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

Sidenote scores well across the board, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Main gaps: tracking cookies set before any opt-in and incomplete email security.

Launched on Product Hunt on June 24, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 7 weeks before launch. The crawl picked up 13 technologies on this site, covering business email, analytics, baas, and captcha. The stack includes Next.js, React, and Cloudflare Turnstile.

For context, it's on one of the most common stacks we track, shared by 1,725 launches and more locked down than the typical Product Hunt launch.
