What is this app
This university administrative management system enables 15,000 students to manage their academic life by viewing class schedules with classroom locations, checking in for attendance, and submitting assignments. It features an AI-powered customer service chatbot to handle policy inquiries and automates the cleanup of assignment files after 30 days. The system serves students, faculty, and administrators to streamline campus operations.

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 is a large-scale university system requiring organization-level SSO for 15,000 users, which is only supported in 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 university has 15,000 students. We estimate 1,000 faculty members and 50 administrative staff for a total of 16,050 users. As a closed internal system, anonymous visitors are negligible.
University management systems are typically pre-loaded with student and curriculum data before the semester starts, representing a 'migration' or 'day-one full load' scenario. Therefore, we set the effective days to 365.

times/month
This scene represents the high-concurrency moments just before classes begin. We assume 4 major class start times per day across 22 weekdays, resulting in 88 occurrences per month. The 300-second duration reflects the typical window students use to settle in and mark attendance.
