What is this app
A comprehensive administrative platform for universities managing 15,000 students. It centralizes course scheduling, classroom locations, and digital assignment submissions while automating attendance tracking through a check-in system. An AI-powered chatbot provides instant support for campus policies, ensuring streamlined communication and operational efficiency.
As a student, I want to view my class schedule and classroom locations so that I can attend my classes on time.
As a student, I want to check in for attendance via the system so that my presence is recorded.
As a student, I want to submit my assignments digitally so that I can meet deadlines.
As a teacher, I want to view and download student submissions so that I can grade their work.
As a teacher, I want to create assignment requirements for my classes.
As a visitor, I want to ask an AI chatbot about university policies so that I get instant answers.
As an admin, I want to manage student and teacher accounts to ensure system security.

Requirements to minimum viable plan to cost
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.

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 ≈ $441/mo at AWS list prices, often more), plus the extra dev and ops staff. Momen bundles all of it into $368/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.
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.
The project description specifies 15,000 students. Based on typical higher education ratios, we estimate approximately 1,000 faculty members and 50 administrative staff are required to manage the student body, totaling 16,050 users.
This university system is a typical institutional management platform. We assume a 'brownfield' scenario where the system starts with a full student and course database. Since the school functions continuously, we set the value to 365 days to reflect a fully loaded annual data state.

Peak load
This scenario represents the high-intensity bursts occurring 4 times a day on weekdays when students arrive for classes. We assume a 5-minute (300 seconds) synchronized window for these check-ins. With 22 weekdays per month and 4 blocks per day, we set occurrences at 88.
