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 13 April 2026; the live site may have changed since.

OKBrain Harness is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers and incomplete email security.

Launched on Product Hunt on April 2, 2026. The site is hosted on Amazon.com in the United States. The crawl picked up 8 technologies on this site, covering DNS providers, business email, email marketing, and web fonts. The stack includes Next.js, React, and DNSimple.

For context, it's on one of the most common stacks we track, shared by 1,289 launches.
