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 5 July 2026; the live site may have changed since.

FlexTools Pro ships with the basics, with clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on July 5, 2026. The site is hosted on Vercel. We've detected 18 technologies on this site, covering javascript library, advertising, package cdn, and analytics. The stack includes cdnjs, Google Analytics, and Google Fonts.

It's on one of the most common stacks we track, shared by 2,548 launches.
