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 21 July 2026; the live site may have changed since.

Deoit scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing Referrer-Policy and Permissions-Policy and no email security records.

Launched on Product Hunt on July 21, 2026. The site is hosted on Vercel. Our crawler found 10 technologies on this site, covering analytics, auth, baas, and web fonts. The stack includes Google Sign-In, Google Fonts, and Google Search Console.

It's also on one of the most common stacks we track, shared by 3,056 launches and more locked down than the typical Product Hunt launch.
