It is a library call with a user interface. Static QR codes cost nothing, and dynamic redirects with scan counts take an afternoon.

the prompt

Curated prompt
Build me a QR code generator like QR Tiger, self-hosted. Requirements:

- A single page: enter a URL or text, live-preview the QR code, customize
  foreground/background color, corner style, and an optional center logo upload.
  Use the qr-code-styling library. Export as PNG or SVG.
- Dynamic QR codes: /r/:slug 302-redirects to a target URL stored in SQLite,
  so the destination can be edited later without reprinting the code. CRUD for
  these behind basic-auth (/admin, credentials from .env).
- Scan tracking for dynamic codes: log timestamp + user-agent + referer per hit,
  show per-code totals and a 30-day count in the admin list.
- Clean minimal UI, mobile-friendly, no accounts, no third-party calls.
- Node, one process, SQLite file storage, deploy notes for a VPS.

Build Pack

Build a QR Tiger replacement: the plan

What to build, what to skip on purpose, and how to tell it works. Use any agent or prompt you like — the acceptance tests decide whether it worked.

In scope

  • Interactive QR studio page: live preview with custom foreground/background colors, dot/corner styles and optional center logo
  • Vector SVG and high-DPI PNG export generated client-side with qr-code-styling
  • Dynamic QR codes at /r/:slug that 302-redirect to a destination URL stored in SQLite so print materials never go stale
  • Basic-auth /admin page to create dynamic codes, edit their target URL later, and view total plus 30-day scan counts
  • Scan log recording timestamp, user-agent and referer on every /r/:slug hit

Non-goals

  • Multi-tenant accounts, billing tiers or public dynamic-QR hosting for strangers
  • Bulk CSV batch generation of hundreds of distinct print codes at once
  • Landing-page micro-sites for vCards, Wi-Fi or restaurant menus
  • GPS-prompted precise location tracking of scanners

Recommended stack

Runtime
Node 22 + Fastify (single process)Handles both the static QR designer UI and the /r/:slug redirect endpoint
QR rendering
qr-code-stylingSupports custom eye shapes, palettes, embedded logos and clean SVG/PNG export
Storage
SQLite (better-sqlite3)Stores dynamic redirect mappings and scan logs in one local file
Reverse proxy
CaddyAutomatic HTTPS on the domain encoded inside your printed QR codes

Data model

  • codessluglabeldestination_urlstyle_jsoncreated_atupdated_atdestination_url can be updated anytime without changing the printed /r/:slug URL
  • scansidslugtsuser_agentrefererIndexed on (slug, ts) for total and 30-day scan counts

Steps

  1. Static QR designerBuild the browser UI around qr-code-styling: URL/text input, color pickers, corner style selector, logo upload and PNG/SVG download.
  2. SQLite schemaCreate the codes and scans tables in SQLite with an index on scans(slug, ts).
  3. Dynamic redirect routeImplement GET /r/:slug: look up destination_url in codes, insert a scan row, and return a 302 redirect (or 404 if missing).
  4. Admin CRUD and statsProtect /admin with Basic Auth from .env; allow creating a dynamic slug, editing its destination_url, and viewing scan totals.
  5. Deploy behind HTTPSDeploy on your domain behind Caddy and document that printed dynamic codes depend on keeping that domain active.

Acceptance tests

  • Customize colors and a center logo, Export SVG, and scan with a phone cameraThe exported QR code scans reliably on the first try
  • Create dynamic code /r/menu pointing to URL A, then update it in /admin to URL BScanning the original unchanged QR code now redirects to URL B
  • Scan /r/menu three times/admin shows 3 total scans and 3 scans in the last 30 days
  • Open /admin without credentialsReturns 401 Unauthorized

Only you can do this

  • Choose a short domain you plan to keep renewing for years before printing physical QR codes
  • Set ADMIN_USER and ADMIN_PASSWORD in .env
  • Test printed contrast with a real phone camera before sending artwork to a print shop

What drives the cost

Static QR generation is pure client-side code and costs $0. Hosting dynamic redirects (/r/:slug) costs $0 on an existing server or Cloudflare Worker, or $4–$5/month on a basic VPS plus your domain renewal.

The honest tradeoff

why people still pay

Paying customers buy hosted dynamic codes on someone else's domain, scan analytics, and bulk generation, which few individuals need.

questions

Can AI replace QR Tiger?

Likely for the core workflow. This is an editorial catalog judgment, not a verified build; validate any result against your own acceptance criteria.

How much does QR Tiger cost?

QR Tiger is listed at about $15/month (Regular, checked 2026-10-04), or $180 per year. This is a pricing reference, not evidence of a completed replacement or realized savings.

What do I lose by replacing QR Tiger?

Honestly: hosted dynamic-QR redirects on their domain; their scan-analytics dashboard; bulk generation UI. If any of those are load-bearing for you, keep paying.

Is there an open-source alternative to QR Tiger?

Yes — qr-code-styling (the styling library that does the heavy lifting). Using prior art is also a valid exit; the prompt is for when you want it exactly your way.
