a personal task manager for large user bases
PROJECT OVERVIEW
What this app does
A personal task manager app for a registered user base of 1,000,000 people. Users can create, view, filter, edit, complete, and delete their own tasks through a focused dashboard and task detail experience.
As an anonymous visitor, I can review the app entry page and create an account
As a task user, I can view and filter my personal tasks
As a task user, I can create a personal task
As a task user, I can review and update a task's details or completion state
As a task user, I can delete a personal task
The following user counts are projected totals after one year of growth
1000
anonymous_visitors
Public visitors who can review the welcome page and begin account registration.
1000000
task_users
Registered users who create, view, edit, complete, and delete their own tasks.
COST BREAKDOWN
How your requirements become a plan and a price
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
BASIC
A production task service for real users requires multiple workflows, ongoing publishing, and professional external branding, requiring at least the BASIC plan.

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 $175.67/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 ≈ $331.72/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 population of 1,000,000 because the project description explicitly states that user scale, which takes priority over category-based defaults. Anonymous visitors are tracked separately and are not included in this registered-account figure. If the stated figure represents active users rather than total registered accounts, this parameter can be adjusted accordingly.
We assume 225 effective accumulation days because a consumer task-management application normally follows a standard linear-growth pattern during its first mature year rather than launching with a full pre-existing dataset. If the million accounts and their historical tasks are imported at launch or growth occurred in a concentrated recent burst, this parameter can be adjusted accordingly.
Daily Task Activity

times/month
7.18 req/s
Peak load
We assume registered task activity is spread across a 16-hour daily period because personal planning occurs throughout waking hours and is not pulled into the application by a shared external signal. The scenario recurs every day, so it has 30 monthly occurrences and a duration of 57,600 seconds. Reviewing, capturing, editing, and deleting are separated into independent purposes because their participant volumes and intended core actions differ. If usage is concentrated into a shorter morning or evening window, the duration and participant allocation can be adjusted accordingly.
