a landing-page conversion audit tool
What this app does
This tool evaluates a landing page screenshot against a stated conversion goal, such as getting signups. An AI agent analyzes the screenshot and returns scores and written reasoning about the value proposition, call to action, and trust signals. Results are emailed through Resend, with access managed through a free-first-audit and credit-based model.

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

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 ≈ $330.29/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.
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 the throughput signal is approximately 40 landing-page audits per day, with roughly one audit submitted per visit. Applying the required recent-burst window places the registered customer base in the low-thousands order of magnitude, so we use 4,000 registered accounts for a solo-creator launch. If users routinely submit many audits or the product acquires a substantially larger audience, this parameter can be adjusted.
We assume the product is a recent-burst solo-creator launch because the stated operating pattern is a small, newly launched service with modest daily activity rather than a mature platform. The equivalent accumulation period is therefore set to 90 days. If the product later develops steady linear growth over a full operating year, this parameter can be adjusted.

Peak load
We assume this scenario isolates the main product event: registered users submitting landing-page screenshots for AI review. Submission is separated from result reading and billing because it starts an asynchronous AI and database workflow and creates the principal growing business record. We assume a five-minute operational window for the concentrated daily submission period and daily occurrence because the blueprint describes approximately 40 audit submissions per day without a stronger external synchronization signal. If submissions cluster around campaigns or scheduled reviews, the window can be narrowed.
