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

Api Key Chain ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: no Permissions-Policy and no email security records.

Launched on Product Hunt on July 16, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 1 week before launch. Our crawler found 35 technologies on this site, covering ai api, analytics, transactional email, and security. The stack includes Next.js, React, and Tailwind CSS.

It's also a rare EmailJS sighting, just 28 in our data and tighter on security headers than most Product Hunt launches.
