I built FreeAIGen because I was frustrated with existing AI image generators that either require signups, add watermarks, or have excessive ads.

Tech stack: - Next.js App Router for the frontend - AI-SDK for image generation with Replicate backend - PostgreSQL for user data and credit management - [Include any interesting technical challenges you solved]

I'm particularly proud of how we: 1. Implemented a credit system that works for both registered and anonymous users 2. Optimized image generation for speed and quality 3. Built a clean, no-nonsense UI focused on the core task

I'd appreciate any feedback on both the product and technical implementation.
