Own this Launch?

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

Synco ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: tracking cookies set before any opt-in and no email security records.

Launched on Product Hunt on August 26, 2026. The site is hosted on Vercel. The crawl picked up 11 technologies on this site, covering analytics, CSS frameworks, web fonts, and frameworks. The stack includes Next.js, React, and Tailwind CSS.

For context, it's running the same core stack as 14,158 other launches and tighter on security headers than most Product Hunt launches.
