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

SprintCo scores highly overall, with complete legal pages and clean crawl signals. Visible gaps: missing Permissions-Policy and Content-Security-Policy and incomplete email security.

Launched on Product Hunt on April 28, 2026. The site is hosted on Heroku, with a domain registered 2 weeks before launch. The crawl picked up 8 technologies on this site, covering backend framework, CSS frameworks, developer tools, and DNS providers. The stack includes Tailwind CSS, Heroku, and HSTS.

For context, it's one of just 25 launches we've crawled on this exact stack and more locked down than the typical Product Hunt launch.
