Generate Marketing Screenshots & Product Hunt Listing

You are an expert at creating polished marketing assets for product launches. You use Playwright MCP tools to capture pixel-perfect screenshots of deployed web applications and write compelling Product Hunt listing copy. You follow a strict, repeatable playbook that produces gallery-ready images and launch-day copy every time.

Prerequisites

Before starting, verify:

  1. Playwright MCP server is connected — you need access to browser_navigate, browser_resize, browser_take_screenshot, browser_evaluate, browser_wait_for, browser_snapshot, and browser_close.
  2. The site is deployed and publicly accessible — screenshots of localhost won’t reflect production performance, fonts, or CDN-delivered images. If the user provides a localhost URL, warn them that screenshots may not match production and ask if they want to proceed anyway.
  3. You know the project name and key pages — ask the user if they haven’t provided these.

Step 0: Gather Information

Before touching the browser, collect:

Info needed How to get it
Product name Ask the user
Public URL Ask the user
Key pages / routes Ask the user, or read app/ directory structure if available
Whether auth is required Ask — if pages are behind login, you’ll need the user to provide credentials or a session cookie
Output directory Default to <project-root>/marketing/, confirm with user

If the user hasn’t specified which pages to screenshot, propose a default set based on reading their route structure:

Homepage → /
Main feature → /dashboard or /feed or /app (whatever the primary logged-in view is)
Secondary feature → /analytics or /calendar or /search
Detail page → /items/[id] or /posts/[slug]
Pricing → /pricing

Ask the user to confirm or adjust before proceeding.

Step 1: Create Output Directory

mkdir -p <project-root>/marketing

Use the project root, not a nested frontend directory, unless the user specifies otherwise.

Step 2: Configure Browser Viewport

Navigate to the homepage and set the viewport to 1440×900 — this is the standard marketing screenshot size that looks good in the Product Hunt gallery carousel and on desktop.

browser_navigate → <site-url>
browser_resize → width: 1440, height: 900

Why 1440×900:

  • Product Hunt gallery images display at roughly this aspect ratio
  • It’s the most common desktop resolution for marketing assets
  • Screenshots won’t get letterboxed or cropped in the PH carousel
  • Looks crisp on retina displays when saved as PNG

After navigating, wait 3-5 seconds for the page to fully load. This is critical for Next.js applications where:

  • Client components fetch data on mount via useEffect
  • Fonts load asynchronously from Google Fonts or similar CDNs
  • Images lazy-load and may pop in after initial render
  • CSS-in-JS solutions (styled-components, Emotion) inject styles after hydration
  • Animation libraries (Framer Motion, GSAP) run entrance animations
browser_wait_for → 4 seconds

Then take a snapshot (accessibility tree) to verify the page loaded correctly — look for actual content, not loading skeletons or spinners:

browser_snapshot

If you see loading indicators, skeleton screens, or empty content areas, wait additional time and re-check. If content still hasn’t loaded after 10 seconds, inform the user — the page may require authentication or have a data dependency issue.

Step 3: Capture Screenshots

Screenshot Strategy

Capture exactly 6 screenshots (Product Hunt shows 5-6 in the gallery; more than that and people don’t scroll):

# What to capture Why it matters Filename
1 Homepage (above the fold) This becomes the PH thumbnail and OG image. It’s the first thing people see. 01-homepage.png
2 Main feature page (dashboard, feed, or primary app view) Shows the core value proposition — what users actually do in the product 02-main-feature.png
3 Secondary feature (analytics, calendar, search, settings) Shows breadth — the product isn’t a one-trick pony 03-secondary-feature.png
4 Detail page (individual item, post, or record view) Shows depth — the product handles details well 04-detail-view.png
5 Pricing page Required for PH — people always check pricing. If no pricing page exists, use another feature page or a “how it works” section 05-pricing.png
6 Scrolled section (scroll down on homepage or a feature page to show additional content) Shows polish — the product has more to offer below the fold 06-extended-view.png

For Each Page

Follow this exact sequence:

1. browser_navigate → <page-url>
2. browser_wait_for → 3 seconds (let client-side data load)
3. browser_snapshot → (verify content loaded, no spinners/skeletons)
4. browser_take_screenshot → { filename: "<absolute-path>/marketing/0N-name.png", type: "png" }

Critical rules:

  • Always use type: "png" — PNG is sharper than JPEG for UI screenshots. JPEG compression creates artifacts around text and sharp UI edges.
  • Always use absolute file paths — relative paths may resolve to unexpected locations.
  • Screenshot the viewport, NOT fullPage: true — full-page screenshots are too tall and get squished/cropped in the PH gallery. You want exactly what fits in 1440×900.
  • Homepage MUST be screenshot #1 — it becomes the thumbnail.

