Supso
A memory-safe, fast, spec-compliant XML library for Rust, with drop-in replacement for libxml2.
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 5 June 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.
Supso ships with the basics, with a thorough launch checklist. Main gaps: missing several security headers, incomplete legal pages, and no sitemap.
Launched on Hacker News on June 5, 2026. The site is hosted on Render and served through Cloudflare. We've detected 10 technologies on this site, covering transactional email, CDN, DNS providers, and documentation. The stack includes Astro, Cloudflare, and DNSimple.

Vibe Score Breakdown How?
| Signal | Points |
|---|---|
| AI copy signals | +5 |
| AI palette signals | +5 |
This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
