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 June 2026; the live site may have changed since.
FocusStack is largely in shape, with complete legal pages, a thorough launch checklist, and well-configured email security. Worth fixing first: missing several security headers and tracking cookies set before any opt-in.
Launched on Product Hunt on June 28, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 1 week before launch. The crawl picked up 9 technologies on this site, covering analytics, CDN, cloud, and developer tools. The stack includes Amazon SES, Amazon Web Services, and AWS CloudFront.
For context, it's running the same core stack as 289 other launches.
