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

Tip Calculator is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and no email security records.

Launched on Product Hunt on April 30, 2026. The site is hosted on Hostinger. The crawl picked up 6 technologies on this site, covering DNS providers, web fonts, hosting, and protocol. The stack includes Google Fonts, Google Search Console, and Hostinger.

For context, it's running the same core stack as 888 other launches.
