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

CtrlTool looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers and no email security records.

Launched on Hacker News on August 19, 2026. The site is served through Cloudflare, with a domain registered 2 days before launch. We've detected 10 technologies on this site, covering advertising, CDN, consent tooling, and CSS frameworks. The stack includes Google Funding Choices, Next.js, and React.

It's on one of the most common stacks we track, shared by 5,169 launches.
