"How much does it cost to build an app?" has no single answer because there are four very different ways to build one. Here is the honest comparison.
The short answer
AI builders and no-code are cheapest and fastest but hit a ceiling. Freelancers are mid-range for contained work. Agencies cost the most and deliver a full build. A product simulation sits in between: a flat fee for a real, owned, runnable foundation you can take anywhere.
The comparison
| Option | Typical cost | Speed | You own the code? | Best for |
|---|---|---|---|---|
| AI builders | $20 to $50 per month | Hours to days | Usually no | Fast tests, simple apps |
| No-code | $300 to $3,000 per year | Days to weeks | Usually no | Internal tools, simple SaaS |
| Freelancers | $25 to $100 per hour | Variable | Yes | Well-defined, contained work |
| Agencies | $40,000 to $250,000+ | Months | Yes | Complex, long-lived products |
How to choose
- Just testing demand? AI or no-code. Spend almost nothing to learn.
- One contained feature, clear spec? A freelancer.
- A complex product you will run for years? An agency, or start with a foundation that de-risks it.
- Want speed and ownership without an open-ended contract? A product simulation: a documented, runnable foundation for a flat fee, that any team can build on.
The cost nobody lists
The biggest hidden expense is the rebuild. Choosing the cheapest tool, then outgrowing it and rebuilding on real code, often costs more than building it right the second time would have on its own. Factor in the full life of the product, not just the sticker price.

Frequently asked
Which option is cheapest?
AI builders and no-code are cheapest upfront, often $20 to $300 per month. But cheap upfront can become expensive over time if you outgrow the tool and have to rebuild on real code.
Which gives me something I own?
Custom development and a product simulation give you a real, owned codebase. No-code and AI builders often keep you on their platform, which is fine until you need to leave.
