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 8 May 2026; the live site may have changed since.
WillItInbox looks production-ready overall, with complete legal pages, a thorough launch checklist, and well-configured email security. Visible gaps: missing several security headers.
Launched on Product Hunt on May 8, 2026. The site is served through Cloudflare, with a domain registered 5 days before launch. We've detected 10 technologies on this site, covering CDN, CSS frameworks, developer tools, and DNS providers. The stack includes Tailwind CSS, Caddy, and Cloudflare.
It's one of only 40 launches we've crawled running SMTP2GO.
