What a web application costs at each level
The same six-feature app on Web app, built to four different standards. Every other answer is held constant so the only thing changing is depth.
| Level | Cost range | Timeline | Hours | Team |
|---|---|---|---|---|
| MVP Prove it works | $160K – $220K | 3.7 – 5.1 months | 1,350 | 7 |
| Standard Production ready | $230K – $320K | 4.4 – 6 months | 1,975 | 7 |
| Advanced Built to grow | $300K – $420K | 5.1 – 6.9 months | 2,575 | 7 |
| Enterprise Audited and integrated | $410K – $550K | 5.8 – 8.1 months | 3,425 | 7 |
Fragmentation and release overhead
Four browsers across desktop and mobile viewports.
Device & OS test matrix
34 hrs
12 configurations across 4 OS versions. This is QA, and it is unavoidable.
Project setup
32 hrs
Build configuration, signing, platform conventions — before the app does anything.
No app store
0 hrs
No review queue and no submission process. You can ship a fix in minutes, which is a genuine and underrated cost advantage.
Web app is the right call
- Ship a fix in minutes with no review queue
- Linkable, indexable and reachable from any device
- Usually the cheapest way to validate a product idea
Reconsider when
- You need background location, push on iOS at full fidelity, or offline-first behaviour
- Your users expect to find you in an app store
Adding Web app to an existing build costs much less. As an additional surface it multiplies client hours by 0.72 rather than 0.98, because the backend, data model, API contracts and design system are already paid for. See how platform mixing works.
