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 30 April 2026; the live site may have changed since.
Larkin still has work before launch. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.
Launched on Hacker News on April 30, 2026. The site is hosted on Vercel. The crawl picked up 8 technologies on this site, covering CSS frameworks, DNS providers, email forwarding, and transactional email. The stack includes Next.js, React, and Tailwind CSS.
For context, it's running the same core stack as 10,671 other launches.
