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 19 July 2026; the live site may have changed since.
Tansei — A simple shelf for your Mac 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 July 19, 2026. The site is hosted on Vercel. Our crawler found 6 technologies on this site, covering transactional email, DNS providers, hosting, and payments. The stack includes Amazon SES, HSTS, and Nameserver.net.au DNS.
It's also on one of the most common stacks we track, shared by 3,048 launches and more locked down than the typical Product Hunt launch.
