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

RoastLab is partway there, with a thorough launch checklist and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on July 17, 2026. The site is hosted on Vercel. The crawl picked up 6 technologies on this site, covering analytics, frameworks, hosting, and meta-frameworks. The stack includes Next.js, React, and HSTS.

For context, it's on one of the most common stacks we track, shared by 2,284 launches.
