Own this Launch?

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 25 April 2026; the live site may have changed since.

Sun is missing several launch fundamentals. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on April 25, 2026. The site is hosted on GitHub Pages and served through Fastly, with a domain registered 2 weeks before launch. Our crawler found 5 technologies on this site, covering CDN, CSS frameworks, developer tools, and web fonts. The stack includes Tailwind CSS, Fastly, and GitHub Pages.

It's also on one of the most common stacks we track, shared by 208 launches.
