Product Showcase Generator

Generate a marketing website that actually teaches people what a web app does. Not just a hero and feature grid — a multi-page site with real screenshots, animated GIF walkthroughs of workflows, feature deep-dives, and progressive depth from "what is this" to "here's exactly how it works."

Especially valuable for complex apps, agentic AI tools, and anything where a static screenshot doesn't convey the value.

Depth Levels

Default: standard

Browser Tool Detection

Before starting, detect available browser tools:

1. Chrome MCP (

   mcp__claude-in-chrome__*

   ) — preferred for authenticated apps
2. Playwright MCP (

   mcp__plugin_playwright_playwright__*

   ) — for public apps
3. playwright-cli — for scripted flows

Workflow

1. Gather Input

https://app.example.com

http://localhost:5173

2. Capture Screenshots

Use

capture-screenshots

bin/

Quick capture (all key pages at once):

capture-screenshots http://localhost:5173 \
  --pages /,/dashboard,/contacts,/settings \
  --output showcase/screenshots \
  --prefix screen \
  --mobile --dark

This produces desktop (1280x720), mobile (375px), and dark mode variants for each page in one run.

For authenticated apps:

capture-screenshots https://app.example.com \
  --pages /,/dashboard,/settings \
  --auth user:password \
  --output showcase/screenshots \
  --mobile --dark

What to capture:

a. First Impression — the main page/dashboard becomes the hero image. Note the immediate value proposition.

b. Features — each major section. Use

--pages

c. "How It Works" flow — the main workflow in sequence. Run

capture-screenshots

--prefix workflow-step

d. Detail shots — zoom into specific UI elements. Use

--full-page

e. Both modes —

--dark

Post-capture optimisation:

img-process batch showcase/screenshots --action optimise --max-width 1920 -o showcase/screenshots-opt

f. Extract the Value Propositions

Don't just list features. For each one, answer: why does the user care?

• BAD: "Contact management page"
• GOOD: "See every client, their history, and what needs attention — in one view"
• BAD: "Search functionality"
• GOOD: "Find anything in seconds — semantic search understands what you mean, not just what you type"

3. Generate the Site

Quick Mode: Single Page (same as before)

One HTML file: hero + feature grid + CTA. Use for MVPs and quick marketing.

Standard Mode: Multi-Page Site

showcase/
├── index.html              # Home — hero, overview, feature highlights, CTA
├── features.html           # All features with screenshots and descriptions
├── how-it-works.html       # Step-by-step workflow walkthrough with screenshots
├── screenshots/            # All captured images
│   ├── hero.png
│   ├── feature-*.png
│   ├── workflow-step-*.png
│   └── *.gif               # Animated walkthroughs
└── styles.css              # Shared styles (or inline Tailwind CDN)

Home page: Hero with animated GIF or key screenshot, 3-4 feature highlights (not all features — just the best), "How It Works" summary (3 steps), CTA.

Features page: Every feature with a real screenshot and benefit-focused description. Group by category if there are 6+. Each feature gets enough space to actually explain what it does.

How It Works page: The primary workflow as a step-by-step visual guide. Each step has a screenshot (or animated GIF), a heading, and 2-3 sentences. This page answers "ok but what does using it actually look like?"

Thorough Mode: Comprehensive Site

showcase/
├── index.html              # Home — hero, overview, value proposition
├── features/
│   ├── index.html          # Feature overview grid
│   ├── [feature-1].html    # Deep-dive: one page per major feature
│   ├── [feature-2].html    # Each with screenshots, GIFs, use cases
│   └── [feature-n].html
├── how-it-works.html       # Full workflow walkthrough
├── use-cases/
│   ├── [use-case-1].html   # Scenario: "A day in the life of..."
│   └── [use-case-2].html   # Scenario: "When a new client calls..."
├── compare.html            # "Why [app] vs alternatives" (optional)
├── screenshots/
│   ├── hero.png
│   ├── feature-*/           # Per-feature screenshot sets
│   └── workflows/           # Animated GIFs
└── styles.css

