Screenshot of PolyKeep - Keep All Your Languages Sharp

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 5 June 2026; the live site may have changed since.

PolyKeep - Keep All Your Languages Sharp looks production-ready overall, with complete legal pages, a thorough launch checklist, and fast page loads. Visible gaps: missing several security headers, analytics without a consent banner, and incomplete email security.

Launched on Product Hunt on June 5, 2026. The site is hosted on Cloudflare in the United States. We've detected 9 technologies on this site, covering analytics, build tooling, CDN, and DNS providers. The stack includes Vite, Cloudflare, and Cloudflare DNS.

It's on one of the most common stacks we track, shared by 540 launches.
