What is this app
A comprehensive administrative platform for universities enabling 15,000 students to manage class schedules, submit assignments, and record attendance digitally. The system features an AI-powered policy chatbot to provide instant answers to student inquiries and provides faculty with tools for grading and monitoring attendance. This solution streamlines academic operations while maintaining assignment files for a 30-day retention period.
As a student, I want to view my class schedule and classroom locations so that I can attend classes on time.
As a student, I want to check in for attendance via the system before class so that my attendance is recorded accurately.
As a student, I want to submit my assignment files through the portal so that faculty can grade them.
As a student, I want to chat with an AI assistant about school policies so that I can get instant information without visiting an office.
As a faculty member, I want to grade student assignments and provide feedback so that students know their performance.
As an administrator, I want to manage the class schedule and locations so that students and teachers have up-to-date information.

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.

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.
Per the project description, there are 15,000 students. We estimate an additional 1,000 faculty members and 100 administrative staff for a total pool of 16,100 users.
We assume this university system is a brownfield launch or migration from an existing paper/legacy system. Since it serves a fixed student body throughout a 12-month academic cycle, the system is fully loaded from day one. Therefore, the effective value is set to the maximum to account for a full year of data accumulation.

Peak load
We assume a scenario where the entire student body attends classes synchronized by a bell system. This creates a 5-minute (300 seconds) window of intense activity at the start of major lecture slots. With 4 class transitions per weekday and 22 weekdays per month, we estimate 88 occurrences. This scenario is isolated to capture the maximum concurrency spike for attendance check-ins.
