Overview
Kalpkodu is a gift-and-story SaaS inspired by a manual "QR poster + personal website" product I saw being sold through Instagram DMs and Canva templates. It turns that one-at-a-time, custom-design-per-order workflow into a self-serve platform: pick a theme, fill in your story, upload photos, and get a personal site plus a printable QR code that opens it — no app install, no login required for the recipient.
Key features
- 5 distinct themes — Stars, Love Letter, Cinema, Song, and Newspaper Headline, each with its own color palette, icon, and tone rather than a single reskinned template.
- Guided 5-step wizard — theme → content → photos → live preview → order confirmation, so the whole site is ready in minutes.
- Server-generated QR codes — every published site gets a downloadable PNG QR code generated on the server, no third-party QR service involved.
- Owner preview gate — the creator can view and share their site before it's live; everyone else sees a "coming soon" placeholder until the order is approved.
- Manual order approval — orders land as "pending"; an admin panel lets the operator approve or cancel them, which publishes the site and emails the buyer automatically.

Architecture notes
Each theme is a small config object (colors, icon, tagline) consumed by one shared story-site renderer, so adding a new theme is a data change, not a new page. QR codes are generated on-demand server-side from the site's public URL using the qrcode package — no external QR API dependency, no expiry.
Deployed on Vercel with a Neon Postgres database provisioned through the Vercel Marketplace integration.
