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

opencanvas has the basics covered well, with complete legal pages, a thorough launch checklist, and fast page loads. What needs work: missing several security headers and incomplete email security.

Launched on Product Hunt on July 14, 2026. The site is hosted on Railway and served through Cloudflare, with a domain registered 5 days before launch. Our crawler found 7 technologies on this site, covering CDN, DNS providers, email forwarding, and web fonts. The stack includes Svelte, Cloudflare, and Cloudflare DNS.

It's also on a stack we've seen on only 6 launches.