Per-feature deep-dive pages: Each major feature gets its own page with:

• Hero screenshot of the feature in action
• "What it does" — 1-2 paragraphs explaining the value
• "How it works" — step-by-step with screenshots or GIF
• "Why it matters" — the problem this solves
• Edge cases or power-user tips
• Link to next feature (flow between pages)

Use case pages: Story-driven pages that show the app in a real scenario:

• "It's Monday morning. You open the dashboard and see..."
• Walk through a realistic workflow with screenshots at each step
• Show the outcome — what's different because the user used this app
• These are the most persuasive pages for apps that are hard to explain

Comparison page (optional): "Why [app] vs [alternatives]" — honest comparison, not marketing fluff. Feature table, key differentiators, who it's best for.

4. Animated GIF Walkthroughs

Static screenshots don't convey workflow. For key features, capture animated GIFs that show the actual interaction:

How to capture (using Playwright or Chrome MCP):

1. Navigate to the starting state
2. Start recording screenshots at ~2fps
3. Perform the workflow (click, type, navigate)
4. Stop recording
5. Combine frames into a GIF

Generating the GIF — capture sequential screenshots then combine:

# Capture each step with a sequential prefix
capture-screenshots http://localhost:5173/clients \
  --prefix workflow-01 --output .jez/screenshots
# ... navigate to next state ...
capture-screenshots http://localhost:5173/clients/new \
  --prefix workflow-02 --output .jez/screenshots

# Combine frames into GIF (Python one-liner using Pillow)
python3 -c "
from PIL import Image; import glob
frames = [Image.open(f) for f in sorted(glob.glob('.jez/screenshots/workflow-*.png'))]
frames[0].save('showcase/screenshots/workflows/create-client.gif',
    save_all=True, append_images=frames[1:], duration=500, loop=0)
"

What to animate:

• The primary "create something" flow (2-4 seconds)
• A search/filter interaction (show results appearing)
• A drag-and-drop or reorder operation
• Dark mode toggle (satisfying visual)
• Any "magic moment" where the app does something impressive (AI classification, instant search, real-time update)

GIF guidelines:

• Max 10 seconds / 20 frames — shorter is better
• Capture at 1280x720, display at 640x360 (half size for file size)
• Add a brief pause (3 frames) on the final state so viewers see the result
• Loop continuously — no "click to play"
• If the GIF would be >5MB, use fewer frames or crop to the relevant area

Display in HTML:

<div class="browser-frame">
  <div class="browser-frame-bar">
    <span class="browser-frame-dot"></span>
    <span class="browser-frame-dot"></span>
    <span class="browser-frame-dot"></span>
  </div>
  <img src="screenshots/workflows/create-client.gif"
       alt="Creating a new client in 3 clicks"
       loading="lazy" width="640" height="360">
</div>

5. Explaining Agentic / AI Apps

Agentic apps are especially hard to market because the value is invisible — the AI does work the user never sees. Standard screenshots show a chat interface. That's not compelling.

Patterns that work for agentic apps:

Copy tips for agentic apps:

• Lead with the outcome, not the technology ("Know every client's history" not "AI-powered CRM")
• Show volume ("Processed 1,200 emails" is more impressive than "Processes your emails")
• Use time comparisons ("What took 2 hours now takes 30 seconds")
• Avoid jargon ("Finds connections in your data" not "Semantic vector search with RAG")

4. Screenshot Presentation

Screenshots are shown in browser-frame mockups using CSS:

.browser-frame {
  border-radius: 8px;
  box-shadow: 0 25px 50px -12px rgba(0,0,0,0.25);
  overflow: hidden;
  border: 1px solid rgba(0,0,0,0.1);
}
.browser-frame-bar {
  background: #f1f5f9;
  padding: 8px 12px;
  display: flex;
  gap: 6px;
}
.browser-frame-dot {
  width: 10px;
  height: 10px;
  border-radius: 50%;
  background: #e2e8f0;
}

This gives screenshots a polished "app in a browser" look without needing to edit the images.

