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

Victorpoughon still has work before launch. Main gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on April 18, 2026. The site is hosted on GitHub Pages and served through Fastly. The crawl picked up 3 technologies on this site, covering CDN, developer tools, and hosting. The stack includes Fastly, GitHub Pages, and Vite.

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