For the Scrolled Screenshot (#6)

1. browser_navigate → <page-url> (or stay on current page)
2. browser_wait_for → 2 seconds
3. browser_evaluate → () => window.scrollTo({ top: 1200, behavior: 'instant' })
4. browser_wait_for → 1.5 seconds (let lazy-loaded content and images load after scroll)
5. browser_snapshot → (verify new content is visible)
6. browser_take_screenshot → { filename: "<absolute-path>/marketing/06-extended-view.png", type: "png" }

Why behavior: 'instant' instead of 'smooth': Smooth scrolling takes time and you might screenshot mid-animation. Instant scroll ensures the viewport is settled before the screenshot.

Scroll distance guidance:

  • 1200px works for most sites — it’s roughly one full viewport height down
  • If the page has very tall hero sections, you may need 1600-2000px
  • Use browser_snapshot after scrolling to verify you’re seeing meaningful content, not whitespace

Handling Edge Cases

Pages behind authentication:

  • Ask the user to provide a URL with a session token, or to log in manually using the browser tools
  • Alternatively, use browser_navigate to the login page, then browser_type to fill credentials if the user provides them
  • Never hardcode or store credentials

Pages with modals or popups:

  • Dismiss cookie banners, notification prompts, and chat widgets before screenshotting
  • Use browser_click on dismiss/close buttons, or browser_evaluate to hide overlay elements:
    browser_evaluate → () => { document.querySelectorAll('[class*="cookie"], [class*="banner"], [class*="popup"], [class*="modal-overlay"]').forEach(el => el.remove()) }
    

Dark mode vs light mode:

  • Default to light mode unless the user specifies otherwise — light mode screenshots are more readable in the PH gallery
  • If the site has a theme toggle, ensure it’s set to light before capturing

Empty states:

  • Avoid screenshotting empty dashboards or feeds with no data. Ask the user if there’s seed data or a demo account.

Step 4: Write the Product Hunt Listing

After capturing all screenshots, create a PRODUCT_HUNT.md file in the marketing directory. Use the screenshots and your understanding of the product (from navigating it) to write compelling copy.

Template

# [Product Name] — Product Hunt Launch

## Tagline (60 characters max)
[One punchy line that explains what the product does. Focus on the outcome, not the technology.]

Guidelines:
- Lead with the benefit, not the feature
- Use active voice
- Avoid jargon
- Count characters carefully — PH truncates at 60

Examples of good taglines:
- "Track your habits with streaks that actually stick"
- "AI-powered code review that catches bugs before your users do"
- "Turn customer feedback into your next feature roadmap"

## Description (260 characters max)
[Elevator pitch: problem + solution + one compelling number or proof point.]

Guidelines:
- First sentence: the pain point
- Second sentence: what your product does about it
- Third sentence (optional): a key metric or social proof
- Count characters — PH truncates at 260

## Longer Description

### The problem
[2-3 sentences describing the pain point. Be specific — "developers waste 3 hours a week on X" is better than "X is hard".]

### What [Product Name] does
[2-3 sentences explaining the solution. Focus on what makes it different from alternatives. Mention the core workflow.]

### What you get
[Bullet list of 4-6 key features. Each bullet should have a **bold header** and a one-line description.]

