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

Synnoia ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. What needs work: incomplete email security.

Launched on PeerPush on July 18, 2026. The site is hosted on DigitalOcean App Platform and served through Cloudflare, with a domain registered 6 months before launch. The crawl picked up 17 technologies on this site, covering security, advertising, CDN, and CSS frameworks. The stack includes Tailwind CSS, Bluesky, and Cloudflare.

For context, it's one of 41 launches on this exact stack and tighter on security headers than most PeerPush launches.
