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

FlowToolkit has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers and no email security records.

Launched on Product Hunt on June 6, 2026. The site is hosted on Hostinger International Limited in Lithuania. Our crawler found 9 technologies on this site, covering analytics, consent tooling, CSS frameworks, and frameworks. The stack includes Google, Next.js, and React.

Notably, it's running the same core stack as 2,284 other launches.
