The short answer
An MVP web application typically costs $25,000 to $90,000 and takes six to twelve weeks to build. The low end is a lean product with sign-in, one or two core workflows and an admin view. The high end adds payments, several integrations, AI features or compliance requirements.
The biggest factor is not the technology. It is how many distinct workflows and user roles you put into the first version.
Where the money goes
| Phase | Share of effort | What happens |
|---|---|---|
| Product definition | 10–15% | Agree the core workflows, user roles and what is deliberately left out |
| Design | 10–20% | User flows, wireframes and screens built on a component library |
| Core build | 40–50% | Front end, back end, database, authentication and business logic |
| Integrations and AI | 10–20% | Payments, email, third-party APIs and any AI features |
| Testing and launch | 10–15% | Automated tests on critical paths, staging, production deploy and monitoring |
Integrations and AI features are the most variable lines. An app that only stores and displays its own data is predictable. An app that syncs with a CRM, takes payments and extracts data from uploaded files has more ways to fail, and each needs handling.
No-code, low-code or custom
| Approach | Best for | Watch out for |
|---|---|---|
| No-code builder | Testing demand quickly with simple logic | Platform limits, per-user pricing, harder migration later |
| Internal tool builder | Admin panels and back-office apps for staff | Not designed for public, customer-facing products |
| Custom code | Complex logic, AI features, integrations, compliance, products you plan to grow | Higher upfront cost and a longer first release |
We are happy to recommend no-code when it fits. Our comparisons of Bubble vs custom development and Retool vs custom internal tools cover where each side wins.
How to keep the cost down
- Cut to one core workflow. Write down the single job a user must be able to complete, build that well, and move everything else to a later list.
- Use a proven stack and component library. Custom design can come after you know which screens matter.
- Delay integrations you can fake. A weekly CSV export or a manual step can stand in for an integration until volume justifies building it.
- Add AI where it does real work. Features like extracting data from uploaded documents can replace hours of manual entry. AI added for its own sake adds cost and testing without changing the outcome.
- Decide quickly. Slow feedback on designs and builds stretches timelines, and timelines drive cost.
How Lumeor prices MVPs
We scope each MVP as a fixed-price project after a short discovery call, with a written list of workflows, roles, integrations and what is out of scope. Builds are delivered in your accounts and repository. Related work includes Ovarra, an AI copyright and DMCA automation SaaS.
