Rtrvr
DeepSeek Flash flips the economics of browser-agent harnesses: cheap cached text, code generation, DOM-aware execution, and no screenshot tool loop renting a frontier model as the runtime.

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 26 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.
Rtrvr has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and incomplete email security.
Launched on Hacker News on June 25, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered in 2023. Our crawler found 22 technologies on this site, covering advertising, transactional email, security, and analytics. The stack includes Next.js, React, and Tailwind CSS.
It's also running the same core stack as 14,963 other launches.

Vibe Score Breakdown How?
| Signal | Points |
|---|---|
| AI CSS signals | +10 |
| 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.
