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 11 June 2026; the live site may have changed since.

PostGrid still has work before launch. What needs work: missing several security headers, incomplete legal pages, and broken MTA-STS configuration.

Launched on Product Hunt on June 11, 2026. The site is hosted on Cloudflare in the United States, with a domain registered in 2014. The crawl picked up 18 technologies on this site, covering email marketing, transactional email, business email, and seo. The stack includes ActiveCampaign, Apple Business Connect, and Apple Domain Verification.

For context, it's on a stack we've seen on only 25 launches.
