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

Ajin covers some of the launch checklist, with clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and analytics without a consent banner.

Launched on Hacker News on June 7, 2026. The site is hosted on Fastly in the United States. Our crawler found 4 technologies on this site, covering analytics, CDN, business email, and hosting. The stack includes Fastly, Fastmail, and GitHub Pages.

Notably, it's running the same core stack as 942 other launches.
