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 20 May 2026; the live site may have changed since.

SetFlow scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Main gaps: incomplete email security.

Launched on Product Hunt on May 20, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 8 weeks before launch. We've detected 22 technologies on this site, covering ai api, analytics, transactional email, and security. The stack includes Auth.js, Next.js, and React.

It's on one of the most common stacks we track, shared by 10,677 launches and more locked down than the typical Product Hunt launch.
