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 21 May 2026; the live site may have changed since.

LevelMemo is early-stage. Visible gaps: missing several security headers, no robots.txt or sitemap, and incomplete email security.

Launched on Product Hunt on May 21, 2026. The site is hosted on SAKURA Internet Inc. in Japan. We've detected 3 technologies on this site, covering DNS providers, web fonts, and servers. The stack includes Google Fonts, IIJ DNS, and nginx.
