Building a Client-Side QR Code Generator: Privacy-First with Blazor WebAssembly

Source: Dev.to

Most QR code generators send your data to servers. I built PrismioQR – a free, privacy‑first QR code generator that creates everything in your browser using Blazor WebAssembly.

What’s Covered

• Client‑side QR code generation (zero server processing)
• Privacy‑first architecture decisions
• Blazor WebAssembly implementation
• 15+ QR code types and customization features
• Why “free” doesn’t have to mean “tracked”

Key Features

• ✅ No signup, no ads, no tracking
• ✅ Multiple export formats (PNG, SVG, PDF, JPG)
• ✅ WCAG AAA accessible

Note: Currently in maintenance mode (upgrading with new features), but the basic generator is available.
