The problem

Most AI builders don't care about your system.

They generate UI fast, but it's not your UI.

AI builders ignore your design system

Generic components and random tokens. Every generation drifts further from your actual UI library.

Iteration breaks consistency

Ask for changes and watch your carefully chosen components get replaced with defaults.

Prototypes you can't actually ship

The code looks good until you realize it's not using your Button, Card, or any real component.

How it works

Three steps to building UI that stays true to your system.

01

We learn your design system

Connect Storybook, import design tokens, or upload component docs. Lunet maps your library: components, variants, props, and constraints.

02

Prompt and generate

Describe your UI in natural language. Lunet generates React/Next.js code using only your actual components and design tokens.

03

Iterate without drift

Refine in chat. Add features, adjust layouts, or fix details. Every change respects your design system with no random replacements.

Key features

Everything you need to move from idea to working prototype — while staying true to your design system.

Prompt → running prototype

Generate production-ready React/Next.js code from natural language. No configuration needed.

Live preview + code access

See your UI update in real-time with instant access to the underlying component code.

Chat-based iteration

Refine your prototype conversationally. Lunet maintains full project context across edits.

Version snapshots

Capture key milestones and roll back to previous states when needed. (Basic versioning included)

Private design system support

Connect to your private Storybook instances and custom token files securely.

Beta

Figma/screenshot input

Reference visual designs alongside prompts for better context. (Beta feature)

A 90-second proof.

Watch how Lunet builds, previews, and iterates — all while respecting your design system.

Why Lunet

Built for teams who care about design system integrity, not just velocity.

Design-system-correct by default

Other builders optimize for speed. We optimize for fidelity to your system. Every component, every token, every pattern matches what your team already uses.

No drift across iterations

Make a change, and only that change happens. Your earlier work stays intact. No mysterious regressions or style resets.

Production-like code from day one

Output isn't a prototype you throw away. It's real components with proper props, tokens, and structure your engineers can ship.

The difference: Generic AI builders are great for exploration. Lunet is built for teams with a design system who need AI without compromise.

Your components • Your tokens • Your patterns • Zero drift

Who it's for

Lunet is designed for teams who treat their design system as a source of truth.

Built for

  • Design system teams
  • Product designers shipping UI
  • Frontend teams needing consistent scaffolding

Not for

  • Freeform styling exploration with no constraints
  • Teams with no design system

If you're building with a component library and design tokens, Lunet will feel like a native extension of your workflow.
