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 28 June 2026; the live site may have changed since.

Stemm covers some of the launch checklist, with a thorough launch checklist. Visible gaps: missing several security headers, incomplete legal pages, and no sitemap.

Launched on PeerPush on June 28, 2026. The site is hosted on Cloudflare in the United States. Our crawler found 11 technologies on this site, covering analytics, transactional email, CDN, and DNS providers. The stack includes Next.js, React, and Amazon SES.

Notably, it's on one of the most common stacks we track, shared by 1,815 launches.
