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 22 June 2026; the live site may have changed since.

Dayoff scores well across the board, with complete legal pages, fast page loads, and clean crawl signals. Main gaps: no Permissions-Policy, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on June 22, 2026. The site is hosted on Fly.io in the United States. The crawl picked up 8 technologies on this site, covering transactional email, analytics, CSS frameworks, and DNS providers. The stack includes Tailwind CSS, Amazon SES, and Fly.io.

For context, it's one of 40 launches on this exact stack and more locked down than the typical Product Hunt launch.