6. Site Navigation

Multi-page sites need consistent navigation:

<nav>
  <a href="/">Home</a>
  <a href="/features/">Features</a>
  <a href="/how-it-works.html">How It Works</a>
  <a href="/use-cases/">Use Cases</a>  <!-- thorough only -->
  <a href="#pricing">Pricing</a>
  <button>Get Started</button>
</nav>

• Sticky nav on all pages
• Current page highlighted
• Mobile hamburger menu
• CTA button always visible in nav

7. Output

After generating, tell the user:

• Preview:

  python3 -m http.server -d showcase

  then open

  http://localhost:8000

• Deploy: drag the

  showcase/

  folder to Cloudflare Pages, Netlify, or any static host
• List any placeholder content that needs replacing
• Note which GIFs were generated and their file sizes

Design Patterns

Colour: If the app has a clear brand colour, extract it and use it as the primary. Otherwise default to a neutral palette (slate/blue).

Typography: System font stack (no external requests). Same approach as

landing-page

Responsive: Mobile-first, screenshots scale down gracefully. On mobile, screenshots stack vertically instead of grid.

Dark mode: Three-state toggle (light/dark/system) with CSS custom properties.

Performance: Lazy-load screenshot images. Tailwind CDN for styling. No build step.

Making It Look Premium

Screenshot Enhancement

• Clean data: Before screenshotting, make sure the app has realistic data — not "Test Client" and "asdf@example.com"
• Consistent window size: All screenshots at the same viewport width (1280x720)
• No browser chrome in screenshots: Use the CSS browser-frame mockup instead of capturing the actual Chrome toolbar
• Highlight the action: If a screenshot shows a feature, have that feature active/open (modal open, filter applied, item selected)

Visual Storytelling

• Lead with the dashboard: The hero screenshot should show the app populated with data, looking alive and useful
• Show the app doing work: Screenshots of results are better than screenshots of empty forms
• Progressive reveal: Hero shows the big picture, how-it-works shows the flow, features show the details
• End with the payoff: The final section before the CTA should show the result — a report generated, a task completed, a client managed

Mix Screenshots with Mockups

Real screenshots show the product is real. Mockups show the product is polished. Use both:

• Hero: Real screenshot in a browser-frame mockup — proves the app exists and looks good
• How It Works: Can use simplified mockup illustrations (CSS shapes, icons, arrows) for the flow steps, with real screenshots for the detail
• Feature grid: Real screenshots — users want to see the actual UI
• Mobile showcase: CSS device frame mockup (phone outline) around a mobile screenshot
• Dashboard/overview: Real screenshot — this is the money shot

Phone mockup frame (CSS):

.phone-frame {
  border: 8px solid #1f2937;
  border-radius: 32px;
  overflow: hidden;
  max-width: 280px;
  box-shadow: 0 25px 50px -12px rgba(0,0,0,0.3);
}
.phone-frame-notch {
  background: #1f2937;
  height: 24px;
  border-radius: 0 0 16px 16px;
  width: 120px;
  margin: 0 auto;
}

Animation (CSS-only, no JS required)

/* Fade in sections as user scrolls (intersection observer via CSS) */
@keyframes fadeInUp {
  from { opacity: 0; transform: translateY(20px); }
  to { opacity: 1; transform: translateY(0); }
}
.section { animation: fadeInUp 0.6s ease-out both; }

/* Subtle float on hero screenshot */
@keyframes float {
  0%, 100% { transform: translateY(0); }
  50% { transform: translateY(-8px); }
}
.hero-screenshot { animation: float 6s ease-in-out infinite; }

Gradient Accents

Extract the app's primary colour and use it for subtle gradient backgrounds on sections:

