Own this Launch?

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

DisplayTools is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers and no email security records.

Launched on Product Hunt on June 5, 2026. The site is hosted on Amazon.com in the United States. The crawl picked up 9 technologies on this site, covering advertising, analytics, build tooling, and consent tooling. The stack includes Google Funding Choices, Tailwind CSS, and Vite.

For context, it's on one of the most common stacks we track, shared by 312 launches.
