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

Thread Context Cards — Context for Gmail ships with the basics. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt.

Launched on Product Hunt on June 24, 2026. The site is hosted on Fastly in the United States. We've detected 5 technologies on this site, covering CDN, hosting, protocol, and security. The stack includes Fastly, Firebase Hosting, and Google Search Console.

It's one of 79 launches on this exact stack.
