a meal-planning app for subscribing households
PROJECT OVERVIEW
What this app does
A paid meal-planning web app for households that saves household size, preferred grocery store, and food allergies. Subscribers describe what they want to eat over the next two weeks, and the app creates a dinner schedule, consolidates it into a shopping list, and looks up real prices at their local supermarket.
As a visitor, I can create an account and begin a paid subscription so that I can use the meal-planning service
As a subscriber, I can save my household size, preferred grocery store, location, and food allergies so that plans reflect my household
As a subscriber, I can describe what I want to eat over the next two weeks so that the app can generate a dinner plan
As a subscriber, I can view the generated dinner schedule and consolidated shopping list with local supermarket prices
As a subscriber, I can review my subscription status and payment history
As a subscriber, I can review my previously generated meal plans

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 $99/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 100 registered subscribers because the description explicitly states that the service has about 100 users per month, and the explicit figure is the most reliable scale anchor. This treats the figure as the stable monthly subscriber population rather than anonymous traffic. If your actual business operations differ, such as 100 new subscribers joining every month in addition to retained accounts, this parameter can be adjusted accordingly.
We assume 225 equivalent days because a consumer subscription web app commonly grows gradually through its first year rather than launching with a full pre-existing dataset. This follows the standard linear-growth SaaS pattern. If your actual business operations differ, such as an established customer base being imported at launch or a recent marketing-driven burst, this parameter can be adjusted accordingly.

Peak load
We assume household planning is concentrated into a two-hour weekly period because meal selection and grocery preparation commonly occur on weekends or before a regular shopping trip, but individual households are not synchronized to one exact minute. The scenario therefore uses a flat two-hour window and occurs four times per month. Generation, history browsing, and opening an existing plan are separated into distinct purposes because they have different trigger volumes and intended core actions even when they happen during the same planning period. If your actual business operations differ, such as daily meal planning, the duration and frequency can be adjusted accordingly.
