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 16 June 2026; the live site may have changed since.
ThumbnailLab is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and no email security records.
Launched on Product Hunt on June 16, 2026. The site is hosted on Amazon.com in the United States. The crawl picked up 4 technologies on this site, covering web fonts, hosting, security, and seo. The stack includes Google Fonts, Google Search Console, and HSTS.
For context, it's running the same core stack as 1,382 other launches.
