  • Restaurant with a menu and reservations: a standard case that builders cover out of the box — builder, decided in an afternoon.
  • A founder testing a market idea: first an AI or design prototype for feedback from real prospects, then a custom MVP once the idea holds.
  • A mid-sized company connecting field service to its ERP: own processes, integrations, offline mode, data protection — agency or software company, chosen with the checklist.

The decision guide in four questions

Four questions lead to the decision — for the full picture of costs, process and provider choice, see the guide:

  • Does a ready-made block cover your case? → Builder. Then you don't need us.
  • Do you first want to know whether the idea holds? → AI prototype or clickable design prototype, then decide.
  • Small, clear project plus technical competence in-house? → Freelancer.
  • Own processes, integrations, data protection, day-to-day operation? → Agency or software company. Entry without a big commission: Discovery for €1,900, ending in a fixed-price quote — credited when you order.

FAQ

Frequently asked questions

Can I create an app as a layperson?

Yes, with an app builder for standard cases: ready-made blocks, no code, from roughly €10 a month. The limits: custom logic, integrations, data protection — that takes developers.

What does an app cost in comparison?

Builder roughly €10–100 a month, freelancer by hourly rate (typically €80–150 in the DACH region), custom development from €15,000 for simple apps to over €100,000 for complex ones — details with a cost estimator on our costs page.

Is an AI-built app enough for production?

As a prototype and idea test: yes. For day-to-day operation with real user data it takes maintenance, security and system integration — in other words, developers who take responsibility for the code.

What if I start with a builder and need more later?

Switching usually means rebuilding, because builder apps don't hand over code. If you can foresee needing integrations or custom logic, a tightly scoped custom version is often cheaper than two attempts.
