a lesson booking app for private students
PROJECT OVERVIEW
What this app does
This private education app lets up to 30 students browse and book lessons, pay through an integrated checkout, access documents assigned to them, and connect through a simple student community board. The administrator can manage lesson availability, review bookings and payments, assign student documents, and moderate community posts. Payment processing is the only specific external integration assumed because other integration providers were not identified.
As a student, I can browse available lessons, book one, and begin payment
As a student, I can review my lesson bookings and payment statuses
As a student, I can view and download documents assigned to me
As a student, I can read and publish text posts to connect with other students
As an administrator, I can create and update lesson availability
As an administrator, I can review student bookings and payment statuses
As an administrator, I can upload, review, and remove documents assigned to students
As an administrator, I can review and remove student community posts
The following user counts are projected totals after one year of growth

WHY MOMEN
Your options for this project
In the table below, the 'monthly infrastructure' for the self-built / AI routes is derived from the AWS list prices shown below, sized against this project's actual usage. Figures cover infrastructure and operations only — AI usage is billed separately and excluded here, so they don't match the $99/mo all-in above.

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 ≈ $330.26/mo at AWS list prices, often more), on top of the dev and ops staff you'd need to hire. Momen bundles all of it into $0/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.
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
We assume 31 registered accounts because the requirement explicitly limits the service to 30 students and identifies one administrator. This is a private education app, so no broader consumer registration base is added. If your actual business operations differ, such as adding teachers or support staff, this parameter can be adjusted accordingly.
We assume 225 effective accumulation days because this is a new, small education application expected to add students and business records gradually rather than launching with a full pre-existing dataset. This follows a standard linear-growth pattern for a private service app. If your actual launch includes a full pre-existing dataset or a rapid initial enrollment burst, this parameter can be adjusted accordingly.

Peak load
We assume student activity is spread across a four-hour daily period because private learners browse schedules, check payments, retrieve files, and use the community at self-selected times rather than responding to a shared bell or release event. Separate purposes distinguish passive browsing and reading from booking and publishing so their participant scales and core actions are not overstated. The period lasts 14,400 seconds and occurs 30 times per month because student access can happen every day. If access is limited to weekdays or concentrated after scheduled lessons, these parameters can be adjusted accordingly.
