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 24 June 2026; the live site may have changed since.
onsubmit.dev scores well across the board, with complete legal pages, a thorough launch checklist, and fast page loads. Main gaps: missing Referrer-Policy and Permissions-Policy, tracking cookies set before any opt-in, and no email security records.
Launched on Product Hunt on June 24, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 2 weeks before launch. Our crawler found 13 technologies on this site, covering analytics, CDN, CSS frameworks, and developer tools. The stack includes Tailwind CSS, Ahrefs, and Cloudflare.
Notably, it's on one of the most common stacks we track, shared by 5,060 launches and more locked down than the typical Product Hunt launch.