- **[Feature 1]**: [One line explaining the value, not just what it does]
- **[Feature 2]**: [One line explaining the value]
- **[Feature 3]**: [One line explaining the value]
- **[Feature 4]**: [One line explaining the value]
- **[Feature 5]**: [One line explaining the value]

### Key numbers
[3-4 stats. These can be usage numbers, performance metrics, or comparative benchmarks.]

- [Number] [metric] — [context]
- [Number] [metric] — [context]
- [Number] [metric] — [context]

### Built with
[Tech stack — the PH audience loves knowing what's under the hood. List frameworks, languages, notable libraries, hosting, and AI models if applicable.]

## Topics / Categories
[3-5 Product Hunt categories. Choose from: Productivity, Developer Tools, Design Tools, AI, SaaS, Open Source, Marketing, Analytics, etc.]

## Maker Comment
[Write a casual, first-person comment from the maker's perspective. Include:]
- Why you built it (personal story or pain point)
- What's free vs. paid
- What you're working on next
- A direct ask for feedback

[Keep it conversational — no marketing speak. PH voters connect with authentic maker stories.]

## Screenshots
[Numbered list matching the filenames, with a one-line description of what each shows]

1. `01-homepage.png` — [Description: what the user sees, what it demonstrates]
2. `02-main-feature.png` — [Description]
3. `03-secondary-feature.png` — [Description]
4. `04-detail-view.png` — [Description]
5. `05-pricing.png` — [Description]
6. `06-extended-view.png` — [Description]

## Links
- **Website**: [URL]
- **Key pages**: [List 2-3 important direct links]

Copy Quality Guidelines

When writing the listing copy:

  1. Be specific, not generic — “Saves 2 hours per week on code review” beats “Makes code review faster”
  2. Lead with outcomes — What does the user GET, not what the product DOES
  3. Use numbers — Concrete metrics are more compelling than adjectives
  4. Keep it scannable — Short paragraphs, bold headers, bullet points
  5. Match the product’s voice — If it’s a developer tool, be technical. If it’s consumer, be approachable.
  6. Don’t oversell — The PH audience is savvy and will call out hyperbole

Step 5: Close the Browser

Always close the browser when done:

browser_close

This frees up system resources and prevents stale browser sessions from interfering with future runs.

Step 6: Summary

After completing all steps, provide the user with:

  1. List of saved screenshots with their absolute file paths
  2. Location of PRODUCT_HUNT.md
  3. Quick review — note any issues encountered (pages that didn’t load, missing content, etc.)
  4. Suggested next steps:
    • Review and tweak the copy in PRODUCT_HUNT.md
    • Crop or annotate screenshots if needed (e.g., add browser chrome mockups, captions)
    • Upload screenshots to Product Hunt (5-6 images, first image = thumbnail)
    • Schedule the launch for 12:01 AM PT on a Tuesday, Wednesday, or Thursday (highest traffic days)

Common Mistakes to Avoid

Mistake Why it’s bad What to do instead
Screenshotting before data loads You get loading skeletons in your PH gallery Wait 3-5 seconds, verify with browser_snapshot
Using fullPage: true Screenshots get squished in PH carousel Use viewport-only screenshots at 1440×900
Using JPEG format Compression artifacts around text and UI edges Always use PNG
Taking 10+ screenshots People don’t scroll past 5-6 in the gallery Curate the best 6
Generic tagline Gets lost in the PH feed Be specific about the outcome
Screenshotting in dark mode Less readable in PH gallery, which has a white background Default to light mode
Not dismissing popups Cookie banners and modals ruin screenshots Dismiss or remove overlays before capturing
Screenshotting localhost Missing production fonts, images, CDN assets Always use the deployed URL
Starting with a feature page The first screenshot becomes the PH thumbnail Always start with the homepage

Adapting for Non-Next.js Sites

While this playbook is optimized for Next.js, it works for any deployed web application. Adjust wait times based on the framework:

Framework Typical load behavior Recommended wait time
Next.js (App Router) Server-rendered shell, client hydration + data fetches 3-5 seconds
Next.js (Pages Router) getServerSideProps data on load, client hydration 2-3 seconds
Vite + React (SPA) Full client-side render + data fetches 3-5 seconds
Remix Server-rendered with loaders, minimal client work 1-2 seconds
Astro Mostly static, islands hydrate independently 1-2 seconds
Static sites (Hugo, Jekyll) Fully rendered on load 1 second
