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

aipen.ink is largely in shape, with a thorough launch checklist and clean crawl signals. Visible gaps: missing several security headers, placeholder text in the legal pages, and incomplete email security.

Launched on Product Hunt on June 17, 2026. The site is hosted on Google LLC in the United States, with a domain registered 12 weeks before launch. The crawl picked up 12 technologies on this site, covering frameworks, baas, CDN, and directory. The stack includes Express, React, and Cloudflare.

For context, it's one of just 2 launches we've crawled on this exact stack.
