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

SagerBuddy ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: no Permissions-Policy, analytics without a consent banner, and no email security records.

Launched on Product Hunt on June 13, 2026. The site is hosted on Hangzhou Alibaba Advertising Co. in China, with a domain registered 9 weeks before launch. The crawl picked up 13 technologies on this site, covering social embeds, ai api, analytics, and CSS frameworks. The stack includes Next.js, React, and Tailwind CSS.

For context, it's one of 75 launches on this exact stack and tighter on security headers than most Product Hunt launches.
