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

OJF - Online JSON Formatt ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: no X-Frame-Options and incomplete email security.

Launched on Product Hunt on August 3, 2026. The site is hosted on Firebase App Hosting. The crawl picked up 29 technologies on this site, covering advertising, hosting, analytics, and auth. The stack includes Google Funding Choices, Google Identity Platform, and Google Sign-In.

For context, it's running a stack combination we've seen on no other launch and tighter on security headers than most Product Hunt launches.
