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

JPG to PNG Converter looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers and incomplete email security.

Launched on Product Hunt on April 21, 2026. The site is served through Cloudflare, with a domain registered 12 weeks before launch. We've detected 7 technologies on this site, covering DNS providers, CDN, frameworks, and meta-frameworks. The stack includes Nuxt, Vue.js, and Cloudflare.

It's one of 89 launches on this exact stack.
