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 29 April 2026; the live site may have changed since.

Grimby — App Blocker ＆Focus covers some of the launch checklist, with complete legal pages. What needs work: missing several security headers, no robots.txt or sitemap, and no email security records.

Launched on Product Hunt on April 29, 2026. The site is hosted on Vercel. Our crawler found 4 technologies on this site, covering DNS providers, web fonts, hosting, and security. The stack includes Google Fonts, HSTS, and Vercel.

It's also running the same core stack as 2,955 other launches.
