Hey Product Hunt! 👋 I'm Ernesto. I built PikaIA - an open-source app generator that runs in your browser. What it does: - Write specs in plain English (Interface, Behavior, Style) - Click "Render App" → get working HTML/CSS/JS - Extract specs from existing HTML (reverse engineering) - Refine specs with natural language feedback - Switch between 10+ AI models - Preview on desktop/tablet/mobile - Export standalone HTML files What makes it different: - Single HTML file - download and run, no dependencies - BYOK - bring your own OpenRouter key, no subscription - MIT licensed - fork it, modify it, self-host it - Privacy-first - all data in your browser's localStorage - Model flexibility - free models to premium (DeepSeek, GPT-5, Claude, Gemini) Why I built it: I guess I wanted a prototyping tool that I could tweak. Something transparent - where I could see the code, control the costs, and not be locked into a walled garden. Also because I think SaaS is over, oops! Something else must come!
