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 28 April 2026; the live site may have changed since.

FlipFlow is largely in shape, with complete legal pages and clean crawl signals. Visible gaps: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on April 28, 2026. The site is hosted on Vercel. The crawl picked up 14 technologies on this site, covering auth, analytics, CSS frameworks, and DNS providers. The stack includes Auth.js, Google Sign-In, and Next.js.

For context, it's on one of the most common stacks we track, shared by 10,662 launches.

Readiness Breakdown How?

Custom title and meta description
Canonical URL declared
Responsive viewport meta tag
Semantic HTML (nav, main, article)
Page title is 67 characters (advisory) Google only shows about 60 characters of the title in search results; aim for 50–60 to keep the whole thing visible.
Meta description is 212 characters (advisory) Google only shows about 155–160 characters of the description in desktop search results (less on mobile); anything past that won't appear.
!
Localhost / private-network references (-10 points) Site references http://localhost or private-network URLs (e.g. 192.168.x.x) in asset tags. These will fail to load for public visitors.
- Open Graph tags (title, image, description)
- Twitter card meta tags
- Favicon present
