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 30 April 2026; the live site may have changed since.
Sync-in has the basics covered well, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and incomplete email security.
Launched on Product Hunt on April 30, 2026. The site is hosted on Online SAS in France, with a domain registered in 2012. Our crawler found 5 technologies on this site, covering DNS providers, business email, meta-frameworks, and seo. The stack includes Docusaurus, Google Search Console, and nginx.
It's also one of just 25 launches we've crawled on this exact stack.
