Own this Launch?

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 1 July 2026; the live site may have changed since.

Fast share is early-stage. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on July 1, 2026. The site is served through Fastly. We've detected 7 technologies on this site, covering analytics, baas, CDN, and web fonts. The stack includes Fastly, Firebase, and Google Analytics.
