a test utility for registered users
PROJECT OVERVIEW
What this app does
This product is a compact test utility that presents test instructions, lets registered users create test records, and allows them to review their own results. It serves people who need a simple place to run or record tests without additional specialized workflows.
As an anonymous visitor, I can view the test utility instructions
As a registered user, I can create a test record and save its result
As a registered user, I can review my own test records
The following user counts are projected totals after one year of growth
1000
registered_users
People with accounts who create test records and review their own stored results.
1000
anonymous_visitors
Visitors who can open the public utility and read its test instructions without creating an account.
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

WHY MOMEN
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 $39/mo all-in above.

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 ≈ $330.26/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 $0/mo all-in and removes the need for an ops team.
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
We assume this is a general small tool because the input contains no explicit user figure and no throughput signal. The category anchor for a small utility is used as the registered-account baseline, while anonymous visitors are modeled separately; if the test process has a stated audience or transaction volume, this value can be adjusted.
We assume this is a standard small utility with gradual adoption because the input only identifies a test product and does not describe a launch with a full pre-existing dataset or a recent burst. If the product launches with a full pre-existing dataset or experiences a sharp early surge, this parameter can be adjusted accordingly.
Routine Test Utility Use
Routine Test Utility Use

times/month
0.02 req/s
Peak load
We assume the utility is used during a broad daily period without a bell, deadline, or other external signal that would synchronize users. The scenario therefore represents routine activity across an eight-hour window, with separate purposes for anonymous instruction viewing, registered record creation, and personal-history review so incidental reads are not combined with the core action. Daily operation supports 30 occurrences per month. If usage is concentrated around a test event or deadline, a separate narrower scenario would be appropriate.
