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

En is partway there, with a thorough launch checklist. Main gaps: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Hacker News on August 12, 2026. The site is hosted on CLOUDI NEXTGEN SL in Spain, with a domain registered in 2019. The crawl picked up 9 technologies on this site, covering javascript library, advertising, analytics, and backend framework. The stack includes Stimulus, Carbon Ads, and GoatCounter.

For context, it's one of just 14 launches we've crawled on this exact stack.
