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 1 August 2026; the live site may have changed since.
Tempo Kit scores highly overall, with complete legal pages, a thorough launch checklist, and well-configured email security. Main gaps: no Content-Security-Policy.
Launched on Product Hunt on August 1, 2026. The site is hosted on Vercel, with a domain registered 4 weeks before launch. The crawl picked up 12 technologies on this site, covering DNS providers, business email, analytics, and CSS frameworks. The stack includes Next.js, React, and Tailwind CSS.
For context, it's one of only 13 launches we've crawled running Postal and more locked down than the typical Product Hunt launch.
