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

Sidebearing-trim still has work before launch. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on April 22, 2026. The site is hosted on GitHub Pages and served through Cloudflare. The crawl picked up 4 technologies on this site, covering CDN, developer tools, and hosting. The stack includes Cloudflare, Fastly, and GitHub Pages.

For context, it's on one of the most common stacks we track, shared by 1,758 launches.
