What its author says it does

Copied from the file, not written here

Audit a product before going live — core user flows, landing copy, trust signals, SEO basics, analytics, email deliverability, and stability — producing a launch readiness report with blockers ranked by impact. Use when the user asks to "review my app before launch," "do a pre-launch audit," "check if I'm ready to launch," or is about to announce publicly.

Pre-Launch Checklist

The checklist every vibe-coded app should run before announcing to the world. Catches the gotchas that kill first impressions: broken flows, missing trust signals, confusing copy, no analytics, no way to contact you.

Context

Read product-context.md if present. If not, ask for the product URL and a one-line description before proceeding.

Process

If a live URL is available, first run the automated checks — they cover HTTPS, meta/OG tags, favicon, robots.txt, sitemap, and 404 handling in one pass:

bash scripts/check_site.sh https://yourdomain.com

Merge its 🔴/🟡 results into the report, then work through the sections below that curl can't verify (flows, emails, copy, payments). Produce a pass/fail for each item with a one-line fix where it fails.

1. Core user flow (5 minutes)

Go through the app as a brand-new user with no prior knowledge:

  • The sign-up or onboarding flow completes without errors
  • The core value action (the one thing the app does) is reachable within 2 clicks of landing
  • Error states show a human-readable message, not a stack trace or blank screen
  • Mobile layout works — key actions are tap-accessible
  • Slow 3G simulation: the page loads something meaningful in under 3 seconds
  • Email confirmation, password reset, and magic links work and deliver within 60 seconds

2. Landing page copy

Read the hero section as if you've never heard of the product:

  • The headline communicates what the product does, not what it is called
  • There is a clear primary CTA above the fold (one action, not three)
  • The subheadline addresses the pain or promise — not features
  • There is at least one piece of social proof (testimonial, user count, logo, screenshot)
  • The pricing is either shown or there is a clear path to find it
  • The page has a contact method or a way to reach the founder (email, Twitter, etc.)

3. Trust signals

  • The domain has HTTPS (no mixed-content warnings)
  • A privacy policy page exists and is linked in the footer
  • Terms of service exists if the product collects payments or user data
  • If collecting payments: the checkout flow uses a recognized provider (Stripe, Paddle, Lemon Squeezy) and shows the product name, price, and billing period clearly
  • The founder or company name is visible somewhere on the site
  • Social links, if listed, are real and active accounts

4. SEO & discoverability basics

  • The <title> tag includes the product name and a keyword phrase
  • The meta description (under 160 chars) communicates the core value proposition
  • The OG image (used when shared on X, LinkedIn, Slack) shows the product name and is not a blank box
  • The page is not blocked by robots.txt or noindex
  • A sitemap.xml exists and is accessible

5. Analytics

  • At least one analytics tool is installed and receiving events (Vercel Analytics, Plausible, PostHog, Google Analytics)
  • Signup / waitlist submission events are tracked
  • The core conversion event (the action that means a user "got it") fires correctly

6. Communication

  • Transactional emails (welcome, confirmation, password reset) send correctly and land in inbox, not spam
  • The "from" name is the product name, not [email protected] or a generated domain
  • There is at least one way to receive user feedback (email, in-app widget, Typeform, etc.)

7. Copy & content

  • Zero lorem ipsum or placeholder text remains
  • No "Coming soon" buttons that lead nowhere without a note
  • Pricing page (if present) matches the actual Stripe products/prices
  • No dead links in the footer or navigation

8. Performance & stability

  • The app has been tested in Chrome, Safari, and Firefox
  • Database connection limits won't be hit at 10 concurrent users (for Neon/Supabase free tiers: check the connection pool setting)
  • Rate limiting exists on any endpoint a bot could spam (signup, email, etc.)
  • Environment variables are set for production (not just .env.local)

Output

Produce a launch readiness report with:

## Pre-Launch Checklist Results

### ✅ Ready
- [list of passing items]

### 🔴 Blockers (fix before launch)
- [item] → [one-line fix]

### 🟡 Nice to fix (won't kill launch, fix this week)
- [item] → [one-line fix]

### Launch verdict
Ready to launch / Launch after fixing blockers / Hold for a day

Prioritize blockers by impact on first impressions and payment trust. A broken payment flow is a blocker; a missing favicon is not.

Ready to make launch content? Once this checklist passes, SoloMax turns your product URL into a launch video, hooks, and captions in minutes.
