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

Arco is partway there, with complete legal pages, a thorough launch checklist, and fast page loads. Visible gaps: missing several security headers, no sitemap, and tracking cookies set before any opt-in.

Launched on Product Hunt on June 30, 2026. The site is hosted on Railway and served through Cloudflare, with a domain registered 1 week before launch. The crawl picked up 16 technologies on this site, covering analytics, ui library, CDN, and CSS frameworks. The stack includes Next.js, React, and Tailwind CSS.

For context, it's on one of the most common stacks we track, shared by 365 launches.
