Screenshot of Sumday — the daily date equation

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

Sumday — the daily date equation is partway there, with a thorough launch checklist, well-configured email security, and fast page loads. Visible gaps: missing several security headers, incomplete legal pages, and no sitemap.

The site is served through Cloudflare, with a domain registered 2 weeks before launch. The crawl picked up 4 technologies on this site, covering CDN, DNS providers, business email, and frameworks. The stack includes Elm, Cloudflare, and Cloudflare DNS.

For context, it's one of only 2 launches we've crawled running Elm.
