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 13 June 2026; the live site may have changed since.

Synapse PDF still has work before launch. Worth fixing first: missing several security headers, no robots.txt or sitemap, and no email security records.

Launched on Product Hunt on June 13, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 3 weeks before launch. The crawl picked up 4 technologies on this site, covering DNS providers, web fonts, hosting, and security. The stack includes Google Fonts, HSTS, and Netlify.

For context, it's running the same core stack as 932 other launches.
