What is this app
A university management platform serving 15,000 students, enabling them to view class schedules with classroom locations, check in for attendance before class, and submit assignments. The system includes an AI policy assistant to resolve administrative inquiries and features an automated 30-day assignment file retention policy for efficient resource management.
As a student, I want to view my class schedules and classroom locations so that I know where to go.
As a student, I want to check in before class so that my attendance is recorded.
As a student, I want to submit assignments through the system so that I can meet my deadlines.
As a student, I want to talk to an AI chatbot about university policies so that I can get answers quickly.
As a teacher, I want to create assignments and view student submissions so that I can manage the course.
As an admin, I want to manage student and teacher accounts to ensure system access.

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 identity management, which is a feature exclusive to 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.
The school has approximately 15,000 students. We add roughly 1,000 teachers and 100 administrators/staff to arrive at a total stable user base of 16,100.
University administrative systems are typically stock migration systems where data for all students and courses is present from the start of the academic year. Therefore, we use 365 days to represent a fully loaded annual cycle.
Class Start Peak
Deadline Concurrency Rush
Standard Campus Day Activity
88
times/month
We assume 4 major class start times per day on 22 weekdays per month (88 occurrences). The 300-second duration represents the typical 'grace period' before and after the bell where students are most likely to trigger the check-in system simultaneously.
Main impact: Peak Concurrency
