Screenshot of SwanShare

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

SwanShare looks production-ready overall, with complete legal pages, a thorough launch checklist, and well-configured email security. Visible gaps: missing several security headers.

Launched on Product Hunt on June 27, 2026. The site is hosted on Cloudflare in the United States. We've detected 13 technologies on this site, covering CDN, javascript library, cloud, and CSS frameworks. The stack includes Tailwind CSS, Amazon Web Services, and AWS CloudFront.

It's on one of the most common stacks we track, shared by 210 launches.
