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.
Hyday ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: no Content-Security-Policy and no email security records.
Launched on Product Hunt on August 26, 2026. The site is hosted on Google Cloud and served through Fastly. Our crawler found 8 technologies on this site, covering CDN, developer tools, DNS providers, and hosting. The stack includes Cloudflare DNS, Fastly, and Google Cloud.
It's also running the same core stack as 293 other launches and tighter on security headers than most Product Hunt launches.
