What is this app
This university administrative management system enables students to manage their academic life by viewing class schedules, classroom locations, and submitting assignments. It features a digital attendance check-in system for every class and an AI-powered chatbot to assist students with school policy inquiries. The system is designed for high-concurrency university environments with automated data retention policies for student submissions.
As a student, I want to view my class schedules and classroom locations so that I can arrive at class on time.
As a student, I want to check-in for attendance before class starts so that my attendance record is accurate.
As a student, I want to submit my assignment files through the system so that I can meet academic deadlines.
As a student, I want to chat with an AI assistant about school policies so that I can get immediate answers to administrative questions.
As a teacher, I want to view student attendance and assignment submissions so that I can track class progress and grade work.
As a teacher, I want to create new assignments and class schedules so that my students know what to do and when to attend.
As an administrator, I want to manage school policy data and user accounts to ensure the system remains current and secure.

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.
Minimum viable plan
PRO
The project requires SSO login for university-wide account management of 15,000 students, which is only available starting from the PRO plan.

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.
Based on the requirement for 15,000 students, we estimate 1,000 teachers and 100 administrative/IT staff members to support operations, totaling 16,100 users.
University administrative systems are typical stock migration systems where student records, course catalogs, and historical attendance data are maintained throughout the academic year. Since the system operates at a stable load once the semester starts, we assume 365 days of effective data accumulation to represent a full operational cycle.

Peak load
This scenario represents the high-concurrency surge at the start of standard university lecture slots. We assume 4 main class start times per day across 22 weekdays per month (88 occurrences). The 300-second duration reflects the narrow window of the 'class bell synchronization' where students must check in to be marked present.
