Summary
This is a working but tiny front-end practice project, a Frontend Mentor-style exercise built with HTML, CSS and JavaScript. It has no clear paying user, no way to charge, and nothing that stops anyone from rebuilding it in an afternoon. It has been untouched since the day it was posted.
Bloat · Not much here works or looks likely to last, yet.
Breakdown
Five measures, 100 points each. Open the receipts under any of them to see the posts and pages behind the points.
Viability
Is there a real problem, someone who would pay, and a market this builder can actually reach?
A learning exercise, not a product: age calculators are free everywhere, and nothing in the project suggests users or a way to charge.
6/100
Rubric 0–20No clear problem or user. A toy, a practice clone, or a solution looking for a problem.

Framed as 'Day 36 of #100DaysChallenge', i.e. a practice project rather than a product for a defined user.

What stops someone copying it?
A thin, common exercise that anyone could rebuild in a weekend; there is no data, integration, or local depth.

Infrastructure
Does a real, working product exist?
A real, live, working page exists with validation and calculation, but it is a thin single-purpose front end with no backend, accounts, or docs.

- Real product25/35
The page is live and the post describes working validation, error states and age calculation, but it is a single-function page with a simplified calculation (30-day months).

Only a static page on GitHub Pages; no backend, accounts, docs, API, or status page. The post links a source repo, which is a minimal sign of practice.
