PROJECT OVERVIEW
What is this app
A course and attendance system for a university: students view their timetable, check in for class, submit assignments, and ask an AI
assistant about campus policies; teachers schedule classes, set assignments, and review submissions and attendance; admins maintain
the policy documents the AI draws on.
As a student, I can browse the catalog and enroll in courses.
As a student, I can watch course videos and track my progress.
As a student, I can submit assignments and view my grades.
As a teacher, I can upload and manage courses.
As a teacher, I can grade assignments and give feedback.

COST BREAKDOWN
Requirements → minimum viable version → 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
Multi-client shared backend plus single-tenant isolation require at least the PRO tier.

Infrastructure cost is unavoidable
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.
Vibe-coding speed + a production-grade backend
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.
SCALE & SIZING
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.
