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 August 2026; the live site may have changed since.
opini — Will your song reach the world? still has work before launch. Worth fixing first: missing several security headers, incomplete legal pages, and no sitemap.
Launched on Product Hunt on August 13, 2026. The site is served through Cloudflare, with a domain registered 6 weeks before launch. The crawl picked up 9 technologies on this site, covering analytics, CDN, DNS providers, and transactional email. The stack includes cdnjs, Chart.js, and Cloudflare.
