# How to Vibe Code Your Own QR TIGER (and Stop Paying for It) > QR Code Generator & Management Platform - Site: https://qrtiger.com - Category: Marketing SaaS - Verdict: **Solid side project** (68/100 vibecodeable) - Estimated effort: 2-3 weeks part-time ## Verdict You can build a personal QR code management SaaS clone for yourself, but routing latency and asynchronous telemetry logging require careful edge architecture. Building a functional QR generator and dynamic short-link router is an achievable weekend project, but making it production-grade with reliable global edge redirection, concurrent analytics tracking, and programmatic custom logo rendering demands solid systems engineering. If you just want to manage your own dynamic QR codes, paying ~$7/mo is far cheaper than the hours you will spend debugging Redis queues and Cloudflare Worker KV edge state consistency. ### What you can't replicate - The millions of existing physical QR codes already printed on real-world product packaging pointing to production short domains - Enterprise compliance frameworks and trusted global brand recognition ## What it does Comprehensive QR code management platform enabling businesses and creators to generate, track, and manage dynamic and static QR codes with real-time analytics. ### Core features - Dynamic QR code URL shortener redirection engine (/r/{code}) - Real-time telemetry logging (IP, geolocation, user-agent, timestamp) - Vector and raster custom QR code renderer with frames and logo embedding - Dynamic landing page content updates without reprint - Analytics dashboards with scan charts and device breakdown - Bulk generation via CSV/Excel upload - Scan expiry triggers and password-protected codes ## The business ### Pricing - Free: $0 - Regular: ~$7/mo - Advanced: ~$16/mo - Enterprise: ~$89+/mo Founded 2018. Team size: ~48. ## The hard parts - Ultra-low latency global edge redirection routing so physical packaging never breaks - Asynchronous high-volume analytics logging without blocking HTTP redirect pipelines - Complex programmatic vector (SVG/PNG) graphic generation maintaining error-correction matrices with logos - Custom domain CNAME verification and SSL certificate management at scale ## How to vibe code QR TIGER ### Prerequisites - Node.js (free): Required for running the Next.js full-stack development environment. - GitHub (free): Repository hosting and continuous deployment integration. - Cloudflare account (free): Required for deploying edge-routed short link redirection workers and serverless database storage. ### Recommended AI tools - Claude Code: Best-in-class agentic coding tool for scaffolding full-stack routing logic, database schemas, and SVG generation scripts. - Cursor: Excellent for iterative frontend UI work on dashboards and analytics charts. ### Stack - Frontend: Next.js with Tailwind CSS and shadcn/ui - Backend: Next.js App Router API endpoints / Cloudflare Workers - Database: Turso (SQLite at the edge) - Auth: better-auth - Payments: None (personal use clone) - Other: qrcode npm library for matrix generation, PostHog for product analytics ### Hosting - Cloudflare (Hosting short-link edge redirect workers and static frontend assets): $0-5/mo - Turso (Serverless edge database for storing dynamic QR definitions and scan telemetry logs): $0/mo ### Build guide 1. **Project Scaffolding and Database Schema** — Initialize the Next.js project with Tailwind CSS, shadcn/ui, and set up the Turso SQLite database schema for users, dynamic QR codes, and scan logs. ``` Scaffold a new Next.js project using the App Router, TypeScript, and Tailwind CSS. Integrate shadcn/ui for component styling. Set up a Turso SQLite database connection using Drizzle ORM or native libSQL. Create three core tables: `users` (id, email, password_hash, created_at), `qr_codes` (id, user_id, title, short_code, target_url, qr_config_json, scan_count, expires_at, is_active, created_at), and `scan_logs` (id, qr_id, ip_address, user_agent, country, device_type, timestamp). Ensure proper foreign key constraints and indexes on `qr_codes.short_code` for ultra-fast lookups. Write a comprehensive migration script and verify local connection setup. ``` 2. **Authentication System with better-auth** — Implement secure authentication for managing personal QR code campaigns. ``` Integrate `better-auth` into the Next.js application using Turso as the backing data store. Set up email/password authentication with secure session cookies. Create clean sign-in and sign-up pages using Tailwind CSS and shadcn/ui components. Add protected route middleware to restrict dashboard access to authenticated users only. Verify that user registration, login, and session persistence function correctly across page reloads. ``` 3. **QR Code Generation and Customization Engine** — Build an interactive UI and backend engine to generate customized QR codes with logos and frames. ``` Build a dashboard page with an interactive QR code customizer component. Use the `qrcode` npm library combined with custom canvas/SVG manipulation to allow users to configure: foreground color, background color, dot style, eye frame style, error correction level (L, M, Q, H), and an embedded center logo image upload. Implement preview rendering in real-time as settings change. Provide export buttons for high-resolution PNG, SVG, and JPEG file formats. ``` 4. **Dynamic Short-Link Redirection Engine** — Implement the high-performance redirection route that intercepts scans, logs telemetry asynchronously, and redirects users. ``` Create a dedicated edge-compatible route handler at `/r/[shortCode]` in Next.js or a Cloudflare Worker. When a short code is requested: (1) look up the `qr_codes` record by `short_code`, (2) check if the code is active and has not passed its expiration date or scan limit, (3) extract telemetry headers including IP address, User-Agent, and geolocation headers (CF-IPCountry or geo headers), (4) asynchronously log a new entry in `scan_logs` and increment the `scan_count` on the `qr_codes` record without blocking the response, and (5) perform a fast HTTP 302 redirect to the target URL. Handle edge cases like invalid or expired codes with a clean 404 error page. ``` 5. **Analytics Dashboard and Telemetry Visualizations** — Build analytical reporting screens showing scan counts over time, device distributions, and geographic locations. ``` Build a detailed analytics view for individual dynamic QR codes within the user dashboard. Query the `scan_logs` table to aggregate data by date (time series graph using Recharts or Tailwind charts), device type (mobile, desktop, tablet), browser, and geographic country breakdown. Add summary metric cards for total scans, unique visitors, and recent scan timestamps. Ensure queries are optimized with proper database indexes for snappy page loads. ``` 6. **Management Dashboard, Bulk Actions, and Polish** — Add QR code management tools, editing capabilities for target URLs, and search/filtering features. ``` Build the main user dashboard listing all created QR codes with status toggles (active/paused), edit modals to change the target URL instantly without reprinting, delete actions, and search filtering. Add a bulk QR creation view allowing users to input a CSV list of target URLs to generate multiple dynamic codes at once. Perform end-to-end testing of the complete user journey: create dynamic code -> scan short link -> verify redirection -> inspect telemetry in analytics dashboard. ``` ### Cost vs paying **Starting costs (one-time):** - Custom domain (optional for short links): $12/yr - AI coding assistant (Claude Pro / Cursor): $20 - Total: ~$32 one-time **Ongoing costs (monthly):** - Cloudflare Workers / Turso edge hosting: $0-5/mo - Total: ~$0-5/mo - Paying for the SaaS instead: $7/mo - $16/mo - Build time: 15-25 hours - AI tool credits: $20 - Break-even: 4 months ## Sources - [QR TIGER Official Website](https://www.qrcode-tiger.com) - [GetLatka - QR Tiger Revenue, Valuation & Team Size Data](https://getlatka.com) - [RecordOwl - QRTIGER PTE.
