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

impeccify.com ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and no email security records.

Launched on Product Hunt on April 2, 2026. The site is hosted on Vercel and served through Bunny CDN, with a domain registered 5 months before launch. The crawl picked up 17 technologies on this site, covering advertising, analytics, CDN, and security. The stack includes Clerk, Google Funding Choices, and Next.js.

For context, it's running the same core stack as 10,661 other launches.
