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 27 June 2026; the live site may have changed since.
Capsul is partway there, with complete legal pages and a thorough launch checklist. Visible gaps: missing several security headers, no robots.txt or sitemap, and incomplete email security.
Launched on Product Hunt on June 27, 2026. The site is hosted on WholeSale Internet in the United States, with a domain registered 5 months before launch. The crawl picked up 9 technologies on this site, covering ui library, baas, CSS frameworks, and frameworks. The stack includes Next.js, React, and Tailwind CSS.
For context, it's on one of the most common stacks we track, shared by 3,045 launches.
