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 1 July 2026; the live site may have changed since.

Sidedoor looks production-ready overall, with a complete set of security headers, a thorough launch checklist, and clean crawl signals. Worth fixing first: incomplete legal pages, tracking cookies set before any opt-in, and incomplete email security.

Launched on Hacker News on July 1, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered in 2022. We've detected 31 technologies on this site, covering analytics, auth, social embeds, and business email. The stack includes Clerk, Google OAuth, and Google Sign-In.

It's running the same core stack as 9,067 other launches and tighter on security headers than most Hacker News launches.
