StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 18 August 2026; the live site may have changed since.

Flipnotes covers some of the launch checklist, with a thorough launch checklist and well-configured email security. What needs work: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Product Hunt on August 18, 2026. The site is hosted on Vercel, with a domain registered 8 months before launch. Our crawler found 14 technologies on this site, covering javascript library, ui library, advertising, and AI builders. The stack includes Tailwind CSS, Clicky, and Facebook Pixel.

It's also running the same core stack as 3,000 other launches.
