Using
Momen · full-stack no-code platform
to build
an AI room redesign app for homeowners
PROJECT OVERVIEW
What this app does
This app lets people create an account, upload a photo of a room, and receive four AI-generated redesign versions in different styles. Each version includes an estimated renovation cost and itemized price breakdown, and the completed package is available in the app and emailed to the user.
As an anonymous visitor, I can learn about the room redesign service and create an account
As a registered user, I can upload a room photo and request four AI redesigns in different styles with renovation cost estimates
As a registered user, I can review my completed redesign images and itemized renovation estimates
As a registered user, I can receive the completed pictures and price breakdown by email
The following user counts are projected totals after one year of growth

registered_users
Account holders who upload room photos, request AI redesigns, receive completion emails, and review results.
COST BREAKDOWN
How your requirements become a plan and a price
Momen doesn't give a vague quote: it first sizes the project's actual demand for each capability and resource, then costs each item out. The numbers in the 'Project demand' column below — their scale assumptions and derivations — are detailed in Scale & sizing
Multiple AI and email workflows require at least the BASIC plan.

Your options for this project
In the table below, the 'monthly infrastructure' for the self-built / AI routes is derived from the AWS list prices shown below, sized against this project's actual usage. Figures cover infrastructure and operations only — AI usage is billed separately and excluded here, so they don't match the $144.83/mo all-in above.

Infrastructure cost is unavoidable
Servers, databases, traffic and storage are inherent infrastructure costs for this project — you pay them whether you outsource, use Cursor or Lovable, or build it yourself (self-built runs ≈ $330.67/mo at AWS list prices, often more), on top of the dev and ops staff you'd need to hire. Momen bundles all of it into $100/mo all-in and removes the need for an ops team.
Vibe-coding speed + a production-grade backend
The frontend can be generated with AI tools (Cursor, Lovable, etc.); the hard part is the backend — auth, database, scaling, data security and ops. Momen delivers a production-grade backend as a BaaS: keep the vibe-coding speed on the frontend, while the backend runs on proven infrastructure — reliable, with no self-hosting or ops.
SCALE & SIZING
What scale this estimate assumes, and how the numbers are derived
Cost depends heavily on usage volume. First see the key assumptions and business scenarios this estimate uses, then the full calculation derived from each scenario for every resource — all adjustable to your real situation
4500
Total users
We assume a registered pool in the order of four to five thousand accounts because the stated throughput is about twenty room-photo requests per day, a standard growth window is appropriate, and this consumer service is likely to have roughly one request per customer. If your actual customers redesign several rooms or return frequently, the distinct registered-account estimate can be adjusted downward accordingly.
225
Data retention period
We assume 225 effective accumulation days because this is a consumer AI generation product with steady, standard growth and no indication of a full pre-existing dataset or a sudden recent launch burst. If your actual adoption reached its current daily volume very early or only surged recently, this parameter can be adjusted accordingly.
Daily Visitor Acquisition
We assume completed-result reviews are concentrated within a six-hour post-work and notification-response period because users commonly return after processing finishes or after seeing the completion email. This is still a weakly assembled period rather than a synchronized burst, so its duration is the full 21,600-second window. It occurs daily and is separated from submission because its purpose is media-rich review rather than generation. If completion emails are sent in a batch or results are viewed throughout the entire day, the window can be adjusted accordingly.
