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

Tandem has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and no email security records.

Launched on Product Hunt on July 7, 2026. The site is hosted on Vercel, with a domain registered 4 months before launch. Our crawler found 10 technologies on this site, covering analytics, DNS providers, transactional email, and frameworks. The stack includes Next.js, React, and Google Search Console.

It's also running the same core stack as 2,030 other launches.
