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 25 August 2026; the live site may have changed since.

Live Caption Player still has work before launch. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on August 25, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 4 weeks before launch. The crawl picked up 10 technologies on this site, covering security, CDN, CSS frameworks, and developer tools. The stack includes Tailwind CSS, Cloudflare, and Cloudflare Bot Management.

For context, it's on one of the most common stacks we track, shared by 3,186 launches.
