PROJECT OVERVIEW

What this app does

This product is a simple free-plan signup experience for visitors and registered users. It presents the available free plan, lets a registered user activate it, and provides a basic account status view, while administrators maintain the plan definition.

As an anonymous visitor, I can view the available free-plan information so that I can decide whether to register

As a registered user, I can activate the free plan for my account

As a registered user, I can view my current free-plan status

As an administrator, I can create and maintain the free-plan definition so that visitors see the current offering

The following user counts are projected totals after one year of growth

administrators

Internal operators who create and maintain the free-plan definition.

180

registered_free_users

Registered accounts that activate or review the free plan.

1000

anonymous_visitors

People who can publicly view the free-plan information before 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.

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 ≈ $330.25/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.

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

200

Total users

We assume a small company-site or lead-capture scale of approximately 200 registered accounts because the only stated capability is a free-plan offering, with no throughput, market size, or explicit user figure. This conservative anchor includes a small pool of free-plan users and internal administrators; if the underlying product has a broader registered customer base, this parameter can be adjusted.

225

Data retention period

We assume standard linear growth over the first year because this is a simple SaaS-style free-plan experience with no indication of a migration, seasonal launch burst, or recent-burst pattern. The equivalent operating period is therefore set to the standard linear-growth assumption; if the service launches with a full pre-existing dataset or a sharp launch spike, this parameter can be adjusted.

Core business scenarios

Routine Public Plan Discovery

Routine Free Plan Activation

0.01 req/s

Peak load

This scenario represents ordinary, unsynchronized visitor arrivals rather than a campaign or externally signaled rush. Public plan discovery is kept separate from account activation and administrator maintenance because those behaviors have different participants and purposes. The broad one-hour window represents a modest slice of daily browsing activity, and the scenario occurs daily throughout the month.
