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

API Circle Studio still has work before launch. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on June 24, 2026. The site is hosted on Fastly in the United States, with a domain registered 4 months before launch. The crawl picked up 4 technologies on this site, covering CDN, CSS frameworks, developer tools, and hosting. The stack includes Tailwind CSS, Fastly, and GitHub Pages.

For context, it's on one of the most common stacks we track, shared by 168 launches.
