This Week in Obsidian

Welcome back to another Tuesday edition of This Week in Obsidian.

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

This Week in Obsidian is largely in shape, with complete legal pages, a thorough launch checklist, and well-configured email security. Main gaps: missing several security headers, no sitemap, and analytics without a consent banner.

Launched on Hacker News on June 10, 2026. The site is hosted on Cloudflare in the United States, with a domain registered in 2010. The crawl picked up 13 technologies on this site, covering security, analytics, CDN, and cloud. The stack includes Express, Amazon Web Services, and Cloudflare.

For context, it's on one of the most common stacks we track, shared by 130 launches.
