Synchrium

A synchronized timer that runs across peers. Silent focus until the count reaches zero — then mics and/or cameras can come up, together.

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

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

Launched on Hacker News on August 10, 2026. The site is served through Cloudflare, with a domain registered 3 months before launch. Our crawler found 8 technologies on this site, covering analytics, CDN, developer tools, and DNS providers. The stack includes Cloudflare, Cloudflare DNS, and Google Fonts.

It's also more locked down than the typical Hacker News launch.
