PROJECT OVERVIEW

What this app does

这是一个面向固定批发客户的雨伞选品网站，约200位客户每天使用它浏览和挑选商品。网站维护约2000个SKU，每个SKU配有多张商品图片，并提供商品目录与详情查看能力；内部商品经理负责新增和更新SKU及图片。

作为批发客户，我可以按SKU、名称或分类浏览和筛选雨伞商品，以便找到候选商品

作为批发客户，我可以查看单个SKU的资料和多张图片，以便比较并完成选品

作为商品经理，我可以新增雨伞SKU并上传多张商品图片，以便建立可供客户浏览的目录

作为商品经理，我可以查看并更新现有SKU资料和图片，以便保持选品目录准确

The following user counts are projected totals after one year of growth

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

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 $47.75/mo all-in above.

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 ≈ $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.

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

205

Total users

我们假设系统包含用户明确给出的200个批发客户账号，并为日常维护约2000个SKU配置一个约5人的内部商品管理小组，因为小型批发目录通常由少量员工持续维护。稳定运营时的注册账号规模按205个处理；如果200这个数字已经包含内部员工，或实际只有一名管理员，可相应调整。

275

Data retention period

我们假设该网站会在客户账号和约2000个SKU准备完成后较快进入稳定使用，因为固定批发客户每天选品通常属于早期集中上线、随后使用量趋于平稳的业务模式。因此采用早期增长后进入平台期的等效数据积累周期；如果实际是从零逐月拓展客户和SKU，可相应调整为更短的线性增长周期。

Core business scenarios

Morning Customer Selection

times/month

0.36 req/s

Peak load

We assume the busiest customer activity occupies a two-hour morning period every day because wholesale buyers commonly conduct product research during an early working session, without a single external signal forcing everyone to arrive at once. The period is therefore modeled as a broad 7,200-second window rather than a short synchronized burst, and it occurs on all 30 days because the blueprint states that the customers use the private catalog daily. The purpose is kept focused on customer product comparison and is not combined with internal catalog maintenance. If customer access is limited to weekdays or driven by a narrower buying deadline, the frequency and duration can be adjusted accordingly.
