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

Cleanmails is partway there, with fast page loads and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and no email security records.

Launched on Product Hunt on August 23, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 3 weeks before launch. The crawl picked up 17 technologies on this site, covering security, ui library, analytics, and CDN. The stack includes Google, Next.js, and React.

For context, it's on one of the most common stacks we track, shared by 13,820 launches.
