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

Postpwn: Subscription Tracker covers some of the launch checklist, with complete legal pages and a thorough launch checklist. What needs work: missing several security headers, no robots.txt or sitemap, and no email security records.

Launched on Product Hunt on June 12, 2026. The site is hosted on Fastly in the United States, with a domain registered 4 months before launch. Our crawler found 5 technologies on this site, covering CDN, DNS providers, web fonts, and protocol. The stack includes Fastly, Google Fonts, and HSTS.
