🚀 Startup Launch Readiness Checker A free CLI tool that audits your startup's website before launch day — so you don't go live with broken meta tags, missing sitemaps, or slow load times. Run one command. Get a complete launch readiness score in seconds.
Why This Exists Most startup founders focus on the product and forget the launch infrastructure. Then they launch on Product Hunt, get 500 visitors… and lose half of them because:
No Open Graph tags → links look broken on social media No meta description → Google shows nothing in search results No sitemap.xml → search engines can't index the site Slow load time → users bounce before the page loads
This tool checks all of it automatically.
After fixing these issues, get your startup in front of real early adopters. List it on StartupLaunchDay.com — a curated directory where founders, investors, and early adopters discover new products.
