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

Custom Letterhead looks production-ready overall, with complete legal pages and a thorough launch checklist. Visible gaps: no Permissions-Policy, no robots.txt or sitemap, and tracking cookies set before any opt-in.

Launched on Product Hunt on August 23, 2026. The site is hosted on Amazon.com in the United States, with a domain registered in 2012. We've detected 16 technologies on this site, covering analytics, chat widgets, email marketing, and advertising. The stack includes Tailwind CSS, Apache, and Brevo.

It's on one of the most common stacks we track, shared by 7,271 launches and more locked down than the typical Product Hunt launch.
