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

Harmber has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers and no email security records.

Launched on Product Hunt on August 10, 2026. The site is hosted on Vercel. Our crawler found 8 technologies on this site, covering advertising, consent tooling, DNS providers, and business email. The stack includes Google Funding Choices, Google Ads, and Google AdSense.

It's also on one of the most common stacks we track, shared by 3,571 launches.
