What is this app
A university administrative management system designed to serve 15,000 students through centralized academic tools. It enables students to view schedules, submit assignments with a strict 30-day retention policy, and check in for class attendance, while providing 24/7 AI-powered assistance for school policy inquiries. The system streamlines interactions between students, faculty, and administrators to ensure efficient campus operations.
As a student, I want to view my class schedules and classroom locations so I know where to go.
As a student, I want to submit my assignments online so they can be graded.
As a student, I want to check in for attendance via my device to prove my presence.
As a student, I want to ask an AI about school policies to get instant answers.
As a teacher, I want to view and grade student assignments to provide feedback.
As an administrator, I want to update school policy articles so the AI remains accurate.

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 multiple workflows, an AI chatbot, and permanent hosting with a custom domain.

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 specifies approximately 15,000 students. Based on typical academic ratios, we estimate 1,000 faculty members and 50 administrative staff, bringing the total registered user base to 16,050. No anonymous access is expected for this private institutional system.
University administration systems are typical stock migration systems where data is fully loaded and usage is consistent across the academic year. Therefore, we assume the system reaches full capacity quickly and use 365 equivalent days.
