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 April 2026; the live site may have changed since.
F2File: Instant File Converter has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on April 27, 2026. The site is hosted on Vercel, with a domain registered 1 week before launch. Our crawler found 10 technologies on this site, covering analytics, CSS frameworks, DNS providers, and email forwarding. The stack includes Next.js, React, and Tailwind CSS.
It's also on one of the most common stacks we track, shared by 10,672 launches.
