Own this Launch?

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 10 August 2026; the live site may have changed since.

Synthii is missing several launch fundamentals. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on August 10, 2026. The site is served through Cloudflare, with a domain registered 4 months before launch. Our crawler found 6 technologies on this site, covering CDN, CSS frameworks, developer tools, and DNS providers. The stack includes Tailwind CSS, Cloudflare, and Cloudflare DNS.

It's also running the same core stack as 6,830 other launches.
