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

Attendance Calculator Online - Check 75% has the basics covered well, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on June 17, 2026. The site is hosted on Google LLC in the United States, with a domain registered 3 weeks before launch. Our crawler found 8 technologies on this site, covering advertising, analytics, CMS, and web fonts. The stack includes Blogger, jQuery, and cdnjs.

Notably, it's one of only 39 launches we've crawled running Blogger.