.hero { background: linear-gradient(135deg, var(--primary) 0%, transparent 60%); }
.cta-banner { background: linear-gradient(135deg, var(--primary), var(--primary-dark)); color: white; }

Deployment

The showcase site needs to be hosted somewhere real — not just opened from a file. Choose based on what's available:

Option 1: Cloudflare Workers with Static Assets (recommended)

If the app being showcased is already on Cloudflare, deploy the showcase as a Worker too:

# In the showcase/ directory, create a minimal wrangler.jsonc:
{
  "name": "myapp-showcase",
  "main": "src/index.ts",  // or use static-only pattern
  "compatibility_date": "2026-03-01",
  "assets": { "directory": "./" }
}

npx wrangler deploy

Or attach a custom domain:

showcase.myapp.com

myapp.com

app.myapp.com

Option 2: Cloudflare Pages (drag-and-drop)

Dashboard → Pages → Create → Upload assets → drag the

showcase/

.pages.dev

Option 3: Static host (Netlify, Vercel, GitHub Pages)

Any static host works — it's just HTML + CSS + images. No server-side code.

Custom Domain

For a professional showcase, always use a custom domain:

• myapp.com

  — showcase is the main site, app is at

  app.myapp.com

• www.myapp.com

  → showcase,

  app.myapp.com

  → the actual app

Contact / Enquiry Forms

Every showcase needs a way for interested people to get in touch. Don't just put "email us" — add a real form.

Pattern 1: Formspree / Formsubmit (no backend needed)

<form action="https://formspree.io/f/YOUR_FORM_ID" method="POST">
  <input type="text" name="name" placeholder="Your name" required>
  <input type="email" name="email" placeholder="Your email" required>
  <textarea name="message" placeholder="Tell us about your needs"></textarea>
  <button type="submit">Get in Touch</button>
</form>

Free tier handles most showcase volumes. Submissions go to your email.

Pattern 2: Cloudflare Worker endpoint

If the showcase is on Workers, add a

/api/enquiry

app.post('/api/enquiry', async (c) => {
  const { name, email, message } = await c.req.json();
  // Send via SMTP2Go, Resend, or store in D1
  await sendEmail({ to: 'hello@company.com', subject: `Enquiry from ${name}`, body: message });
  return c.json({ success: true });
});

Pattern 3: Turnstile + email (spam protection)

Add Cloudflare Turnstile to prevent bot submissions:

<div class="cf-turnstile" data-sitekey="YOUR_SITE_KEY"></div>

Verify the token server-side before processing the submission.

What the form should capture

After submission: redirect to a thank-you page or show an inline confirmation. Don't just reset the form silently.

Additional Pages Worth Generating

/app-docs

SEO Basics

Every showcase page should have:

<title>[App Name] — [Tagline]</title>
<meta name="description" content="[One sentence value proposition]">
<meta property="og:title" content="[App Name]">
<meta property="og:description" content="[Value proposition]">
<meta property="og:image" content="screenshots/hero.png">
<link rel="canonical" href="https://myapp.com/">

For multi-page: each page gets its own title and description. Don't use the same meta across all pages.

Use the

Quality Rules

1. Only screenshot real features — don't fabricate capabilities the app doesn't have
2. Choose the best screenshots — not every page is showcase-worthy. Pick the ones that tell the product story
3. Write benefit-focused copy — "See all your contacts in one place" not "Contact list page"
4. Browser frames on screenshots — always wrap in the CSS mockup for professional appearance
5. Consistent screenshot size — all at 1280x720 for the captures, CSS handles display sizing
6. No fake testimonials — leave the section out if none provided
7. No invented statistics — leave stats blocks empty if no real data
8. Forms must submit somewhere — never ship a form that goes nowhere
9. Every page needs navigation — consistent nav, mobile hamburger, CTA always visible
10. Deploy to a real URL — don't leave it as local files. A showcase needs to be shareable.
