What it doesLink to heading

Aunty Koi is a booking SaaS for door-to-door rides from Oahu’s North Shore to Daniel K. Inouye International Airport (HNL). Customers pick a time, pay, and get a confirmed pickup. The owner manages schedule, pricing, vehicles, and bookings from /admin. One-person operation. Real Stripe money. Runs on Cloudflare’s free tier.

  • Frontend: Vite + React 18 + TypeScript + Tailwind v4
  • Backend: Hono — runs as a local Node process for development and as Cloudflare Pages Functions in production from the same codebase
  • Database: Supabase Postgres, with concurrency handled at the database layer so overlapping bookings can’t double-book a slot
  • Payments: Stripe Checkout + refunds
  • Email: Resend for transactional mail
  • Tests: Playwright + Vitest
  • Hosting: Cloudflare Pages, end to end

Why this stackLink to heading

I wanted a small, React-first build to compare against the SvelteKit work I’d been doing. Hono I picked specifically because it runs on every JS runtime — same code, swap the adapter for the target. The “one app, two adapters” idea is the shape I’d keep.
