Description
Zap Code generates working HTML/CSS/JS from plain English descriptions, designed for kids ages 8-16.The core loop: kid types "make a space shooter game", AI generates the code, live preview renders it immediately. Three interaction modes - visual-only tweaks, read-only code view with annotations, and full code editing with AI autocomplete.Technical details: Next.js frontend, Node.js backend, Monaco editor simplified for younger users, sandboxed iframe for preview execution (no external API calls from generated code). Progressive complexity engine uses a skill model to decide when to surface more advanced features.Main thing that was focused on was the gap between block-based coding (Scratch, etc.) and actual programming. Block tools are great for ages 6-10 but the transition to real code is rough. This tries to smooth that curve by letting kids interact with real output first, then gradually exposing the code behind it.Limitations: AI-generated code isn't always clean or idiomatic. Content is filtered for age-appropriateness but its not perfect. Collaboration features are still basic. The complexity engine needs more data to tune well.Free tier, 3 projects. Pro at $9.99/mo.

Could you build this?
Yes It generates client-side HTML/CSS/JS via standard LLM API prompts and embeds the output into an iframe preview alongside code-view tabs.
