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

Sendzai looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers and incomplete email security.

Launched on Product Hunt on July 15, 2026. The site is hosted on Netlify and served through Cloudflare, with a domain registered 12 weeks before launch. We've detected 15 technologies on this site, covering javascript library, CDN, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.

It's on one of the most common stacks we track, shared by 341 launches.
