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

Tinkerandsee still has work before launch. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on August 24, 2026. The site is served through Cloudflare, with a domain registered 7 weeks before launch. The crawl picked up 2 technologies on this site, covering CDN and DNS providers. The stack includes Cloudflare and Cloudflare DNS.
