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.
Carry-On Size Widget ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing Permissions-Policy and Strict-Transport-Security and no email security records.
Launched on Product Hunt on April 21, 2026. The site is served through Cloudflare, with a domain registered 4 weeks before launch. We've detected 11 technologies on this site, covering advertising, analytics, CDN, and consent tooling. The stack includes Astro, Google Funding Choices, and Tailwind CSS.
It's running the same core stack as 467 other launches and tighter on security headers than most Product Hunt launches.
