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 10 April 2026; the live site may have changed since.

Pronvo ships with the basics, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on April 7, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 1 week before launch. We've detected 9 technologies on this site, covering CDN, CSS frameworks, DNS providers, and email forwarding. The stack includes Next.js, React, and Tailwind CSS.

It's on one of the most common stacks we track, shared by 10,672 launches.
