Prototyping
AI-powered rapid prototyping
Describe what you want to build and your AI agent creates a working HTML prototype in seconds. Iterate on the design, test interactions, and hand off to production.
Free for individuals. Works with your existing Claude Code or Codex subscription or API key.
The Problem
Prototyping takes too long to validate ideas
Getting from idea to something people can interact with requires either design tool expertise or development time -- both are expensive.
- Figma prototypes look right but don't behave like real software
- Building a real prototype requires a developer -- blocking the validation loop
- Low-fidelity wireframes don't communicate intent clearly enough
- Prototype code is throwaway that nobody wants to write
How It Works
From idea to interactive prototype in minutes
Describe what to build
Tell your agent what the prototype should do -- 'build a kanban board with drag-and-drop, a dark mode toggle, and a sidebar.' It generates working HTML in seconds.
Iterate in real time
View the rendered prototype and refine it conversationally. Every change renders live, so you can test interactions and adjust the design instantly.
Evolve into production
When the prototype is validated, the same agent converts it into production components using your framework of choice.
The Difference
Validate ideas before building them
Without Nimbalyst
- ✕ Wait days for a developer to build a prototype
- ✕ Figma clickthrough doesn't test real interactions
- ✕ Prototype code is thrown away and rebuilt for production
- ✕ Ideas die in meetings because nobody can see them
With Nimbalyst
- ✓ Working prototype in minutes from a text description
- ✓ Real HTML with working interactions, not static mockups
- ✓ Prototype evolves into production code seamlessly
- ✓ Ideas get tested immediately, not discussed indefinitely
