2 things to look at
- no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
- 8 stars8 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

Google Stitch MCP Knowledge Base
Cos'è Stitch
Google Stitch (Google Labs) è un tool AI che genera UI design completi + codice da prompt testuali. Powered by Gemini 2.5 Pro. Free tier: 350 generazioni/mese.
Output supportati: HTML, CSS, React, TypeScript — non solo HTML/CSS. Richiede minima conversione per Next.js.
MCP Server: Remote MCP cloud-side (https://stitch.googleapis.com/mcp). Autenticazione via API Key.
Setup (una tantum)
- Vai su stitch.withgoogle.com → Settings → Create API Key
- Aggiungi in

Iterazione / Modifica Layout
Per modificare un design esistente:
1. Hai già generato uno screen → nota il screenId
2. Chiama generate_screen() con:
- prompt che descrive la MODIFICA: "same layout but dark background,
remove the screenshot, add trust logos bar below the hero"
- projectId del progetto esistente
3. Stitch genera un nuovo screen iterato
4. get_screen_code() → codice aggiornato
Pattern iterazione:
- "Keep the same structure but change [X] to [Y]"
- "Same layout, add [elemento] between [sezione A] and [sezione B]"
- "Make it more [minimal/bold/corporate], keep the content"
- "Adapt this for mobile, single column layout"
Prompt Engineering per Stitch
Il prompt è il fattore più importante. Struttura ottimale:
[Tipo screen] + [Stile visivo] + [Contenuto] + [Device target]
Template prompt per sezioni comuni
Hero section:
Design a modern SaaS landing page hero section. Clean minimal style with
a bold headline, subtitle, primary CTA button, and secondary link.
Dark background with blue accent. Desktop web layout.
Pricing section:
Create a pricing comparison section with 3 tiers (Starter, Pro, Enterprise).
Card layout, monthly/yearly toggle, highlighted recommended plan.
Clean light background, subtle shadows. Desktop web.
Contact form:
Design a clean contact form section with name, email, message fields
and submit button. Minimal corporate style, white background,
subtle border radius. Mobile-first layout.
Navigation/header:
Modern SaaS navigation bar with logo placeholder, nav links,
CTA button. Sticky header, light background, subtle bottom border.
Feature grid:
Feature section with 6 cards in a 3x2 grid. Each card has an icon,
title, and 2-line description. Light gray background, white cards,
rounded corners. Tech startup aesthetic.
Mappatura HTML/CSS → Tailwind
Quando leggi il codice HTML/CSS da get_screen_code:
Colori
Cerca: background-color, color, border-color, fill
Mappa a variabili CSS di shadcn quando possibile:
#fff → bg-background
#0f172a → text-foreground
#3b82f6 → bg-primary (o colore custom in @theme)
#f8fafc → bg-muted
Spacing
padding: 16px → p-4
padding: 24px → p-6
padding: 32px → p-8
margin: 8px → m-2
gap: 16px → gap-4
gap: 24px → gap-6
Tipografia
font-size: 14px → text-sm
font-size: 16px → text-base
font-size: 20px → text-xl
font-size: 24px → text-2xl
font-size: 36px → text-4xl
font-weight: 400 → font-normal
font-weight: 600 → font-semibold
font-weight: 700 → font-bold
Border-radius
4px → rounded
6px → rounded-md
8px → rounded-lg
12px → rounded-xl
16px → rounded-2xl
9999px → rounded-full
Integrazione shadcn/ui
Mappa elementi HTML Stitch a componenti shadcn:
| HTML Stitch | shadcn Component |
|---|---|
<button> primario | Button (default) |
<button> secondario | Button variant="outline" |
| Card con padding | Card, CardHeader, CardContent |
<input type="text"> | Input |
<select> | Select |
| Badge/tag | Badge |
<form> | Form (react-hook-form) |
| Tabs | Tabs, TabsList, TabsTrigger |
| Accordion | Accordion |
Budget Management (350/mese)
- Non sprecare su variazioni minori — descrivi bene al primo tentativo
- Un prompt ben costruito vale 3 tentativi vaghi
- Per variazioni colore/tipografia: modifica il TSX manualmente invece di rigenerare
- Usa
list_projectsper tenere traccia degli screen già generati e riusarli
Limitazioni da Comunicare
- React/TS output disponibile — Richiede adattamento minimo per Next.js App Router (no
'use client', imports diversi), ma molto meno lavoro di conversione rispetto a HTML/CSS puro - No design system awareness — Non conosce il tuo Tailwind theme. I colori e spacing vanno normalizzati alle tue CSS vars
- Desktop-first — I design generati sono tipicamente desktop. Documentare sempre mobile behavior
- No brand consistency automatica — Non ricorda stili precedenti. Includere sempre brand colors e font nel prompt per coerenza
- Modifica = iterazione — Non è WYSIWYG. Per modificare descrivi la modifica in un nuovo prompt
- Free tier — 350 generazioni/mese. Pianifica l'uso su progetti grandi
