Kencode

I've hit the same "pack state into a tiny string" problem four times now. Here's the library that came out of it, and a detour on why kotlinx.serialization is so cool to build on.

StackScope records what new websites are built with, the week they launch. Most we find ourselves, by watching public internet infrastructure for brand-new sites; the rest come from Product Hunt, Hacker News and PeerPush. We crawled this one for its tech stack and scored it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 1 May 2026; the live site may have changed since.

Every technology below links to its own page: which other new sites launched with it. Vendors and agencies watch those pages with Stackdar and hear about new adopters the week they ship, from £15 a month.

Kencode covers some of the launch checklist, with a thorough launch checklist, well-configured email security, and fast page loads. Visible gaps: missing several security headers and incomplete legal pages.

Launched on Hacker News on May 1, 2026. The site is hosted on DigitalOcean App Platform and served through Cloudflare, with a domain registered 5 months before launch. Our crawler found 10 technologies on this site, covering analytics, CDN, cloud, and DNS providers. The stack includes Amazon Web Services, Ceph, and Cloudflare.

It's also one of 70 launches on this exact stack.
