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 21 April 2026; the live site may have changed since.

SaveSync scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Main gaps: incomplete email security.

Launched on Product Hunt on April 21, 2026. The site is hosted on Render and served through Cloudflare. The crawl picked up 22 technologies on this site, covering ai api, hosting, analytics, and baas. The stack includes Next.js, React, and Tailwind CSS.

For context, it's the only launch we've crawled on this exact stack and more locked down than the typical Product Hunt launch.
