CheckBy — Safety without constant tracking
This site was found by StackScope Discovery, our own
first-party launch detection. The tech stack below comes from that
discovery scan; the full analysis (screenshots, scores, page checks)
is added when the site is picked up by a launch platform.
CheckBy is a private safety check-in app that shares your plan and last known location only when a check-in fails.

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