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

Email Jachai scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Visible gaps: incomplete email security.

Launched on Product Hunt on August 9, 2026. The site is served through Cloudflare, with a domain registered 1 week before launch. The crawl picked up 20 technologies on this site, covering advertising, analytics, social embeds, and captcha. The stack includes Next.js, React, and Tailwind CSS.

For context, it's on one of the most common stacks we track, shared by 4,773 launches and more locked down than the typical Product Hunt launch.
