Overview

A free all-in-one utility portal serving 179 tools across 15 categories as individual pages — calculators (net salary, taxes, unit conversion), utilities (character count, QR generator, image editing) and mini games & quizzes (reaction speed, typing). Live at calqu.kr.

Highlights

  • Single catalog (SoT) — every tool lives in one calculators.js registry; cards, navigation, sitemap and OG images are generated from it
  • Generator pipeline — card grids, programmatic pages, guides, OG images, breadcrumbs and the sitemap are all script-generated (no repetitive manual edits)
  • Policy constants isolated — year-dependent figures (tax rates, minimum wage) live only in rates-2026.js, so one yearly update completes maintenance
  • SEO & PWA — unique URL/meta/JSON-LD per tool, KO/EN i18n, dark mode, offline support

Stack

Vanilla HTML/CSS/JavaScript (no framework, no build tool) deployed statically on Firebase Hosting. All computation completes client-side — no server, no database.
