What is this app
A university administrative management system designed for 15,000 students to efficiently view class schedules and classroom locations. Students can submit assignments through a dedicated portal with a 30-day retention policy, perform pre-class attendance check-ins, and interact with an AI-powered chatbot for policy inquiries and school-related matters. The system streamlines academic operations by centralizing attendance tracking, assignment workflows, and student support.
As a student, I want to view my class schedule and classroom locations so that I know where to go.
As a student, I want to submit my assignment files through the system so that I can meet my deadlines.
As a student, I want to check in for attendance before class so that my presence is recorded.
As a student, I want to chat with an AI assistant to quickly find answers to school policy questions.
As a teacher, I want to view and download student assignment submissions for grading.
As a teacher, I want to monitor class attendance records to track student participation.
As an administrator, I want to upload and update course schedules and policy context for the AI.

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
A university system with 15,000 students requires SSO for secure, organization-level account management, which is a PRO feature.

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 project description of 15,000 students, we estimate an additional 1,000 faculty members and 100 administrative staff for a stable campus ecosystem.
University administrative systems are typical stock migration systems where the academic year's data is fully loaded and active from the start. We assume the system maintains a full year of records for scheduling and attendance, justifying the maximum value.

Peak load
We assume the most intense system usage occurs during the 5-minute window before the start of major class blocks. With 4 major time slots per day over 20 school days per month, we estimate 80 occurrences. This scene focuses on the heavy write load of attendance check-ins.
