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

WebP Converter - instant, no uploads looks production-ready overall, with a thorough launch checklist, fast page loads, and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and no email security records.

Launched on Product Hunt on April 29, 2026. The site is hosted on Vercel, with a domain registered 2 weeks before launch. We've detected 11 technologies on this site, covering advertising, consent tooling, CSS frameworks, and DNS providers. The stack includes Google Funding Choices, Next.js, and React.

It's on one of the most common stacks we track, shared by 10,662 launches.
