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.

tonvio scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing Permissions-Policy and Content-Security-Policy, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on July 19, 2026. The site is served through Cloudflare, with a domain registered 2 weeks before launch. The crawl picked up 15 technologies on this site, covering javascript library, seo, analytics, and CDN. The stack includes Next.js, React, and Tailwind CSS.

For context, it's on one of the most common stacks we track, shared by 3,923 launches and more locked down than the typical Product Hunt launch.
