A few dollars and an evening against thousands and weeks. They are mostly not competing for the same apps — and the best outcome is often to use one to brief the other.
| AI App Builder | Developer / agency | |
|---|---|---|
| Simple app (4–6 screens) | Free – $15 in credits | $1,500 – $25,000 |
| App with backend and payments | Screens: $15 – $40; backend needs a developer | $6,000 – $80,000+ |
| Time to first version | Same day | 3 weeks – 4 months |
| Changes afterwards | Minutes, cents | Hourly rate or change requests |
| Exact design reproduction | No | Yes |
| Complex backends, real-time | Out of scope | Yes |
| You own the code | Yes, exported | Usually, per contract |
| Publishing | You, with a guide | Often included |
| Main risk | You test and publish yourself | Overruns; paying to discover the idea needs changing |
If the app is screens-and-data — most small business, community, education and personal apps — the AI builder is the whole answer. If it is mostly backend, payments at scale or regulated data, hire — but build the AI prototype first and hand it over as the brief.
Describe it in a sentence, watch the screens appear, tap through them on your phone. Free to start — 100 credits, no card, no code.
