a lesson booking portal for private students
PROJECT OVERVIEW
What this app does
A private student portal for up to 30 students to browse, book, and pay for lessons, access shared documents, connect through a student community and directory, and open configured integration links. The owner uses administrative views to manage student access, lessons, bookings, payments, documents, community content, and integration resources.
As a student, I can browse available lessons, book one, and begin payment
As an administrator, I can upload documents for all students or a specific student
As an administrator, I can review and moderate student community posts
As an administrator, I can configure integration links for students or administrative use
As a student, I can review my lesson bookings and payment statuses
As a student, I can access documents shared with me
As a student, I can publish posts and comments in the student community
As a student, I can browse the active student directory
As a student, I can access integration links made available to students
As an administrator, I can create student accounts and control their access
As an administrator, I can create and maintain bookable lessons
As an administrator, I can review student bookings and payment statuses
The following user counts are projected totals after one year of growth
30
students

1

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 a registered ceiling of 31 accounts because the project explicitly allows up to 30 students and appears to have one owner acting as administrator. If additional teachers or administrators will use the app, this parameter can be adjusted accordingly.
We assume 275 equivalent accumulation days because a private app capped at 30 students is likely to reach its small cohort ceiling early and then operate at a steady plateau. If adoption is gradual throughout the year or the app launches with a full pre-existing dataset, this parameter can be adjusted accordingly.

Peak load
We assume personal lesson review, document access, community activity, directory browsing, and integration-link use are weakly assembled behaviors spread across a four-hour daily period. They share a time window but are separated into distinct purposes because their participant counts and intended actions differ. A 14,400-second window and 30 monthly occurrences represent routine daily use; if student access is concentrated around scheduled classes, the duration can be adjusted accordingly.
Main impact: Peak Concurrency
