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

Instavites 2.0: The RSVP & Event Engine is largely in shape, with complete legal pages and clean crawl signals. Visible gaps: missing Permissions-Policy and Content-Security-Policy, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on April 20, 2026. The site is served through Cloudflare, with a domain registered in 2021. The crawl picked up 13 technologies on this site, covering analytics, CDN, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.

For context, it's on one of the most common stacks we track, shared by 3,880 launches and more locked down than the typical Product Hunt launch.
