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

Sleeve | Research Investment Managers has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers and no email security records.

Launched on Product Hunt on July 6, 2026. The site is hosted on Vercel and served through Cloudflare. Our crawler found 16 technologies on this site, covering analytics, javascript library, security, and advertising. The stack includes Clerk, Next.js, and React.

It's also on one of the most common stacks we track, shared by 1,998 launches.
