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 22 April 2026; the live site may have changed since.
Keepsule — Seal a Memory, Open It Later ships with the basics, with complete legal pages. Main gaps: missing several security headers, no robots.txt or sitemap, and incomplete email security.
Launched on Product Hunt on April 22, 2026. The site is served through Fastly. We've detected 5 technologies on this site, covering CDN, DNS providers, web fonts, and protocol. The stack includes Fastly, GoDaddy DNS, and Google Fonts.
