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 11 August 2026; the live site may have changed since.

NijiSwipe is largely in shape, with complete legal pages, a thorough launch checklist, and well-configured email security. Visible gaps: missing several security headers and tracking cookies set before any opt-in.

Launched on Product Hunt on August 11, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 3 days before launch. The crawl picked up 12 technologies on this site, covering analytics, CDN, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.

For context, it's on one of the most common stacks we track, shared by 12,865 launches.
