Screenshot of ScreenCaption

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

ScreenCaption is early-stage. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on June 26, 2026. The site is hosted on Fastly in the United States. We've detected 6 technologies on this site, covering analytics, CDN, CSS frameworks, and developer tools. The stack includes Tailwind CSS, Fastly, and HSTS.

It's running the same core stack as 5,131 other launches.
