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 23 April 2026; the live site may have changed since.
Speechmatics On-Device is largely in shape, with complete legal pages, a thorough launch checklist, and well-configured email security. Main gaps: missing several security headers.
Launched on Product Hunt on April 23, 2026. The site is hosted on Vercel, with a domain registered in 2006. The crawl picked up 29 technologies on this site, covering advertising, ai api, analytics, and business email. The stack includes Contentful, Cookiebot, and Next.js.
For context, it's one of only 42 launches we've crawled running Contentful.
