SammaPix

sammapix.com — a privacy-first image toolkit with 27 browser-based tools.

Stack

• Next.js 14 App Router with TypeScript
• Canvas API for image compression, resize, crop, format conversion
• WebAssembly (HuggingFace Transformers) for AI background removal
• Web Workers for off-main-thread processing
• Tailwind CSS for styling
• Zustand + Immer for state management
• NextAuth v4 for authentication
• Stripe for payments
• Drizzle ORM + Neon PostgreSQL for database

What it does

Compress, resize, convert (HEIC/WebP/AVIF/JXL), AI background removal, passport photos (140+ countries), AI rename, batch watermark, duplicate finder, EXIF/GPS removal, and more.

Privacy-first architecture

All image processing runs entirely in the browser. Images are never uploaded to any server. The AI background removal model (RMBG-1.4) downloads once (~40MB) and runs locally via ONNX Runtime Web.

Performance

• Lighthouse: 97-99
• LCP: 1.5s mobile / 0.4s desktop
• 308 pages (programmatic SEO)
• 46 blog articles with TTS

Built as a solo project by Luca Sammarco. Would love feedback from the Next.js community!

Post claims v14, the app has v15, and we are already at 16.2.3... And also, no repository?
